Evict cache entries when free space gets low Chronicle-map cannot expand indefinitely, but only to an upper limit which is based on the maxBloatFactor. When the number of possible expansions drops to zero and the percentage of free space in the last available segment falls under a configurable threshold (percentageFreeSpaceEvictionThreshold), cold cache entries are evicted from chronicle-map. Hot entries are kept in an LRU in-memory cache that holds a configurable fraction of the cache size. A cold cache entry is an entry that does not belong to this hot-cache and thus subject to eviction, in random order. Bug: Issue 13536 Change-Id: Iaf94a041943fb0680c2e3a222f3adda19915ae19
Non-blocking and super-fast on-disk cache libModule for Gerrit Code Review based on ChronicleMap on-disk implementation.
This libModule is built like a Gerrit in-tree plugin, using Bazelisk. See the build instructions for more details.
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.
