db_parameter_groups

Creates, updates, deletes, gets or lists a db_parameter_groups resource.

Overview

Name	db_parameter_groups
Type	Resource
Id	aws.neptune.db_parameter_groups

Fields

The following fields are returned by SELECT queries:

describe_db_parameter_groups

Name	Datatype	Description
db_parameter_group_arn	string	The Amazon Resource Name (ARN) for the DB parameter group.
db_parameter_group_family	string	Provides the name of the DB parameter group family that this DB parameter group is compatible with.
db_parameter_group_name	string	Provides the name of the DB parameter group.
description	string	Provides the customer-specified description for this DB parameter group.

Methods

The following methods are available for this resource:

Name	Accessible by	Required Params	Optional Params	Description
describe_db_parameter_groups	select	region	DBParameterGroupName, Filters, MaxRecords, Marker	Returns a list of DBParameterGroup descriptions. If a DBParameterGroupName is specified, the list will contain only the description of the specified DB parameter group.
create_db_parameter_group	insert	DBParameterGroupName, DBParameterGroupFamily, region	Description, Tags	Creates a new DB parameter group. A DB parameter group is initially created with the default parameters for the database engine used by the DB instance. To provide custom values for any of the parameters, you must modify the group after creating it using ModifyDBParameterGroup. Once you've created a DB parameter group, you need to associate it with your DB instance using ModifyDBInstance. When you associate a new DB parameter group with a running DB instance, you need to reboot the DB instance without failover for the new DB parameter group and associated settings to take effect. After you create a DB parameter group, you should wait at least 5 minutes before creating your first DB instance that uses that DB parameter group as the default parameter group. This allows Amazon Neptune to fully complete the create action before the parameter group is used as the default for a new DB instance. This is especially important for parameters that are critical when creating the default database for a DB instance, such as the character set for the default database defined by the character_set_database parameter. You can use the Parameter Groups option of the Amazon Neptune console or the DescribeDBParameters command to verify that your DB parameter group has been created or modified.
modify_db_parameter_group	update	DBParameterGroupName, region	Parameters	Modifies the parameters of a DB parameter group. To modify more than one parameter, submit a list of the following: ParameterName, ParameterValue, and ApplyMethod. A maximum of 20 parameters can be modified in a single request. Changes to dynamic parameters are applied immediately. Changes to static parameters require a reboot without failover to the DB instance associated with the parameter group before the change can take effect. After you modify a DB parameter group, you should wait at least 5 minutes before creating your first DB instance that uses that DB parameter group as the default parameter group. This allows Amazon Neptune to fully complete the modify action before the parameter group is used as the default for a new DB instance. This is especially important for parameters that are critical when creating the default database for a DB instance, such as the character set for the default database defined by the character_set_database parameter. You can use the Parameter Groups option of the Amazon Neptune console or the DescribeDBParameters command to verify that your DB parameter group has been created or modified.
delete_db_parameter_group	delete	DBParameterGroupName, region		Deletes a specified DBParameterGroup. The DBParameterGroup to be deleted can't be associated with any DB instances.

Parameters

Parameters can be passed in the WHERE clause of a query. Check the Methods section to see which parameters are required or optional for each operation.

Name	Datatype	Description
DBParameterGroupFamily	string	The DB parameter group family name. A DB parameter group can be associated with one and only one DB parameter group family, and can be applied only to a DB instance running a database engine and engine version compatible with that DB parameter group family.
DBParameterGroupName	string	The name of the DB parameter group. Constraints: Must be the name of an existing DB parameter group You can't delete a default DB parameter group Cannot be associated with any DB instances
region	string	AWS region (default: us-east-1)
DBParameterGroupName	string	The name of a specific DB parameter group to return details for. Constraints: If supplied, must match the name of an existing DBClusterParameterGroup.
Description	string	The description for the DB parameter group.
Filters	array	This parameter is not currently supported.
Marker	string	An optional pagination token provided by a previous DescribeDBParameterGroups request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.
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. Default: 100 Constraints: Minimum 20, maximum 100.
Parameters	array	An array of parameter names, values, and the apply method for the parameter update. At least one parameter name, value, and apply method must be supplied; subsequent arguments are optional. A maximum of 20 parameters can be modified in a single request. Valid Values (for the application method): immediate | pending-reboot You can use the immediate value with dynamic parameters only. You can use the pending-reboot value for both dynamic and static parameters, and changes are applied when you reboot the DB instance without failover.
Tags	array	The tags to be assigned to the new DB parameter group.

SELECT examples

describe_db_parameter_groups
