Move store related metrics to ChronicleMapStore

Do not emit all metrics from the chronicle-map cache implementation, but
rather split them so that the cache only emits cache-related metrics,
whilst the store emits storage-related ones.

This unlocks the possibility to centralize the emission of
store-related metrics regardless whether the store is accessed from
the ChronicleMapCacheImpl or the ChronicleMapCacheLoader.

Persistent cache for Gerrit, based on ChronicleMap

Non-blocking and super-fast on-disk cache libModule for Gerrit Code Review based on ChronicleMap on-disk implementation.

How to build

This libModule is built like a Gerrit in-tree plugin, using Bazelisk. See the build instructions for more details.

Setup

  • Install cache-chronicalmap module

Install the chronicle-map module into the $GERRIT_SITE/lib directory.

Add the cache-chroniclemap module to $GERRIT_SITE/etc/gerrit.config as follows:

[gerrit]
  installModule = com.googlesource.gerrit.modules.cache.chroniclemap.ChronicleMapCacheModule

For further information and supported options, refer to config documentation.
