Request Syntax

response = client.put_provisioned_concurrency_config(
    FunctionName='string',
    Qualifier='string',
    ProvisionedConcurrentExecutions=123
)

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.

• Qualifier (string) --

  [REQUIRED]

  The version number or alias name.

• ProvisionedConcurrentExecutions (integer) --

  [REQUIRED]

  The amount of provisioned concurrency to allocate for the version or alias.

Return type

dict

Response Syntax

{
    'RequestedProvisionedConcurrentExecutions': 123,
    'AvailableProvisionedConcurrentExecutions': 123,
    'AllocatedProvisionedConcurrentExecutions': 123,
    'Status': 'IN_PROGRESS'|'READY'|'FAILED',
    'StatusReason': 'string',

}

Response Structure

• (dict) --

  • RequestedProvisionedConcurrentExecutions (integer) --

    The amount of provisioned concurrency requested.

  • AvailableProvisionedConcurrentExecutions (integer) --

    The amount of provisioned concurrency available.

  • AllocatedProvisionedConcurrentExecutions (integer) --

    The amount of provisioned concurrency allocated. When a weighted alias is used during linear and canary deployments, this value fluctuates depending on the amount of concurrency that is provisioned for the function versions.

  • Status (string) --

    The status of the allocation process.

  • StatusReason (string) --

    For failed allocations, the reason that provisioned concurrency could not be allocated.

  • LastModified (string) --

    The date and time that a user last updated the configuration, in ISO 8601 format.

Exceptions

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

Examples

The following example allocates 100 provisioned concurrency for the BLUE alias of the specified function.

response = client.put_provisioned_concurrency_config(
    FunctionName='my-function',
    ProvisionedConcurrentExecutions=100,
    Qualifier='BLUE',
)

print(response)

Expected Output:

{
    'AllocatedProvisionedConcurrentExecutions': 0,
    'LastModified': '2019-11-21T19:32:12+0000',
    'RequestedProvisionedConcurrentExecutions': 100,
    'Status': 'IN_PROGRESS',
    'ResponseMetadata': {
        '...': '...',
    },
