• Filters (list) –

  This parameter isn’t currently supported.

  • (dict) –

    A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as IDs. The filters supported by a describe operation are documented with the describe operation.

    Note

    Currently, wildcards are not supported in filters.

    The following actions can be filtered:

    • DescribeDBClusterBacktracks

    • DescribeDBClusterEndpoints

    • DescribeDBClusters

    • DescribeDBInstances

    • DescribeDBRecommendations

    • DescribeDBShardGroups

    • DescribePendingMaintenanceActions

    • Name (string) – [REQUIRED]

      The name of the filter. Filter names are case-sensitive.

    • Values (list) – [REQUIRED]

      One or more filter values. Filter values are case-sensitive.

      • (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 you can retrieve the remaining results.

  Default: 100

  Constraints: Minimum 20, maximum 100.

• Marker (string) – An optional pagination token provided by a previous DescribeEngineDefaultParameters 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:

Response Structure

• (dict) –

  • EngineDefaults (dict) –

    Contains the result of a successful invocation of the DescribeEngineDefaultParameters action.
