-------------------------------------------
Summary: SSTablesPerReadHistogram seems wrong when row cache hit
happend
Key: CASSANDRA-10585
URL: https://issues.apache.org/jira/browse/CASSANDRA-10585
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Ivan Burmistrov
Priority: Minor
Fix For: 2.1.x
SSTablePerReadHistogram metric now not considers case when row has been read
from row cache.
And so, this metric will have big values even almost all requests processed by
row cache (and without touching SSTables, of course).
So, it seems that correct behavior is to consider that if we read row from row
cache then we read zero SSTables by this request.
