Bug Report

Please answer these questions before submitting your issue. Thanks!

What did you do? If possible, provide a recipe for reproducing the error.

Suppose we have a changefeed that needs to sync 2 tables (subtasks) running on a cdc server (capture).
After we adding a new capture, subtasks can not be balanced to the new capture.

What did you expect to see?

Subtasks are balanced to two captures evenly.

What did you see instead?

Does not balance.
