How to Replicate Tencent Cloud TDSQL MySQL to Standard MySQL with NineData

Tencent Cloud TDSQL MySQL is widely used for core online workloads. But once a team needs cross-cloud migration, test environment refreshes, standardized MySQL copies, or downstream data delivery, a practical question appears immediately: how do you replicate a distributed MySQL source to standard MySQL without interrupting the business?

According to the latest NineData replication matrix, TDSQL MySQL -> MySQL supports schema replication, full replication, incremental replication, and data comparison.

  • Replicating a Tencent Cloud business database into a standard MySQL environment.
  • Building continuously updated copies for testing, reporting, or read-only queries.
  • Completing a full initialization first and then catching up through incremental replication while the source is still receiving writes.

What NineData helps you do​

  • Schema replication to initialize objects automatically on the target.
  • Full replication to move the historical dataset.
  • Incremental replication to keep up with inserts, updates, and deletes through Binlog.
  • Data comparison to reduce uncertainty before cutover or acceptance.

What you need to prepare​

  • Enable Binlog on the source and set binlog_format=ROW and binlog_row_image=FULL.
  • If the source is a replica, enable log_slave_updates.
  • Make sure the target account has privileges such as CREATE, INSERT, UPDATE, and DELETE.
