I understand that DM is [Dumpling] + [TiDB Lightning] and Dumpling is mydumper. So how can I determine the version of the embedded mydumper?

DM is TiDB’s data migration tool, full name is Data Migration, used for migrating both full and incremental data.
Dumpling is TiDB’s logical export tool, which is different from mydumper. TiDB also has a modified version of mydumper.
To check the tool’s version, use --version or -V.
For example, to check dumpling’s version: ./dumpling -V

Starting from v7.5.0, Mydumper has been deprecated, and most of its functions have been replaced by Dumpling. Note that it is a replacement, not an integration.

This is probably what you’re looking for.

DM and [Dumpling] + [TiDB Lightning] are unrelated; DM is a migration and synchronization component. Dumpling is a revised version of mydumper, which is now deprecated.

mydumper has been deprecated, use dumpling instead. Using mydumper with large amounts of data can cause the TiDB server to run out of memory.

These are two different components. If you are using the new version of TiDB, just forget about mydumper.

To check the version of an executable file in Linux, you generally use the parameter -v (or possibly uppercase V), or --version.

The original poster’s understanding is somewhat incorrect; mydumper has already been deprecated.
