Client

class Lambda.Client

A low-level client representing AWS Lambda

Overview

Lambda is a compute service that lets you run code without provisioning or managing servers. Lambda runs your code on a high-availability compute infrastructure and performs all of the administration of the compute resources, including server and operating system maintenance, capacity provisioning and automatic scaling, code monitoring and logging. With Lambda, you can run code for virtually any type of application or backend service. For more information about the Lambda service, see What is Lambda in the Lambda Developer Guide .

The Lambda API Reference provides information about each of the API methods, including details about the parameters in each API request and response.

You can use Software Development Kits (SDKs), Integrated Development Environment (IDE) Toolkits, and command line tools to access the API. For installation instructions, see Tools for Amazon Web Services.

For a list of Region-specific endpoints that Lambda supports, see Lambda endpoints and quotas in the Amazon Web Services General Reference. .

When making the API calls, you will need to authenticate your request by providing a signature. Lambda supports signature version 4. For more information, see Signature Version 4 signing process in the Amazon Web Services General Reference. .

CA certificates

Because Amazon Web Services SDKs use the CA certificates from your computer, changes to the certificates on the Amazon Web Services servers can cause connection failures when you attempt to use an SDK. You can prevent these failures by keeping your computer's CA certificates and operating system up-to-date. If you encounter this issue in a corporate environment and do not manage your own computer, you might need to ask an administrator to assist with the update process. The following list shows minimum operating system and Java versions:

  • Microsoft Windows versions that have updates from January 2005 or later installed contain at least one of the required CAs in their trust list.
  • Mac OS X 10.4 with Java for Mac OS X 10.4 Release 5 (February 2007), Mac OS X 10.5 (October 2007), and later versions contain at least one of the required CAs in their trust list.
  • Red Hat Enterprise Linux 5 (March 2007), 6, and 7 and CentOS 5, 6, and 7 all contain at least one of the required CAs in their default trusted CA list.
  • Java 1.4.2_12 (May 2006), 5 Update 2 (March 2005), and all later versions, including Java 6 (December 2006), 7, and 8, contain at least one of the required CAs in their default trusted CA list.

When accessing the Lambda management console or Lambda API endpoints, whether through browsers or programmatically, you will need to ensure your client machines support any of the following CAs:

  • Amazon Root CA 1
  • Starfield Services Root Certificate Authority - G2
  • Starfield Class 2 Certification Authority

Root certificates from the first two authorities are available from Amazon trust services, but keeping your computer up-to-date is the more straightforward solution. To learn more about ACM-provided certificates, see Amazon Web Services Certificate Manager FAQs.

These are the available methods:

add_layer_version_permission(**kwargs)

Adds permissions to the resource-based policy of a version of an Lambda layer. Use this action to grant layer usage permission to other accounts. You can grant permission to a single account, all accounts in an organization, or all Amazon Web Services accounts.

To revoke permission, call RemoveLayerVersionPermission with the statement ID that you specified when you added it.

response = client.add_layer_version_permission(
    Action='lambda:GetLayerVersion',
    LayerName='my-layer',
    Principal='223456789012',
    StatementId='xaccount',
    VersionNumber=1,
)

print(response)

Expected Output:

{
    'RevisionId': '35d87451-f796-4a3f-a618-95a3671b0a0c',
    'Statement': '{"Sid":"xaccount","Effect":"Allow","Principal":{"AWS":"arn:aws:iam::223456789012:root"},"Action":"lambda:GetLayerVersion","Resource":"arn:aws:lambda:us-east-2:123456789012:layer:my-layer:1"}',
    'ResponseMetadata': {
        '...': '...',
    },
}
add_permission(**kwargs)

Grants an Amazon Web Services service, account, or organization permission to use a function. You can apply the policy at the function level, or specify a qualifier to restrict access to a single version or alias. If you use a qualifier, the invoker must use the full Amazon Resource Name (ARN) of that version or alias to invoke the function. Note: Lambda does not support adding policies to version $LATEST.

To grant permission to another account, specify the account ID as the Principal . To grant permission to an organization defined in Organizations, specify the organization ID as the PrincipalOrgID . For Amazon Web Services services, the principal is a domain-style identifier defined by the service, like s3.amazonaws.com or sns.amazonaws.com . For Amazon Web Services services, you can also specify the ARN of the associated resource as the SourceArn . If you grant permission to a service principal without specifying the source, other accounts could potentially configure resources in their account to invoke your Lambda function.

This action adds a statement to a resource-based permissions policy for the function. For more information about function policies, see Lambda Function Policies.

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
close()

Closes underlying endpoint connections.

create_alias(**kwargs)

Creates an alias for a Lambda function version. Use aliases to provide clients with a function identifier that you can update to invoke a different version.

You can also map an alias to split invocation requests between two versions. Use the RoutingConfig parameter to specify a second version and the percentage of invocation requests that it receives.

create_event_source_mapping(**kwargs)

Creates a mapping between an event source and an Lambda function. Lambda reads items from the event source and invokes the function.

For details about how to configure different event sources, see the following topics.

The following error handling options are available only for stream sources (DynamoDB and Kinesis):

  • BisectBatchOnFunctionError - If the function returns an error, split the batch in two and retry.
  • DestinationConfig - Send discarded records to an Amazon SQS queue or Amazon SNS topic.
  • MaximumRecordAgeInSeconds - Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires
  • MaximumRetryAttempts - Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.
  • ParallelizationFactor - Process multiple batches from each shard concurrently.

For information about which configuration parameters apply to each event source, see the following topics.

Parameters
  • EventSourceArn (string) --

    The Amazon Resource Name (ARN) of the event source.

    • Amazon Kinesis - The ARN of the data stream or a stream consumer.
    • Amazon DynamoDB Streams - The ARN of the stream.
    • Amazon Simple Queue Service - The ARN of the queue.
    • Amazon Managed Streaming for Apache Kafka - The ARN of the cluster.
  • FunctionName (string) --

    [REQUIRED]

    The name of the Lambda function.

    Name formats
    • Function name - MyFunction .
    • Function ARN - arn:aws:lambda:us-west-2:123456789012:function:MyFunction .
    • Version or Alias ARN - arn:aws:lambda:us-west-2:123456789012:function:MyFunction:PROD .
    • Partial ARN - 123456789012:function:MyFunction .

    The length constraint applies only to the full ARN. If you specify only the function name, it's limited to 64 characters in length.

  • Enabled (boolean) --

    When true, the event source mapping is active. When false, Lambda pauses polling and invocation.

    Default: True

  • BatchSize (integer) --

    The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

    • Amazon Kinesis - Default 100. Max 10,000.
    • Amazon DynamoDB Streams - Default 100. Max 10,000.
    • Amazon Simple Queue Service - Default 10. For standard queues the max is 10,000. For FIFO queues the max is 10.
    • Amazon Managed Streaming for Apache Kafka - Default 100. Max 10,000.
    • Self-managed Apache Kafka - Default 100. Max 10,000.
    • Amazon MQ (ActiveMQ and RabbitMQ) - Default 100. Max 10,000.
  • FilterCriteria (dict) --

    (Streams and Amazon SQS) An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering.

    • Filters (list) --

      A list of filters.

      • (dict) --

        A structure within a FilterCriteria object that defines an event filtering pattern.

        • Pattern (string) --

          A filter pattern. For more information on the syntax of a filter pattern, see Filter rule syntax.

  • MaximumBatchingWindowInSeconds (integer) --

    The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

    For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, and Amazon MQ event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

    Related setting: For streams and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

  • ParallelizationFactor (integer) -- (Streams only) The number of batches to process from each shard concurrently.
  • StartingPosition (string) -- The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK Streams sources. AT_TIMESTAMP is supported only for Amazon Kinesis streams.

Response Structure

  • (dict) --

    A mapping between an Amazon Web Services resource and a Lambda function. For details, see CreateEventSourceMapping.

    • UUID (string) --

      The identifier of the event source mapping.

    • StartingPosition (string) --

      The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK stream sources. AT_TIMESTAMP is supported only for Amazon Kinesis streams.

    • StartingPositionTimestamp (datetime) --

      With StartingPosition set to AT_TIMESTAMP , the time from which to start reading.

    • BatchSize (integer) --

      The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

      Default value: Varies by service. For Amazon SQS, the default is 10. For all other services, the default is 100.

      Related setting: When you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

    • MaximumBatchingWindowInSeconds (integer) --

      The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

      For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, and Amazon MQ event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

      Related setting: For streams and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

    },
}
create_function(**kwargs)

Creates a Lambda function. To create a function, you need a deployment package and an execution role. The deployment package is a .zip file archive or container image that contains your function code. The execution role grants the function permission to use Amazon Web Services services, such as Amazon CloudWatch Logs for log streaming and X-Ray for request tracing.

You set the package type to Image if the deployment package is a container image. For a container image, the code property must include the URI of a container image in the Amazon ECR registry. You do not need to specify the handler and runtime properties.

You set the package type to Zip if the deployment package is a .zip file archive. For a .zip file archive, the code property specifies the location of the .zip file. You must also specify the handler and runtime properties. The code in the deployment package must be compatible with the target instruction set architecture of the function (x86-64 or arm64 ). If you do not specify the architecture, the default value is x86-64 .

When you create a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute or so. During this time, you can't invoke or modify the function. The State , StateReason , and StateReasonCode fields in the response from GetFunctionConfiguration indicate when the function is ready to invoke. For more information, see Function States.

A function has an unpublished version, and can have published versions and aliases. The unpublished version changes when you update your function's code and configuration. A published version is a snapshot of your function code and configuration that can't be changed. An alias is a named resource that maps to a version, and can be changed to map to a different version. Use the Publish parameter to create version 1 of your function from its initial configuration.

The other parameters let you configure version-specific and function-level settings. You can modify version-specific settings later with UpdateFunctionConfiguration. Function-level settings apply to both the unpublished and published versions of the function, and include tags ( TagResource ) and per-function concurrency limits ( PutFunctionConcurrency ).

You can use code signing if your deployment package is a .zip file archive. To enable code signing for this function, specify the ARN of a code-signing configuration. When a user attempts to deploy a code package with UpdateFunctionCode, Lambda checks that the code package has a valid signature from a trusted publisher. The code-signing configuration includes set set of signing profiles, which define the trusted publishers for this function.

If another account or an Amazon Web Services service invokes your function, use AddPermission to grant permission by creating a resource-based IAM policy. You can grant permissions at the function level, on a version, or on an alias.

To invoke your function directly, use Invoke. To invoke your function in response to events in other Amazon Web Services services, create an event source mapping ( CreateEventSourceMapping ), or configure a function trigger in the other service. For more information, see Invoking Functions.

Response Structure

  • (dict) --

    A mapping between an Amazon Web Services resource and a Lambda function. For details, see CreateEventSourceMapping.

    • UUID (string) --

      The identifier of the event source mapping.

    • StartingPosition (string) --

      The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK stream sources. AT_TIMESTAMP is supported only for Amazon Kinesis streams.

    • StartingPositionTimestamp (datetime) --

      With StartingPosition set to AT_TIMESTAMP , the time from which to start reading.

    • BatchSize (integer) --

      The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

      Default value: Varies by service. For Amazon SQS, the default is 10. For all other services, the default is 100.

      Related setting: When you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

    • MaximumBatchingWindowInSeconds (integer) --

      The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

      For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, and Amazon MQ event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

      Related setting: For streams and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

Response Structure

  • (dict) --

    A mapping between an Amazon Web Services resource and a Lambda function. For details, see CreateEventSourceMapping.

    • UUID (string) --

      The identifier of the event source mapping.

    • StartingPosition (string) --

      The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK stream sources. AT_TIMESTAMP is supported only for Amazon Kinesis streams.

    • StartingPositionTimestamp (datetime) --

      With StartingPosition set to AT_TIMESTAMP , the time from which to start reading.

    • BatchSize (integer) --

      The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

      Default value: Varies by service. For Amazon SQS, the default is 10. For all other services, the default is 100.

      Related setting: When you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

    • MaximumBatchingWindowInSeconds (integer) --

      The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

      For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, and Amazon MQ event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

      Related setting: For streams and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

    • ParallelizationFactor (integer) --

get_waiter(waiter_name)

Returns an object that can wait for some condition.

Return type
botocore.waiter.Waiter
invoke(**kwargs)

Invokes a Lambda function. You can invoke a function synchronously (and wait for the response), or asynchronously. To invoke a function asynchronously, set InvocationType to Event .

For synchronous invocation, details about the function response, including errors, are included in the response body and headers. For either invocation type, you can find more information in the execution log and trace.

When an error occurs, your function may be invoked multiple times. Retry behavior varies by error type, client, event source, and invocation type. For example, if you invoke a function asynchronously and it returns an error, Lambda executes the function up to two more times. For more information, see Retry Behavior.

For asynchronous invocation, Lambda adds events to a queue before sending them to your function. If your function does not have enough capacity to keep up with the queue, events may be lost. Occasionally, your function may receive the same event multiple times, even if no error occurs. To retain events that were not processed, configure your function with a dead-letter queue.

The status code in the API response doesn't reflect function errors. Error codes are reserved for errors that prevent your function from executing, such as permissions errors, limit errors, or issues with your function's code and configuration. For example, Lambda returns TooManyRequestsException if executing the function would cause you to exceed a concurrency limit at either the account level (ConcurrentInvocationLimitExceeded ) or function level (ReservedFunctionConcurrentInvocationLimitExceeded ).

For functions with a long timeout, your client might be disconnected during synchronous invocation while it waits for a response. Configure your HTTP client, SDK, firewall, proxy, or operating system to allow for long connections with timeout or keep-alive settings.

This operation requires permission for the lambda:InvokeFunction action. For details on how to set up permissions for cross-account invocations, see Granting function access to other accounts.

    Payload=b'bytes'|file,
    Qualifier='string'
)
Parameters
  • FunctionName (string) --

    [REQUIRED]

    The name of the Lambda function, version, or alias.

    Name formats
    • Function name - my-function (name-only), my-function:v1 (with alias).

  • InvocationType (string) --

    Choose from the following options.

    • RequestResponse (default) - Invoke the function synchronously. Keep the connection open until the function returns a response or times out. The API response includes the function response and additional data.
    • Event - Invoke the function asynchronously. Send events that fail multiple times to the function's dead-letter queue (if it's configured). The API response only includes a status code.
    • DryRun - Validate parameter values and verify that the user or role has permission to invoke the function.
  • LogType (string) -- Set to Tail to include the execution log in the response. Applies to synchronously invoked functions only.
  • ClientContext (string) -- Up to 3583 bytes of base64-encoded data about the invoking client to pass to the function in the context object.
  • Payload (bytes or seekable file-like object) --

    The JSON that you want to provide to your Lambda function as input.

    You can enter the JSON directly. For example, --payload '{ "key": "value" }' . You can also specify a file path. For example, --payload file://payload.json .

  • Qualifier (string) -- Specify a version or alias to invoke a published version of the function.

Response Structure

  • (dict) --

    • NextMarker (string) --

      A pagination token that's returned when the response doesn't contain all event source mappings.

    • EventSourceMappings (list) --

      A list of event source mappings.

      • (dict) --

        A mapping between an Amazon Web Services resource and a Lambda function. For details, see CreateEventSourceMapping.

        • UUID (string) --

          The identifier of the event source mapping.

        • StartingPosition (string) --

          The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK stream sources. AT_TIMESTAMP is supported only for Amazon Kinesis streams.

        • StartingPositionTimestamp (datetime) --

          With StartingPosition set to AT_TIMESTAMP , the time from which to start reading.

        • BatchSize (integer) --

          The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

          Default value: Varies by service. For Amazon SQS, the default is 10. For all other services, the default is 100.

          Related setting: When you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

        • MaximumBatchingWindowInSeconds (integer) --

          The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

          For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, and Amazon MQ event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

          Related setting: For streams and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

        • ParallelizationFactor (integer) --

          (Streams only) The number of batches to process concurrently from each shard. The default value is 1.

publish_version(**kwargs)

Creates a version from the current code and configuration of a function. Use versions to create a snapshot of your function code and configuration that doesn't change.

Lambda doesn't publish a version if the function's configuration and code haven't changed since the last version. Use UpdateFunctionCode or UpdateFunctionConfiguration to update the function before publishing a version.

Clients can invoke versions directly or with an alias. To create an alias, use CreateAlias.

put_function_concurrency(**kwargs)

Sets the maximum number of simultaneous executions for a function, and reserves capacity for that concurrency level.

Concurrency settings apply to the function as a whole, including all published versions and the unpublished version. Reserving concurrency both ensures that your function has capacity to process the specified number of events simultaneously, and prevents it from scaling beyond that level. Use GetFunction to see the current setting for a function.

Use GetAccountSettings to see your Regional concurrency limit. You can reserve concurrency for as many functions as you like, as long as you leave at least 100 simultaneous executions unreserved for functions that aren't configured with a per-function limit. For more information, see Managing Concurrency.

)
Parameters
  • FunctionName (string) --

    [REQUIRED]

    The name of the Lambda function.

    Name formats
    • Function name - my-function .
    • Function ARN - arn:aws:lambda:us-west-2:123456789012:function:my-function .
    • Partial ARN - 123456789012:function:my-function .

    The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • ReservedConcurrentExecutions (integer) --

    [REQUIRED]

    The number of simultaneous executions to reserve for the function.

Return type

dict

Returns

Response Syntax

{
    'ReservedConcurrentExecutions': 123
}

Response Structure

  • (dict) --

    • ReservedConcurrentExecutions (integer) --

      The number of concurrent executions that are reserved for this function. For more information, see Managing Concurrency.

Exceptions

  • Lambda.Client.exceptions.ServiceException
  • Lambda.Client.exceptions.InvalidParameterValueException
  • Lambda.Client.exceptions.ResourceNotFoundException
  • Lambda.Client.exceptions.TooManyRequestsException
  • Lambda.Client.exceptions.ResourceConflictException

Examples

The following example configures 100 reserved concurrent executions for the my-function function.

response = client.put_function_concurrency(
    FunctionName='my-function',
    ReservedConcurrentExecutions=100,
)

print(response)

    'ResponseMetadata': {
        '...': '...',
    },
}
put_function_event_invoke_config(**kwargs)

Configures options for asynchronous invocation on a function, version, or alias. If a configuration already exists for a function, version, or alias, this operation overwrites it. If you exclude any settings, they are removed. To set one option without affecting existing settings for other options, use UpdateFunctionEventInvokeConfig.

By default, Lambda retries an asynchronous invocation twice if the function returns an error. It retains events in a queue for up to six hours. When an event fails all processing attempts or stays in the asynchronous invocation queue for too long, Lambda discards it. To retain discarded events, configure a dead-letter queue with UpdateFunctionConfiguration.

To send an invocation record to a queue, topic, function, or event bus, specify a destination. You can configure separate destinations for successful invocations (on-success) and events that fail all processing attempts (on-failure). You can configure destinations in addition to or instead of a dead-letter queue.

Parameters
  • UUID (string) --

    [REQUIRED]

    The identifier of the event source mapping.

  • FunctionName (string) --

    The name of the Lambda function.

    Name formats
    • Function name - MyFunction .
    • Function ARN - arn:aws:lambda:us-west-2:123456789012:function:MyFunction .
    • Version or Alias ARN - arn:aws:lambda:us-west-2:123456789012:function:MyFunction:PROD .
    • Partial ARN - 123456789012:function:MyFunction .

    The length constraint applies only to the full ARN. If you specify only the function name, it's limited to 64 characters in length.

  • Enabled (boolean) --

    When true, the event source mapping is active. When false, Lambda pauses polling and invocation.

    Default: True

  • BatchSize (integer) --

    The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

    • Amazon Kinesis - Default 100. Max 10,000.
    • Amazon DynamoDB Streams - Default 100. Max 10,000.
    • Amazon Simple Queue Service - Default 10. For standard queues the max is 10,000. For FIFO queues the max is 10.
    • Amazon Managed Streaming for Apache Kafka - Default 100. Max 10,000.
    • Self-managed Apache Kafka - Default 100. Max 10,000.
    • Amazon MQ (ActiveMQ and RabbitMQ) - Default 100. Max 10,000.
  • FilterCriteria (dict) --

    (Streams and Amazon SQS) An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering.

    • Filters (list) --

  • MaximumBatchingWindowInSeconds (integer) --

    The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

    For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, and Amazon MQ event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

    Related setting: For streams and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

update_function_code(**kwargs)

Updates a Lambda function's code. If code signing is enabled for the function, the code package must be signed by a trusted publisher. For more information, see Configuring code signing.

If the function's package type is Image , you must specify the code package in ImageUri as the URI of a container image in the Amazon ECR registry.

If the function's package type is Zip , you must specify the deployment package as a .zip file archive. Enter the Amazon S3 bucket and key of the code .zip file location. You can also provide the function code inline using the ZipFile field.

The code in the deployment package must be compatible with the target instruction set architecture of the function (x86-64 or arm64 ).

The function's code is locked when you publish a version. You can't modify the code of a published version, only the unpublished version.

Note

For a function defined as a container image, Lambda resolves the image tag to an image digest. In Amazon ECR, if you update the image tag to a new image, Lambda does not automatically update the function.

  • S3ObjectVersion (string) -- For versioned objects, the version of the deployment package object to use.
  • ImageUri (string) -- URI of a container image in the Amazon ECR registry. Do not use for a function defined with a .zip file archive.
  • Publish (boolean) -- Set to true to publish a new version of the function after updating the code. This has the same effect as calling PublishVersion separately.
  • DryRun (boolean) -- Set to true to validate the request parameters and access permissions without modifying the function code.
  • RevisionId (string) -- Only update the function if the revision ID matches the ID that's specified. Use this option to avoid modifying a function that has changed since you last read it.
  • Architectures (list) --

update_function_configuration(**kwargs)

Modify the version-specific settings of a Lambda function.

When you update a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute. During this time, you can't modify the function, but you can still invoke it. The LastUpdateStatus , LastUpdateStatusReason , and LastUpdateStatusReasonCode fields in the response from GetFunctionConfiguration indicate when the update is complete and the function is processing events with the new configuration. For more information, see Function States.

These settings can vary between versions of a function and are locked when you publish a version. You can't modify the configuration of a published version, only the unpublished version.

To configure function concurrency, use PutFunctionConcurrency. To grant invoke permissions to an account or Amazon Web Services service, use AddPermission.

    • EventSourceMappings (list) --

      A list of event source mappings.

      • (dict) --

        A mapping between an Amazon Web Services resource and a Lambda function. For details, see CreateEventSourceMapping.

        • UUID (string) --

          The identifier of the event source mapping.

        • StartingPosition (string) --

          The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK stream sources. AT_TIMESTAMP is supported only for Amazon Kinesis streams.

        • StartingPositionTimestamp (datetime) --

          With StartingPosition set to AT_TIMESTAMP , the time from which to start reading.

        • BatchSize (integer) --

          The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

          Default value: Varies by service. For Amazon SQS, the default is 10. For all other services, the default is 100.

          Related setting: When you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

        • MaximumBatchingWindowInSeconds (integer) --

          The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

          For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, and Amazon MQ event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

          Related setting: For streams and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

        • ParallelizationFactor (integer) --
