| Configuration |
| ============= |
| |
| 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](https://charm.cs.illinois.edu/gerrit/Documentation/config-gerrit.html#cache). |
| |
| Chronicle-map supports most of the cache configuration parameters, such as: |
| |
| * `maxAge`: Maximum age to keep an entry in the cache. |
| [Gerrit docs](https://gerrit-review.googlesource.com/Documentation/config-gerrit.html#cache.name.maxAge) |
| |
| * `refreshAfterWrite`: Duration after which we asynchronously refresh the cached value. |
| [Gerrit docs](https://gerrit-review.googlesource.com/Documentation/config-gerrit.html#cache.name.refreshAfterWrite) |
| |
| Chronicle-map implementation however might require some additional configuration |
| |
| ## Configuration parameters |
| |
| ```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. |
