Amazon Aurora MySQL now supports multi-source replication, allowing a single cluster to ingest data from multiple independent MySQL sources simultaneously. This feature simplifies data consolidation for use cases like merging shards or aggregating regional data into a central reporting hub. Additionally, delayed replication enables binlog replicas to intentionally lag behind the source by a configurable duration, providing a safeguard against human error and logic bugs.
- Consolidate data from multiple MySQL shards or regional instances into one central Aurora cluster.
- Use delayed replication as a safety net to recover from accidental drops or bad updates.
- Configure lag duration on binlog replicas to create a time-window for error correction.
- Leverage multi-source replication for centralized operational workflows like reporting.
Fleet impact: For Aurora MySQL fleets, multi-source replication simplifies shard unification and centralized reporting without complex ETL pipelines. Delayed replication offers a low-effort recovery mechanism against DDL/DML errors; verify binlog retention and replica lag monitoring align with your RPO/RTO requirements.
