[TiDB Usage Environment] Production Environment
I would like to ask if there is a way to separately access TiKV and TiFlash. For example, deploying two TiDB servers (setting fixed access to TiFlash or TiKV) consumes too many resources. Is there any other method? The result requires two connection strings to avoid TiFlash masking SQL performance and to clearly define optimization directions.
