Original topic: 7.4 设置某个tidbserver的引擎后所有tidbserver都会生效,不能单独设置某个实例的
Two tidbserver instances, one set as tikv, tidb and the other set as tidb, tiflash. As a result, both instances are tidb, tikv, and the individual settings for a specific instance do not take effect; the same operation works on version 7.0.
Reproduction method: Initialize two TiDB server nodes, one TiKV, and one TiFlash.

Are you going to set hit or choose an engine?
Directly set the engine of a specific tidbserver instance to the TiFlash engine.
There is no such feature.
You’re referring to this, right?
Do you mean setting the session-level tidb_isolation_read_engines
variable, but all the TiDB servers changed?
I tested it and couldn’t reproduce the issue.
The original post also verified that there seems to be a conflict between the configuration file and system variables~
So, is it a conflict between the configuration file and the system variables?
Feedback has been given to the product and research team, let’s wait for the conclusion.
Is there any progress on this?
