[jira] [Created] (HBASE-27229) BucketCache statistics should not count evictions by hfile

Bryan Beaudreault created HBASE-27229:
-----------------------------------------

             Summary: BucketCache statistics should not count evictions by hfile
                 Key: HBASE-27229
                 URL: https://issues.apache.org/jira/browse/HBASE-27229
             Project: HBase
          Issue Type: Improvement
            Reporter: Bryan Beaudreault


The eviction metrics are helpful for determining how much access-related churn there is in your block cache. The LruBlockCache properly ignores evictions by invalidation of HFile, but the BucketCache tracks them. 

We should make the BucketCache work similarly so that one can get an accurate view of the evictions occurring through too much random access or too large working set.
