TiDB Data Migration Platform

TiDB Data Migration (DM) is an integrated data migration task management platform that supports full data migration and incremental data replication from MySQL/MariaDB into TiDB. It helps reduce the operations cost and simplify the troubleshooting process.

Building

To check the code style and build binaries, you can simply run:

make build

Note that DM supports building with Go version Go >= 1.16, and unit test preparation can be found in Running/Unit Test

If you only want to build binaries, you can run:

make dm-worker  # build DM-worker

make dm-master  # build DM-master

make dmctl      # build dmctl

When DM is built successfully, you can find binaries in the bin directory.
