RDS.Client.describe_db_parameters(**kwargs)

Returns the detailed parameter list for a particular DB parameter group.

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) –

  A filter that specifies one or more DB parameters to describe.

  The only supported filter is parameter-name. The results list only includes information about the DB parameters with these names.

  • (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 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.

Return type:

dict

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) –

        The name of the parameter.

      • ParameterValue (string) –

        The value of the parameter.

      • Description (string) –

        Provides a description of the parameter.

      • Source (string) –

        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.

Exceptions

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