Maintaining Cache Tables

l10n_cache Table

As of Mediawiki >= 1.16 contents of this table can be deleted and excluded from backups as it will be regenerated when needed.

objectcache Table

As of Mediawiki >= 1.30 the objectcache table is the default backend for the Main Stash service, and is also used by a small number of high-impact cache operations as fallback when no other cache backend is configured (e.g. Memcached). Its content can be safely deleted and excluded from backups as it will be regenerated when needed.
