Tyler Hobbs commented on CASSANDRA-7930: ---------------------------------------- Okay, I reverted the patch for now. > Warn when evicting prepared statements from cache > ------------------------------------------------- > > Key: CASSANDRA-7930 > URL: https://issues.apache.org/jira/browse/CASSANDRA-7930 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Robbie Strickland > Assignee: Robbie Strickland > Labels: bootcamp, jmx > Attachments: cassandra-2.0-v2.txt, cassandra-2.0-v3.txt, > cassandra-2.0-v4.txt, cassandra-2.0-v5.txt, cassandra-2.0-v6.txt, > cassandra-2.0.txt, cassandra-2.1.txt > > > The prepared statement cache is an LRU, with a max size of maxMemory / 256. > There is currently no warning when statements are evicted, which could be > problematic if the user is unaware that this is happening. > At the very least, we should provide a JMX metric and possibly a log message > indicating this is happening. At some point it may also be worthwhile to > make this tunable for users with large numbers of statements. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
