Parser Cache: $wgParserCacheType
Parser cache setting
Introduced in version:1.5.0
Removed in version:still in use
Allowed values:(One of the cache constants) see below
Default value:CACHE_ANYTHING


Parser cache setting.

Here are the available cache constants, as defined in Defines.php

  • CACHE_ANYTHING - Use anything, as long as it works
  • CACHE_NONE - Do not cache
  • CACHE_DB - Store cache objects in the DB
  • CACHE_MEMCACHED - memcached, must specify servers in Manual:$wgMemCachedServers
  • CACHE_ACCEL - APC, or WinCache, whichever is available, in this order. Determined by the function "ObjectCache::newAccelerator".


For a very large wiki (tens of thousands of pages) value of CACHE_DB might be preferable to CACHE_MEMCACHED. Although memcached is faster, it won't be able to cache everything (no reasonable amount of memory would be enough), while DB will be. Therefore DB will have much higher percentage of cache hits.

If you set $wgMainCacheType then the values for $wgParserCacheType and $wgMessageCacheType will inherit it. If no cache choice is configured (by default $wgMainCacheType is CACHE_NONE), then CACHE_ANYTHING will forward to CACHE_DB.
