Is there an existing issue for the same tech request?

  • I have checked the existing issues.

Does this tech request not affect user experience?

  • This tech request doesn't affect user experience.

What would you like to be added ?

We need to do column pruning for joins which are implicitly spawned by DML.

Why is this needed ?

Currently DML spawned joins don't do column pruning. It causes memory issues, such as matrixorigin/MO-Cloud#1531
