Global configuration of the cache-chroniclemap libModule is done in the gerrit.config file in the site's etc directory.
Information about gerrit caches mechanism can be found in the relevant documentation section.
Chronicle-map supports most of the cache configuration parameters, such as:
maxAge: Maximum age to keep an entry in the cache. Gerrit docs
refreshAfterWrite: Duration after which we asynchronously refresh the cached value. Gerrit docs
Chronicle-map implementation however might require some additional configuration
cache.<name>.avgKeySize : The average number of bytes to be allocated for the key of this cache. If key is a boxed primitive type, a value interface or Byteable subclass, i. e. if key size is known statically, it is automatically accounted by chronicle-map. In this case, this value will be ignored.
cache.<name>.avgValueSize : The average number of bytes to be allocated for a value of this cache. If key is a boxed primitive type, a value interface or Byteable subclass, i. e. if key size is known statically, it is automatically accounted by chronicle-map. In this case, this value will be ignored.
cache.<name>.entries : The number of entries that this cache is going to hold, at most
