Amazon Relational Database Service (Amazon RDS) for MySQL now supports multi-source replication, which allows you to configure multiple RDS for MySQL database instances as sources for a single RDS for MySQL target database instance. Multi-source replication on RDS for MySQL enables you to merge multiple shards into a single target, or consolidate data in one RDS for MySQL instance for analytics, or long-term backups.

For every target RDS for MySQL instance, you can configure up to 15 RDS for MySQL source database instances. For read scaling, you can configure read replicas on the multi-source replication target instance. Multi-source replication is available on RDS for MySQL versions 5.7.44, 8.0.35 and higher minor versions.
