Amazon Relational Database Service (Amazon RDS) now supports replication filters for MySQL and MariaDB instances. Replication filters specify which databases and tables are replicated in a read replica. Customers create lists of databases and tables to include or exclude for each replica.
Replication filtering can reduce the size of read replicas by excluding unnecessary databases or tables, or can benefit security and compliance by excluding databases or tables from a replica. Customers can also use replication filtering to create replicas tailored to specific use cases like analytics or sharding, or to create replicas with different tables or databases in different AWS Regions.
