 # Incrementally synchronize data From Aurora MySQL to TiDB
 
 [TiDB Data Migration](https://github.com/pingcap/dm) (DM) is an integrated data migration task management platform, which supports the full data migration and the incremental data replication from MySQL-compatible databases (such as MySQL, MariaDB, and Aurora MySQL) into TiDB. It can help to reduce the operation cost of data migration and simplify the troubleshooting process.

+Using Aurora's existing snapshot mechanism is the most convenient way, but beacuse [DM](https://github.com/pingcap/dm) does not yet support the parquet format, so we need to use [Lightning](https://docs.pingcap.com/tidb/stable/tidb-lightning-overview) for full data import first, and then use [DM](https://github.com/pingcap/dm) for incremental data synchronization.
