Each server type in `TiDB` cluster (`TiDB` server, `TiKV` server, and `PD` server) has its own configuration file to keep the node specific cluster parameters. 

For `TiDB` server, it is located in `{deploy_dir}/conf/tidb.toml` on `TiDB` nodes. Please refer to: https://docs.pingcap.com/tidb/stable/tidb-configuration-file

For `TiKV` server, it is located in `{deploy_dir}/config/tikv.toml` on `TiKV` nodes. Please refer to: https://docs.pingcap.com/tidb/stable/tikv-configuration-file

For `PD` server, it is located in `{deploy_dir}/conf/pd.toml` on `Placement Driver (PD)` nodes. Please refer to: https://docs.pingcap.com/tidb/stable/pd-configuration-file
