describe_replications

DatabaseMigrationService.Client.describe_replications(**kwargs)

Provides details on replication progress by returning status information for one or more provisioned DMS Serverless replications.

See also: AWS API Documentation

Request Syntax

response = client.describe_replications(
    Filters=[
        {
            'Name': 'string',
            'Values': [
                'string',
            ]
        },
    ],
    MaxRecords=123,
    Marker='string'
)

Parameters:

• Filters (list) –

  Filters applied to the replications.

  • (dict) –

    Identifies the name and value of a filter object. This filter is used to limit the number and type of DMS objects that are returned for a particular Describe* call or similar operation. Filters are used as an optional parameter for certain API operations.

    • Name (string) – [REQUIRED]

      The name of the filter as specified for a Describe* or similar operation.

    • Values (list) – [REQUIRED]

      The filter value, which can specify one or more values used to narrow the returned results.

      • (string) –

• MaxRecords (integer) – The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, a pagination token called a marker is included in the response so that the remaining results can be retrieved.

• Marker (string) – An optional pagination token provided by a previous request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.

Return type:

dict

Returns:
