Yu Li created HBASE-15162: ----------------------------- Summary: Add separate metrics for meta/data block hit ratio in cache Key: HBASE-15162 URL: https://issues.apache.org/jira/browse/HBASE-15162 Project: HBase Issue Type: Improvement Reporter: Yu Li Assignee: Yu Li
Currently we already have a metrics in name of {{blockCacheExpressHitPercent}} to indicate the cache hit ratio. However, since meta block is small and often cached in memory with a high hit ratio, this "mixed" metrics could not show the real data block hit ratio which is more concerned. We propose to add two new metrics to show meta and data block cache hit ratio separately, while reserving the old metrics for backward compatibility. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
