describe_replication_table_statistics#

DatabaseMigrationService.Client.describe_replication_table_statistics(**kwargs)#

Returns table and schema statistics for one or more provisioned replications that use a given DMS Serverless replication configuration.

Request Syntax

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

Parameters:

ReplicationConfigArn (string) –
[REQUIRED]

The replication config to describe.
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.
Filters (list) –
Filters applied to the replication table statistics.
- (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) –

Return type:

dict
