Table / Action / update

update#

DynamoDB.Table.update(**kwargs)#

Modifies the provisioned throughput settings, global secondary indexes, or DynamoDB Streams settings for a given table.

Warning

For global tables, this operation only applies to global tables using Version 2019.11.21 (Current version).

You can only perform one of the following operations at once:

Modify the provisioned throughput settings of the table.
Remove a global secondary index from the table.
Create a new global secondary index on the table. After the index begins backfilling, you can use UpdateTable to perform other operations.

UpdateTable is an asynchronous operation; while it’s executing, the table status changes from ACTIVE to UPDATING. While it’s UPDATING, you can’t issue another UpdateTable request. When the table returns to the ACTIVE state, the UpdateTable operation is complete.

Parameters:

AttributeDefinitions (list) –
An array of attributes that describe the key schema for the table and indexes. If you are adding a new global secondary index to the table, AttributeDefinitions must include the key element(s) of the new index.
- (dict) –
  
  Represents an attribute for describing the schema for the table and indexes.
  - AttributeName (string) – [REQUIRED]
    
    A name for the attribute.

    - B - the attribute is of type Binary
BillingMode (string) –
Controls how you are charged for read and write throughput and how you manage capacity. When switching from pay-per-request to provisioned capacity, initial provisioned capacity values must be set. The initial provisioned capacity values are estimated based on the consumed read and write capacity of your table and global secondary indexes over the past 30 minutes.
- PROVISIONED - We recommend using PROVISIONED for predictable workloads. PROVISIONED sets the billing mode to Provisioned capacity mode.
- PAY_PER_REQUEST - We recommend using PAY_PER_REQUEST for unpredictable workloads. PAY_PER_REQUEST sets the billing mode to On-demand capacity mode.
ProvisionedThroughput (dict) –
The new provisioned throughput settings for the specified table or index.
- ReadCapacityUnits (integer) – [REQUIRED]
  
  The maximum number of strongly consistent reads consumed per second before DynamoDB returns a ThrottlingException. For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide.

        If read/write capacity mode is PAY_PER_REQUEST the value is set to 0.
    - OnDemandThroughput (dict) –
      
      Updates the maximum number of read and write units for the specified global secondary index. If you use this parameter, you must specify MaxReadRequestUnits, MaxWriteRequestUnits, or both.
      - MaxReadRequestUnits (integer) –
        
        Maximum number of read request units for the specified table.
        
        To specify a maximum OnDemandThroughput on your table, set the value of MaxReadRequestUnits as greater than or equal to 1. To remove the maximum OnDemandThroughput that is currently set on your table, set the value of MaxReadRequestUnits to -1.

        Maximum number of write request units for the specified table.
        
        To specify a maximum OnDemandThroughput on your table, set the value of MaxWriteRequestUnits as greater than or equal to 1. To remove the maximum OnDemandThroughput that is currently set on your table, set the value of MaxWriteRequestUnits to -1.
  - Create (dict) –
    
    The parameters required for creating a global secondary index on an existing table:
    - IndexName
    - KeySchema
    - AttributeDefinitions
    - Projection
    - ProvisionedThroughput
    - IndexName (string) – [REQUIRED]
      
      The name of the global secondary index to be created.
    - KeySchema (list) – [REQUIRED]
      
      The key schema for the global secondary index.
      - (dict) –
        
        Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.
        
        A KeySchemaElement represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one KeySchemaElement (for the partition key). A composite primary key would require one KeySchemaElement for the partition key, and another KeySchemaElement for the sort key.
        
        A KeySchemaElement must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map.
        
        AttributeName (string) – [REQUIRED]
        
        The name of a key attribute.
        
        KeyType (string) – [REQUIRED]
        
        The role that this key attribute will assume:
        
        HASH - partition key
        
        RANGE - sort key
        
        Note
        The partition key of an item is also known as its hash attribute. The term “hash attribute” derives from DynamoDB’s usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.
        
        The sort key of an item is also known as its range attribute. The term “range attribute” derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.
    - Projection (dict) – [REQUIRED]
      
      Represents attributes that are copied (projected) from the table into an index. These are in addition to the primary key attributes and index key attributes, which are automatically projected.
      - ProjectionType (string) –
        
        The set of attributes that are projected into the index:
        
        KEYS_ONLY - Only the index and primary keys are projected into the index.
        
        INCLUDE - In addition to the attributes described in KEYS_ONLY, the secondary index will include other non-key attributes that you specify.
        
        ALL - All of the table attributes are projected into the index.
        
        When using the DynamoDB console, ALL is selected by default.
      - NonKeyAttributes (list) –
        
        Represents the non-key attribute names which will be projected into the index.
        
        For local secondary indexes, the total count of NonKeyAttributes summed across all of the local secondary indexes, must not exceed 100. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.
        
        (string) –
    - ProvisionedThroughput (dict) –
      
      Represents the provisioned throughput settings for the specified global secondary index.
      
      For current minimum and maximum provisioned throughput values, see Service, Account, and Table Quotas in the Amazon DynamoDB Developer Guide.
      - ReadCapacityUnits (integer) – [REQUIRED]
        
        The maximum number of strongly consistent reads consumed per second before DynamoDB returns a ThrottlingException. For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide.
        
        If read/write capacity mode is PAY_PER_REQUEST the value is set to 0.
      - WriteCapacityUnits (integer) – [REQUIRED]
        
        The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException. For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide.
        
        If read/write capacity mode is PAY_PER_REQUEST the value is set to 0.
    - OnDemandThroughput (dict) –
      
      The maximum number of read and write units for the global secondary index being created. If you use this parameter, you must specify MaxReadRequestUnits, MaxWriteRequestUnits, or both.
      - MaxReadRequestUnits (integer) –
        
        Maximum number of read request units for the specified table.
        
        To specify a maximum OnDemandThroughput on your table, set the value of MaxReadRequestUnits as greater than or equal to 1. To remove the maximum OnDemandThroughput that is currently set on your table, set the value of MaxReadRequestUnits to -1.
      - MaxWriteRequestUnits (integer) –
        
        Maximum number of write request units for the specified table.
        
        To specify a maximum OnDemandThroughput on your table, set the value of MaxWriteRequestUnits as greater than or equal to 1. To remove the maximum OnDemandThroughput that is currently set on your table, set the value of MaxWriteRequestUnits to -1.
  - Delete (dict) –
    
    The name of an existing global secondary index to be removed.
    - IndexName (string) – [REQUIRED]
      
      The name of the global secondary index to be deleted.
StreamSpecification (dict) –
Represents the DynamoDB Streams configuration for the table.

- StreamEnabled (boolean) – [REQUIRED]
  
  Indicates whether DynamoDB Streams is enabled (true) or disabled (false) on the table.
- StreamViewType (string) –
  
  When an item in the table is modified, StreamViewType determines what information is written to the stream for this table. Valid values for StreamViewType are:
  - KEYS_ONLY - Only the key attributes of the modified item are written to the stream.
  - NEW_IMAGE - The entire item, as it appears after it was modified, is written to the stream.
  - OLD_IMAGE - The entire item, as it appeared before it was modified, is written to the stream.
  - NEW_AND_OLD_IMAGES - Both the new and the old item images of the item are written to the stream.
SSESpecification (dict) –
The new server-side encryption settings for the specified table.
- Enabled (boolean) –
  
  Indicates whether server-side encryption is done using an Amazon Web Services managed key or an Amazon Web Services owned key.

A list of replica update actions (create, delete, or update) for the table.

Note
For global tables, this property only applies to global tables using Version 2019.11.21 (Current version).
- (dict) –
  
  Represents one of the following:
  - A new replica to be added to an existing regional table or global table. This request invokes the CreateTableReplica action in the destination Region.
  - New parameters for an existing replica. This request invokes the UpdateTable action in the destination Region.
  - An existing replica to be deleted. The request invokes the DeleteTableReplica action in the destination Region, deleting the replica and all if its items in the destination Region.
