Amazon Aurora MySQL now supports multi-source and delayed replication

feature

Amazon Aurora MySQL has added support for multi-source replication and delayed replication. Multi-source replication simplifies data consolidation from disparate MySQL databases, enabling use cases like merging shards or aggregating data for reporting and backups. Delayed replication offers a safeguard against human error or logical data corruption by allowing replicas to intentionally lag behind the source, facilitating recovery without full database restores. These features are available on Aurora MySQL version 8.4.8 and higher, across all AWS Regions where Aurora MySQL is offered.

  • Multi-source replication for data consolidation

    A single Aurora MySQL cluster can now replicate data from multiple source databases concurrently. This streamlines data consolidation from separate MySQL instances, supporting operational workflows like reporting and backups, and simplifying tasks such as merging database shards.

  • Delayed replication for enhanced data protection

    Users can configure a binlog replica to intentionally lag behind its source by a specified period. This provides a mechanism to recover from human error or logical data corruption by stopping replication before a harmful change is applied and promoting the replica, avoiding a full database restore.
