As mentioned, after a few hours, I found that the regions shown by show table regions had changed, even though there were no data insertions or modifications, only queries. Are regions dynamically changing? Is there any rule for this?

Inserts, deletions, load imbalance, region heartbeat timeouts, etc., will all change the position, number, and size.

Is it possible to modify the configuration to disable region rebalancing?

You can manually modify region distribution and other information using pd-ctl. For details, you can refer to the documentation:

It contains the command parameters for region.

It changes in real-time, and users do not need to worry about the specific location.
