Description

Today you can create an aws_elasticache_parameter_group to a replication_group but once you connect to a global datastore you lose all control of parameters from terraform.

Please allow configuring a aws_elasticache_global_parameter_group (or aws_elasticache_parameter_group with a optional flag) so that can be assigned to a global datastore.

Thank you.

Affected Resource(s) and/or Data Source(s)

aws_elasticache_parameter_group
aws_elasticache_global_replication_group

Potential Terraform Configuration

resource "aws_elasticache_global_parameter_group" "global" {
  name        = "cache-params"
  family      = "redis7"

  parameter {
    name = "activerehashing"
    value = "yes"
  }
}

References

I wasn't able to see an API / sdk reference to this resource. I'll have to dig further though. That would be a dependency that would need to be fulfilled before this could be completed.

Would you like to implement a fix?

None
