Nick Dimiduk created PHOENIX-2939: ------------------------------------- Summary: MetaCache is easily thrashed with default settings Key: PHOENIX-2939 URL: https://issues.apache.org/jira/browse/PHOENIX-2939 Project: Phoenix Issue Type: Bug Reporter: Nick Dimiduk
With default settings for {{phoenix.coprocessor.maxMetaDataCacheSize}} (20mb) and {{phoenix.stats.guidepost.width}} (100mb * 3), even a relatively small amount of data (ie 10TB, 2000 regions) will easily produce more stats data than fits in the cache. This quickly leads us into a situation where we thrash the cache and spend an inordinate amount of time (re)scanning SYSTEM.STATS table. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
