AWS Elasticache - Global replication group is not supported for the node type

[OmarSalka]

AWS Provider version = v3.29.1

Hi,

I am not able to create a Global Replication Group. I get the following error:

Error: error creating ElastiCache Global Replication Group: InvalidParameterValue: 
Global replication group is not supported for the node type.
status code: 400, request id: xxxxxxxxxxxxxxxxxxxxxxxxxx

But I am using a supported node type cache.t3.medium aaccording to the documentation

Here is the configuration for the primary replication group:

resource "aws_elasticache_replication_group" "ae1" {
  replication_group_id          = "ae1-elasticache-test
  replication_group_description = "ae1-elasticache-test replication group"
  engine                        = "redis"
  engine_version                = "6.0.5"
  node_type                     = "cache.t3.medium"
  number_cache_clusters         = 2
  port                          = 6379
  subnet_group_name             = "subnet-group"
  security_group_ids            = [aws_security_group.redis_sg.id]
  multi_az_enabled              = true
  automatic_failover_enabled    = true
}

Also here's the configuration for the global replication group:

resource "aws_elasticache_global_replication_group" "global" {
  global_replication_group_id_suffix = "elasticache-grg-test
  primary_replication_group_id       = aws_elasticache_replication_group.ae1.id
}

tried with a cache.m4.large node type and it's still returning the same error

I went to the console and tried doing it manually and noticed the list of node types that are supported are different from the documentation. If you could update the aws documentation that would be very much appreciated

Hi @OmarSalka 👋 This project is not maintained by AWS (FAQ), however, for this type of documentation update request you can click the "Feedback" link that is present on each of the AWS documentation pages. Please also note that there is a separate page that contains Global Datastores Prerequisites and Limitations and references the required node types, that maybe could be linked.

Thanks you for sharing that link with me!
