Description

DynamoDB Global Tables v2 are configured using the "replica" blocks in the "aws_dynamodb_table" resource. The replicas are then created automatically in the specified regions.

The problem is that with the current configuration it is not possible to set the "point_in_time_recovery" on the replicas. The replica tables are always created as "disabled", irrespective of the aws_dynamodb_table configuration.

It can probably be supported by using "null_resources" but ideally it should be part of the replica configuration.

The ability to configure KMS keys and tags in the replicas has already been implemented as per the links on the Reference section. Cloudformation also allows point_in_time_recovery to be configured per replica.

Affected Resource(s)

• aws_dynamodb_table

Potential Terraform Configuration

resource "aws_dynamodb_table" "some-table" {
  name = "some-table"
  billing_mode = "PAY_PER_REQUEST"
  hash_key = "some-key"
  stream_enabled = true
  stream_view_type = "NEW_AND_OLD_IMAGES"

  attribute {
    name = "some-key"
    type = "S"
  }

  point_in_time_recovery {
    enabled = true
  }

  replica {
    region_name = "eu-west-2"
    point_in_time_recovery {
      enabled = true
    }
  }
}
