System variables and related CLI options are missing all required information and their default values

[likidu]

Regarding system variables, I dont see any document which covers all required information about the system variables and their default values. Today I managed to find one but again that is also not very detailed and not covering all the system variables

https://docs.pingcap.com/tidb/stable/command-line-flags-for-tidb-configuration

Can we please make it more informative ?

Just to make it more clear as what I am trying to convey, if you see the document below on MySQL on the same topic, it covers in-depth details and all available variables

https://dev.mysql.com/doc/refman/8.4/en/server-system-variables.html

This page https://docs.pingcap.com/tidb/stable/system-variables provides all the available TiDB system variables with detailed information.
