Functional Differences between leveldataoverride.lua and worldgenoverride.lua?

[WH-2099]

Don't Starve Together is a really fun game and I've had a great time with many of my friends.
In order to automate the server management, I'm recently writing some scripts for assistance, and I'm currently having problems with the in-game world configuration files, so I'd like to ask for some guidance.
Currently there are two in-game world configuration files:

leveldataoverride.lua

 

worldgenoverride.lua

I can't figure out the exact functional difference between these two files.

According to Google, I found the following information.

To summarize, I could not find a clear description of the function of the files(leveldataoverride.lua and worldgenoverride.lua), and there is a blind spot as to what these two files do.
The current situation is that although it is mentioned in the official announcement that dedicated servers should use worldgenoverride.lua, many dedicated servers are using leveldataoverride.lua by default because the client only generates leveldataoverride.lua, and a large number of scripts and helpers use the practice of copying client configuration files. leveldataoverride.lua for world configuration.

Personally, I think there is a need for a detailed official feature guide for leveldataoverride.lua and worldgenoverride.lua.
If you know anything about these two documents, I would appreciate the knowledge you share.

PS: I used a translator, so I hope you understand that the expression may not be very accurate.
