Skip unnecessary auto-adjustments of caches

Auto-adjusting the caches is an expensive operation
that could also occupy a considerable amount of extra
disk-space.

Re-building a cache that is already tuned would waste
precious resources and would not communicate effectively
whether a config change is needed or not.

Show only the config changes needed and rebuild only
the caches that need adjusting, leaving everything else
unchanged.

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.
