Amazon Aurora MySQL now supports multi-source replication and delayed replication

News

This article announces that Amazon Aurora MySQL now supports multi-source replication and delayed replication capabilities.

  • Multi-source replication allows a single Aurora MySQL cluster to replicate from multiple source databases simultaneously
  • Enables data consolidation use-cases such as merging shards or aggregating regional/departmental databases
  • Delayed replication lets replicas intentionally lag behind sources to protect against human error and logical data corruption
  • Delayed replicas provide quick recovery without full database restore and serve as fallback during upgrades
  • Both features available on Aurora MySQL 8.4.8 and higher across all AWS Regions

These replication enhancements provide greater flexibility and stronger data protection for Aurora MySQL deployments.
