Aurora MySQL introduced multi-source replication, enabling a single cluster to replicate from multiple source databases simultaneously, facilitating data consolidation for scenarios like shard merging or centralized reporting. Additionally, delayed replication allows configuring a replica to lag intentionally behind its source, providing a buffer against accidental data errors by enabling quick recovery without full restore procedures.
These features enhance flexibility and data protection in replication workflows. Both capabilities are available starting with Aurora MySQL version 8.4.8 and in all AWS regions offering the service. Amazon documents detailed use-cases and recovery guidance to support implementation of these replication improvements.
