◦ https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/zero-etl.settin g-up.html ▪ Aurora zero-ETL integrations with Amazon Redshift require specific values for the DB cluster parameters that control replication. Specifically, Aurora MySQL requires enhanced binlog (aurora_enhanced_binlog), and Aurora PostgreSQL requires enhanced logical replication (aurora.enhanced_logical_replication). 11
◦ 前掲リンク ▪ Enabling enhanced logical replication (aurora.enhanced_logical_replication) automatically sets the REPLICA IDENTITY parameter to FULL, which means that all column values are written to the write ahead log (WAL). This will increase the IOPS for your source DB cluster. ◦ Logical Replication : DB/テーブル単位でレプリケーション ▪ Publication / Subscription 形式の論理レプリケーション ◦ Publication の際 WAL からの変換処理を効率化する? ▪ やはりストレージ層で Redshift へデータ転送? 15
