Javier Canillas commented on CASSANDRA-1379: -------------------------------------------- Actually, on the patch both reads times will impact on the only read counter. Maybe creating a separate counter for cache reads and physical reads would be good. On the other hand, i dont remember if there is a miss counter over cache, if there is, it would be surely impacted > Uncached row reads may block cached reads > ----------------------------------------- > > Key: CASSANDRA-1379 > URL: https://issues.apache.org/jira/browse/CASSANDRA-1379 > Project: Cassandra > Issue Type: New Feature > Components: Core > Reporter: David King > Assignee: Javier Canillas > Priority: Minor > Fix For: 0.7.2 > > Attachments: CASSANDRA-1379.patch > > > The cap on the number of concurrent reads appears to cap the *total* number > of concurrent reads instead of just capping the reads that are bound for > disk.
