RDSPostgres通过terraform将复本读取为多az 、、、 我发现了一篇关于使用RDSread replica作为多AZ的有趣文章。https://aws.amazon.com/about-aws/whats-new/2018/01/amazon-rds-read-replicas-now-support-multi-az-deployments所以我想使用Terraform来部署这个策略,但是在Terraform文档中没有任何关于部署Postgresql数据库...
Though RDS facilitates replication configuration and management, the best practices described here remain essential to minimizing replication lag. These practices also help optimize DR strategy, read workload, and healthy source instances. For more information about RDS Postgres Read Replica limitations, mo...

Specifically: Writes should always be handled by the write server (read replica connections are read-only) Reads shouldusuallybe handled by the read replicas If there is an open transaction, reads should be handled by the write connection. This ensures that whilst a transaction is open, the ap...

Aurora is “AWS cloud optimized” and claims 5x performance improvement over MySQL on RDS, over 3x the performance of Postgres on RDS Aurora storage automatically grows in increments of 10GB, up to 128 TB. Aurora can have 15 replicas while MySQL has 5, and the replication process is faster...
為保障同步延遲時間展示的準確性,DTS會在源庫中新增一個名為dts_postgres_heartbeat的心跳錶。 同步期間,DTS會在源庫中建立首碼為dts_sync_的replication slot用於複製資料。通過該replication slot,DTS可以擷取源庫15分鐘內的增量日誌。 說明 DTS釋放執行個體後會主動刪除該replication slot...
