v1.6.0

Add `parameter_group_name_prefix_enabled` variable. Update examples and tests @aknysh (#179)

what

• Add parameter_group_name_prefix_enabled variable (defaults to true to maintain the current functionality)
• Allow using both the name and name_prefix attributes in aws_rds_cluster_parameter_group and aws_db_parameter_group resources
• Update tests to the latest versions
• Update examples to use the corerct combinations of DB instance classes and DB engine versions

why

• Allow updating old Aurora clusters, which were provisioned with the old versions of the module, to the latest version of the module without rebooting the DB instances. Old clusters, provisioned with the old versions of the module, use the name attribute (which was the only option in the old versions of the module) instead of name_prefix attribute
• Updating the parameter group causes the DB instance to reboot, which could cause a downtime. Depending on the size of the database, the downtime could take some amount of time not suitable for production clusters (after reboot, the database will go through all the recovery points and logs, and depending on the database size, it could take some time)

When you associate a new DB parameter group with a DB instance, 
the modified static and dynamic parameters are applied only after the DB instance is rebooted. 
However, if you modify dynamic parameters in the DB parameter group after you associate it with the DB instance, 
these changes are applied immediately without a reboot.

v1.4.0

Support for Activity Stream added @ngoyal16 (#159)

what

• Allow to create Activity Stream for RDS Cluster

Added by @Nuru:

• Move PostgreSQL testing to proper test region (us-east-2)
• Fix expected subnet CIDR due to fewer availability zones in us-east-2 than us-east-1
• Increase test parallelism so that tests complete in under 60 minutes

why

• Can be used to enable and activity stream from the cluster module itself

v1.3.2

🚀 Enhancements

Fix: InvalidParameterValue: CreateDBInstance error when creating non-aurora multi a-z rds cluster and aws provider update @matharoo (#149)

what

• For a multi a-z rds cluster skip creating aws_rds_cluster_instance resource when engine type is NOT aurora, aurora-mysql, aurora-postgresql
• AWS provider has a bug that is causing the terraform apply to fail due to a missing rebooting state. I have a PR merged with terraform-aws-provider that fixes it and will be included in the next release 4.23.0.
  • hashicorp/terraform-provider-aws#25718

why

• Prevent terraform from crashing when creating a non-aurora multi a-z cluster.
• aws provider update for fixing rebooting state when creating multi a-z cluster.

• closes #148
• hashicorp/terraform-provider-aws#25718

v1.3.1

🚀 Enhancements

Fix: Upgrading DB version fails with InvalidParameterCombination for instance parameter group @addavid (#151)

what

• Pass a value to db_instance_parameter_group_name argument when allow_major_version_upgrade is true.

why

• When absent, the upgrade process would fail with InvalidParameterCombination exception thrown from AWS provider.

references

• closes #134
• Terraform aws_rds_cluster resource documentation

v1.3.0

Fix missing required db_cluster_instance_class variable for multi a-z rds cluster @matharoo (#147)

what

• Adding missing required db_cluster_instance_class variable when creating a provisioned multi a-z rds cluster.

why

• Prevent failure when doing a terraform apply to create the multi a-z rds cluster.

references

• Closes #146

v1.2.1

🚀 Enhancements

Resolve Invalid count argument errors by accepting zone_id as a list @woz5999 (#144)

what

• Support a list for zone_id
• Retain legacy support for a string zone_id

why

• Resolve Invalid count argument errors when the zone doesn't exist yet
• This is the same logic from the redis module and it works well: https://github.com/cloudposse/terraform-aws-elasticache-redis/blob/master/variables.tf

v1.2.0

allow traffic inside security group @kevcube (#145)

boolean flag to enable intra-security group communication.

why

• we create our app infrastructure beginning with the database, then we use the output security group ID that gets created by Postgres as an input in our application, to give it database access
• previously what we've done is create the database, create the app, and add the app security group to the database's inputs, but this makes circular dependencies because our app depends on other outputs of the database

v1.1.0

Support for storage variables @matharoo (#141)

what

• Add support for storage variables storage_type, iops and allocated_storage.
• Fix broken tests

why

• Be able to specify the size and type of storage of the database in the cluster.

v1.0.0 Aurora Serverless V2 support @topikachu

This release adds Aurora Serverless V2 support thanks to @topikachu.

The v1.0.0 designation is not especially significant. It is part of Cloud Posse's general policy to convert to production Semantic Versioning as we make updates to relatively mature modules.

Add aurora serverlessv2 support @topikachu (#138)

what

• Add aurora serverlessv2 support

why

• AWS releases aurora serverless v2.
• Adopt this new feature in this rds cluster module
