batch_execute_statement#

RDSDataService.Client.batch_execute_statement(**kwargs)#

Runs a batch SQL statement over an array of data.

You can run bulk update and insert operations for multiple records using a DML statement with different parameter sets. Bulk operations can provide a significant performance improvement over individual insert and update operations.

Note

If a call isn’t part of a transaction because it doesn’t include the transactionID parameter, changes that result from the call are committed automatically.

There isn’t a fixed upper limit on the number of parameter sets. However, the maximum size of the HTTP request submitted through the Data API is 4 MiB. If the request exceeds this limit, the Data API returns an error and doesn’t process the request. This 4-MiB limit includes the size of the HTTP headers and the JSON notation in the request. Thus, the number of parameter sets that you can include depends on a combination of factors, such as the size of the SQL statement and the size of each parameter set.

The response size limit is 1 MiB. If the call returns more than 1 MiB of response data, the call is terminated.

Parameters:

  • resourceArn (string) –

    [REQUIRED]

    The Amazon Resource Name (ARN) of the Aurora Serverless DB cluster.

  • secretArn (string) –

    [REQUIRED]

    The ARN of the secret that enables access to the DB cluster. Enter the database user name and password for the credentials in the secret.

    For information about creating the secret, see Create a database secret.

    Note

    Currently, the schema parameter isn’t supported.

  • parameterSets (list) –

    The parameter set for the batch operation.

    The SQL statement is executed as many times as the number of parameter sets provided. To execute a SQL statement with no parameters, use one of the following options:

    • Specify one or more empty parameter sets.

    • Use the ExecuteStatement operation instead of the BatchExecuteStatement operation.

    Note

    Array parameters are not supported.
