Datacache
Besides dedicated database table structures, MyBB utilizes a data cache system. Cache entries are saved in the mybb_datacache table and propagated to configured cache store.
The following table lists default content of the Admin CP’s Tools & Maintenance → Cache Manager. Entries with Redundancy are usually created for performance improvements and can be rebuilt automatically using the database.
