Note: This description is for the 1.20.1+ versions only.
What is GriefLogger
Grieflogger is a blazing fast mod that logs player interactions like breaking and placing blocks, killing entities, dropping, picking up, breaking, consuming items, and much more!
To store all of this data, GriefLogger uses a SQLite database by default. This database is stored within the config file. You can also connect GriefLogger to a MySQL databasevia the config to make it run even faster.
All of the transactions between the mod and the database are asynchronous/multithreaded. This means that the server doesn't have to wait for the transaction to be done before continuing to run other code.
