Summary: Discard pooled readers for cold data Key: CASSANDRA-5661 URL: https://issues.apache.org/jira/browse/CASSANDRA-5661 Project: Cassandra Issue Type: Bug Components: Core Affects Versions: 1.2.1 Reporter: Jonathan Ellis Assignee: Pavel Yaskevich Fix For: 1.2.6 Reader pooling was introduced in CASSANDRA-4942 but pooled RandomAccessReaders are never cleaned up until the SSTableReader is closed. So memory use is "the worst case simultaneous RAR we had open for this file, forever." We should introduce a global limit on how much memory to use for RAR, and evict old ones. -- This message is automatically generated by JIRA.
