Timed Memory Cache Provider

The Timed Memory cache provider implements a local memory-only cache for dotCMS which automatically evicts items from the cache after a configured timeout period. For more information on cache providers in dotCMS, see the Cache Chaining documentation.

The functionality provided by the TimedCacheProvider has been rolled into the standard CaffineCacheProvider - you can set a TTL of any cache region using the same syntax as below.

The following parameters in the configuration properties control the bahavior of the Timed Memory cache.

Cache Timeout Properties#

The timeout used for each cache region is configured via properties of the following form:

cache.CACHE-REGION-NAME.seconds=TIMEOUT

Where:

• CACHE-REGION-NAME specifies the name of the cache region.
  • See Cache Region Names in the Cache Chaining documentation for an explanation of how to find the property names for different cache regions.
• TIMEOUT is specified in seconds.

Default Timeout#

The cache.default.seconds property specifies the default timeout. This timeout will be used for any cache region which does not have its own timeout property configured.

cache.default.seconds=100

Cache Chain Properties#

For dotCMS to use the Timed Cache provider, you must add com.dotmarketing.business.cache.provider.timedcache.TimedCacheProvider to the cache chain properties for the cache regions where you wish to use it. For example, to change the default chain to search the Timed Cache before the H22 Cache, change the default chain as follows:

cache.default.chain=com.dotmarketing.business.cache.provider.timedcache.TimedCacheProvider,com.dotmarketing.business.cache.provider.h22.H22Cache

For more information on how to configure cache regions to use the Timed Cache provider, see the Cache Chaining documentation.
