David King commented on CASSANDRA-1379: --------------------------------------- The ones on the active pages are, definitely. And they are the ones that need to not be blocked by slower-loading pages. > 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 > 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. That is, given N concurrent readers if all of them are busy waiting on > disk, even reads that can be served from the row cache will block waiting for > them. -- This message is automatically generated by JIRA.
