DynamoDB / Client / batch_execute_statement

batch_execute_statement

DynamoDB.Client.batch_execute_statement(**kwargs)

This operation allows you to perform batch reads or writes on data stored in DynamoDB, using PartiQL. Each read statement in a BatchExecuteStatement must specify an equality condition on all key attributes. This enforces that each SELECT statement in a batch returns at most a single item.

Note

The entire batch must consist of either read statements or write statements, you cannot mix both in one batch.

Warning

A HTTP 200 response does not mean that all statements in the BatchExecuteStatement succeeded. Error details for individual statements can be found under the Error field of the BatchStatementResponse for each statement.

Parameters:

• Statements (list) –

  [REQUIRED]

  The list of PartiQL statements representing the batch to run.

  • (dict) –

    A PartiQL batch statement request.

    • Statement (string) – [REQUIRED]

      A valid PartiQL statement.

    • Parameters (list) –

      The parameters associated with a PartiQL statement in the batch request.

      • (dict) –

        Represents the data for an attribute.

        Each attribute value is described as a name-value pair. The name is the data type, and the value is the data itself.

        For more information, see Data Types in the Amazon DynamoDB Developer Guide.

          "N": "123.45"

          Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.

          "NS": ["42.2", "-19", "7.5", "3.14"]

          Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.

          • (string) –

        • BS (list) –

          An attribute of type Binary Set. For example:

          An attribute of type Boolean. For example:

          "BOOL": true

    • ConsistentRead (boolean) –

      The read consistency of the PartiQL batch request.

• ReturnConsumedCapacity (string) –

  Determines the level of detail about either provisioned or on-demand throughput consumption that is returned in the response:

  • INDEXES - The response includes the aggregate ConsumedCapacity for the operation, together with ConsumedCapacity for each table and secondary index that was accessed. Note that some operations, such as GetItem and BatchGetItem, do not access any indexes at all. In these cases, specifying INDEXES will only return ConsumedCapacity information for table(s).

  • TOTAL - The response includes only the aggregate ConsumedCapacity for the operation.

  • NONE - No ConsumedCapacity details are included in the response.

Return type:

dict

Returns:
