db_parameters
Creates, updates, deletes, gets or lists a db_parameters resource.
Overview
| Name | db_parameters |
| Type | Resource |
| Id | aws.neptune.db_parameters |
Fields
The following fields are returned by SELECT queries:
- describe_db_parameters
| Name | Datatype | Description |
|---|---|---|
allowed_values | string | Specifies the valid range of values for the parameter. |
apply_method | string | Indicates when to apply parameter updates. |
apply_type | string | Specifies the engine specific parameters type. |
data_type | string | Specifies the valid data type for the parameter. |
description | string | Provides a description of the parameter. |
is_modifiable | 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. |
minimum_engine_version | string | The earliest engine version to which the parameter can apply. |
parameter_name | string | Specifies the name of the parameter. |
parameter_value | string | Specifies the value of the parameter. |
source | string | Indicates the source of the parameter value. |
Methods
The following methods are available for this resource:
| Name | Accessible by | Required Params | Optional Params | Description |
|---|---|---|---|---|
describe_db_parameters | select | DBParameterGroupName, region | Source, Filters, MaxRecords, Marker | Returns the detailed parameter list for a particular DB parameter group. |
copy_db_parameter_group | exec | SourceDBParameterGroupIdentifier, TargetDBParameterGroupIdentifier, TargetDBParameterGroupDescription, region | Tags | Copies the specified DB parameter group. |
reset_db_parameter_group | exec | DBParameterGroupName, region | ResetAllParameters, Parameters | Modifies the parameters of a DB parameter group to the engine/system default value. To reset specific parameters, provide a list of the following: ParameterName and ApplyMethod. To reset the entire DB parameter group, specify the DBParameterGroup name and ResetAllParameters parameters. When resetting the entire group, dynamic parameters are updated immediately and static parameters are set to pending-reboot to take effect on the next DB instance restart or RebootDBInstance request. |
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 |
|---|---|---|
DBParameterGroupName | string | The name of the DB parameter group. Constraints: Must match the name of an existing DBParameterGroup. |
SourceDBParameterGroupIdentifier | string | The identifier or ARN for the source DB parameter group. For information about creating an ARN, see Constructing an Amazon Resource Name (ARN). Constraints: Must specify a valid DB parameter group. Must specify a valid DB parameter group identifier, for example my-db-param-group, or a valid ARN. The source DB parameter group must be in the same Amazon Region as the copy. Neptune does not support cross-Region copying of parameter groups. |
TargetDBParameterGroupDescription | string | A description for the copied DB parameter group. |
TargetDBParameterGroupIdentifier | string | The identifier for the copied DB parameter group. Constraints: Cannot be null, empty, or blank. Must contain from 1 to 255 letters, numbers, or hyphens. First character must be a letter. Cannot end with a hyphen or contain two consecutive hyphens. Example: my-db-parameter-group |
region | string | AWS region (default: us-east-1) |
Filters | array | This parameter is not currently supported. |
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. |
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 | To reset the entire DB parameter group, specify the DBParameterGroup name and ResetAllParameters parameters. To reset specific parameters, provide a list of the following: ParameterName and ApplyMethod. A maximum of 20 parameters can be modified in a single request. Valid Values (for Apply method): pending-reboot |
ResetAllParameters | boolean | Specifies whether (true) or not (false) to reset all parameters in the DB parameter group to default values. Default: true |
Source | string | The parameter types to return. Default: All parameter types returned Valid Values: user | system | engine-default |
Tags | array | The tags to be assigned to the copied DB parameter group. |
