Confluence Docs 3.0 : Confluence Cache Schemes This page last changed on Oct 16, 2008 by mryall. #### Default Scheme If a cache has not been defined, then it will use the default cache size and expiry. As the start of your `confluence/WEB-INF/classes/confluence-coherence-cache-config.xml` file you will notice the following:
    <cache-mapping>
      <cache-name>*</cache-name>
      <scheme-name>default</scheme-name>
    </cache-mapping>
So basically all caches will default to using the default scheme, which is defined as below:
    <!-- Default scheme -->
    <local-scheme>
      <scheme-name>default</scheme-name>
      <class-name>com.atlassian.confluence.cache.tangosol.ExpiryCountingLocalCache</class-name>
      <high-units>1000</high-units>
      <expiry-delay>3600</expiry-delay>
    </local-scheme>
I.e. with a size of 1000 Objects and an expiry of 3600 seconds. Other schemes use the above as their default and either override the size of the cache, or the length of the expiry. #### Common Schemes In addition to the default scheme, there are also common schemes used in Confluence caches:
    <!-- Common schemes -->
    <local-scheme>
      <scheme-name>large</scheme-name>
      <scheme-ref>default</scheme-ref>
      <high-units>10000</high-units>
    </local-scheme>
    <local-scheme>
      <scheme-name>medium</scheme-name>
      <scheme-ref>default</scheme-ref>
      <high-units>5000</high-units>
    </local-scheme>
    <local-scheme>
      <scheme-name>small</scheme-name>
      <scheme-ref>default</scheme-ref>
      <high-units>100</high-units>
    </local-scheme>
    <local-scheme>
      <scheme-name>large-transient</scheme-name>
      <scheme-ref>default</scheme-ref>
      <high-units>10000</high-units>
      <expiry-delay>300s</expiry-delay>
    </local-scheme>
    <local-scheme>
      <scheme-name>user</scheme-name>
      <scheme-ref>default</scheme-ref>
      <high-units>5000</high-units>
      <expiry-delay>300s</expiry-delay>
    </local-scheme>
