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

Starting today, Amazon Aurora MySQL supports two new replication capabilities: multi-source replication and delayed replication. Multi-source replication lets a single Aurora MySQL cluster replicate from multiple source databases at the same time, making it easier to consolidate data from separate MySQL databases. This enables critical use-cases, such as merging shards or aggregating data from separate databases (e.g. regional or departmental instances) into a central location for operational workflows, such as reporting and backups. To learn more, please refer to the [MySQL multi-source replication documentation](https://dev.mysql.com/doc/refman/8.4/en/replication-multi-source.html). Delayed replication lets you configure a binlog replica to intentionally lag behind its source by a set period of time, giving you a simple safeguard against human error and logical data corruption. If a harmful change is made on the source, you can recover quickly by stopping replication to the replica before the change is applied and promoting it, without performing a full database restore. A delayed replica also provides a convenient fallback during upgrades and a way to inspect an earlier state of your data. To learn more, please refer to the [MySQL delayed replication documentation](https://dev.mysql.com/doc/refman/8.4/en/replication-delayed.html). Together, these capabilities give you greater flexibility and stronger data protection when replicating into Aurora MySQL. Multi-source replication and Delayed replication are supported on Aurora MySQL version 8.4.8 and higher, in all [AWS Regions](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Concepts.RegionsAndAvailabilityZones.html#Aurora.Overview.Availability.MySQL) where Aurora MySQL is available. For additional information on Aurora MySQL disaster recovery, see the [guidance from our solutions library](https://docs.aws.amazon.com/solutions/disaster-recovery-using-amazon-aurora/). To learn more, please refer to [Aurora MySQL 8.4](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraMySQLReleaseNotes/AuroraMySQL.Updates.84Updates.html) release notes. [Amazon Aurora](https://aws.amazon.com/rds/aurora/) is designed for high performance and availability at global scale with full MySQL compatibility. It provides scale-to-zero serverless compute, Aurora Global Database for multi-Region resilience, Aurora I/O-Optimized for improved price performance on I/O-intensive workloads, and built-in security and continuous backups.
