public class ParameterGroup
extends com.pulumi.resources.CustomResource

Provides an RDS DB parameter group resource. Documentation of the available parameters for various RDS engines can be found at: * [Aurora MySQL Parameters](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/AuroraMySQL.Reference.html) * [Aurora PostgreSQL Parameters](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/AuroraPostgreSQL.Reference.html) * [MariaDB Parameters](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Appendix.MariaDB.Parameters.html) * [Oracle Parameters](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_ModifyInstance.Oracle.html#USER_ModifyInstance.Oracle.sqlnet) * [PostgreSQL Parameters](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Appendix.PostgreSQL.CommonDBATasks.html#Appendix.PostgreSQL.CommonDBATasks.Parameters) > **Hands-on:** For an example of the `aws.rds.ParameterGroup` in use, follow the Manage AWS RDS Instances tutorial on HashiCorp Learn. > **NOTE:** If you encounter a pulumi preview showing parameter changes after an apply (_i.e._, _perpetual diffs_), see the Problematic Plan Changes example below for additional guidance. ## Example Usage ### Basic Usage

             .parameters(            
                 ParameterGroupParameterArgs.builder()

                     .name("character_set_client")
                     .value("utf8")
                     .build())

             .family("mysql5.6")
             .build());
 
     }
 }

### Example of Problematic Configuration The following Terraform configuration includes a parameter that overlaps with an AWS default parameter, using the same `name` (`defaultPasswordLifetime`) and `value` (`0`). However: - AWS sets the default `applyMethod` for this parameter to `pending-reboot`. - The AWS Provider defaults all parameters' `applyMethod` to `immediate`. This configuration attempts to change _only_ the `applyMethod` from `pending-reboot` to `immediate`, which is not allowed by AWS.

 import java.nio.file.Files;
 import java.nio.file.Paths;
 
 public class App {
     public static void main(String[] args) {
         Pulumi.run(App::stack);
     }
 
     public static void stack(Context ctx) {
         var test = new ParameterGroup("test", ParameterGroupArgs.builder()
             .parameters(ParameterGroupParameterArgs.builder()
                 .name("default_password_lifetime")
                 .value("0")
                 .build())
             .name("random-test-parameter")
             .family("mysql5.7")
             .build());
 
     }
 }

### Solution 1: Remove the Default Parameter Exclude the default parameter, such as `defaultPasswordLifetime` in this example, from your configuration entirely. This ensures Terraform does not attempt to modify the parameter, leaving it with AWS's default settings.

 
 package generated_program;
 
 import com.pulumi.Context;
 import com.pulumi.Pulumi;
 import com.pulumi.core.Output;
 import com.pulumi.aws.rds.ParameterGroup;
 import com.pulumi.aws.rds.ParameterGroupArgs;
 import java.util.ArrayList;
 import java.util.Arrays;
 import java.util.Map;
 import java.io.File;
 import java.nio.file.Files;
 import java.nio.file.Paths;
 
 public class App {
     public static void main(String[] args) {
         Pulumi.run(App::stack);
     }
 
     public static void stack(Context ctx) {
         var test = new ParameterGroup("test", ParameterGroupArgs.builder()
             .name("random-test-parameter")
             .family("mysql5.7")
             .build());
 
     }
 }

### Solution 2: Modify the Parameter's Value Also Change the `value` of the parameter along with its `applyMethod`. Since the AWS default `value` is `0`, selecting any other valid value (_e.g._, `1`) will resolve the issue.

 
 package generated_program;
 
 import com.pulumi.Context;
 import com.pulumi.Pulumi;
 import com.pulumi.core.Output;
 import com.pulumi.aws.rds.ParameterGroup;
 import com.pulumi.aws.rds.ParameterGroupArgs;
 import com.pulumi.aws.rds.inputs.ParameterGroupParameterArgs;
 import java.util.ArrayList;
 import java.util.Arrays;
 import java.util.Map;
 import java.io.File;
 import java.nio.file.Files;
 import java.nio.file.Paths;
 
 public class App {
     public static void main(String[] args) {
         Pulumi.run(App::stack);
     }
 
     public static void stack(Context ctx) {
         var test = new ParameterGroup("test", ParameterGroupArgs.builder()
             .parameters(ParameterGroupParameterArgs.builder()
                 .name("default_password_lifetime")
                 .value("1")
                 .build())
             .name("random-test-parameter")
             .family("mysql5.7")
             .build());
 
     }
 }

### Solution 3: Align `applyMethod` with AWS Defaults Explicitly set the `applyMethod` to match AWS's default value for this parameter (`pending-reboot`). This prevents conflicts between Terraform's default (`immediate`) and AWS's default where the `value` is not changing.

 
 package generated_program;
 
 import com.pulumi.Context;
 import com.pulumi.Pulumi;
 import com.pulumi.core.Output;
 import com.pulumi.aws.rds.ParameterGroup;
 import com.pulumi.aws.rds.ParameterGroupArgs;
 import com.pulumi.aws.rds.inputs.ParameterGroupParameterArgs;
 import java.util.ArrayList;
 import java.util.Arrays;
 import java.util.Map;
 import java.io.File;
 import java.nio.file.Files;
 import java.nio.file.Paths;
 
 public class App {
     public static void main(String[] args) {
         Pulumi.run(App::stack);
     }
 
     public static void stack(Context ctx) {
         var test = new ParameterGroup("test", ParameterGroupArgs.builder()
             .parameters(ParameterGroupParameterArgs.builder()
                 .applyMethod("pending-reboot")
                 .name("default_password_lifetime")
                 .value("0")
                 .build())
             .name("random-test-parameter")
             .family("mysql5.7")
             .build());
 
     }
 }

## Import ### Identity Schema #### Required - `name` (String) Name of the DB parameter group. #### Optional - `accountId` (String) AWS Account where this resource is managed. - `region` (String) Region where this resource is managed. Using `pulumi import`, import DB Parameter groups using the `name`. For example: ```sh $ pulumi import aws:rds/parameterGroup:ParameterGroup example rds-pg ```
