[Encountered Issues: Issue Phenomenon and Impact] Currently, the TiDB cluster has 3 PDs, 3 TiDBs, 3 TiKVs, and 2 TiFlashes.
We are planning to expand the cluster by adding one TiDB server and one TiKV server.
Questions:
- What impact will there be if the CPU model of the new physical machine for expansion is different from the existing TiKV cluster’s CPU model?
- Are there any limitations on the number and ratio of TiDB, TiKV, and TiFlash after expansion?
