Request Syntax

response = client.describe_db_parameters(
    DBParameterGroupName='string',
    Source='string',
    Filters=[
        {
            'Name': 'string',
            'Values': [
                'string',
            ]
        },
    ],
    MaxRecords=123,
    Marker='string'
)
Parameters
  • DBParameterGroupName (string) --

    [REQUIRED]

    The name of a specific DB parameter group to return details for.

    Constraints:

    • If supplied, must match the name of an existing DBParameterGroup.
  • Source (string) --

    The parameter types to return.

    Default: All parameter types returned

    Valid Values: user | system | engine-default

  • 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
      • 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 that you can retrieve the remaining results.

    Default: 100

    Constraints: Minimum 20, maximum 100.

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

Response Structure

  • (dict) --

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

    • Parameters (list) --

      A list of Parameter values.

      • (dict) --

        This data type is used as a request parameter in the ModifyDBParameterGroup and ResetDBParameterGroup actions.

        This data type is used as a response element in the DescribeEngineDefaultParameters and DescribeDBParameters actions.

        • ParameterName (string) --

          Specifies the name of the parameter.

        • ParameterValue (string) --

          Specifies the value of the parameter.

        • Description (string) --

          Provides a description of the parameter.

        • Source (string) --

          Indicates the source of the parameter value.

        • ApplyType (string) --

          Specifies the engine specific parameters type.

        • DataType (string) --

          Specifies the valid data type for the parameter.

        • AllowedValues (string) --

          Specifies the valid range of values for the parameter.

        • IsModifiable (boolean) --

          Indicates whether ( true ) or not ( false ) the parameter can be modified. Some parameters have security or operational implications that prevent them from being changed.

        • MinimumEngineVersion (string) --

          The earliest engine version to which the parameter can apply.

        • ApplyMethod (string) --

          Indicates when to apply parameter updates.

        • SupportedEngineModes (list) --

          The valid DB engine modes.

          • (string) --
    • 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 .

Examples

This example lists information for up to the first 20 system parameters for the specified DB parameter group.

response = client.describe_db_parameters(
    DBParameterGroupName='mymysqlparametergroup',
    MaxRecords=20,
    Source='system',
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
