Each node of the TiDB database (TIDB-Server, TikV-Server, and PD) has its own configuration file to store customized configuration parameters. The cluster configuration refers to modify the configuration in these configuration files.

Each TIDB-Server stores its own configuration file, which is located in tidb/config/config.toml of the TIDB-Server node.
