AWS CLIも同じエラーが出る

Instance classが怪しいので serverless にしてみる

aws_rds_clusterの engine_mode, serverlessv2_scaling_configuration を追加

resource "aws_rds_cluster" "rds" {

}

instance_class を db.t4g.medium から db.serverless に変更する
performance_insights_enabled を true に変更して terraform apply 実行

resource "aws_rds_cluster_instance" "rds_instances" {
  count                           = 2
  cluster_identifier              = aws_rds_cluster.rds.id

  instance_class                  = var.instance_class # -> db.serverless
  engine                          = aws_rds_cluster.rds.engine
  engine_version                  = aws_rds_cluster.rds.engine_version
  performance_insights_enabled    =true

うまくいった模様

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  ~ update in-place

Terraform will perform the following actions:

  # module.database.aws_rds_cluster_instance.rds_instances[0] will be updated in-place
  ~ resource "aws_rds_cluster_instance" "rds_instances" {
        id                                    = "rds-0"
      ~ instance_class                        = "db.t4g.medium" -> "db.serverless"
      ~ performance_insights_enabled          = false -> true
        tags                                  = {}
        # (27 unchanged attributes hidden)
    }

  # module.database.aws_rds_cluster_instance.rds_instances[1] will be updated in-place
  ~ resource "aws_rds_cluster_instance" "rds_instances" {

performance_insights が対応しているかどうかの確認

Aurora MySQL 5.7, db.t4g.medium で有効化できている

木村明仁木村明仁

Aurora MySQL 8.0, db.t4g.medium で新規に作成するも Performance Insights 未サポートのエラーが出る
→ in-place upgrade は関係なく，Performance Insights と， Aurora MySQLバージョン， instance class の組み合わせで起きる模様

サポートに問い合わせ中

不具合である回答もらった

現状 db.t4g と Aurora MySQL 3.02.x の組み合わせでは Performance Insights が有効化できない状況

回避策
インスタンスタイプを変更してin-place upgradeする必要あり

木村明仁木村明仁

サポートから補足

将来的に Aurora MySQL の最新バージョンにて Performance Insights が使用できるインスタンスクラスが変更される可能性があるかもしれませんため、他のインスタンスクラスに変更して再実行してもメッセージが表示される場合にはお手数でございますが、以下の英語版ドキュメントの "Instance class restrictions" の箇所をご確認いただくようお願いいたします。
