Brandon Williams reassigned CASSANDRA-5182: ------------------------------------------- Assignee: Yuki Morishita > Deletable rows are sometimes not removed during compaction > ---------------------------------------------------------- > > Key: CASSANDRA-5182 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5182 > Project: Cassandra > Issue Type: Bug > Components: Core > Affects Versions: 1.1.5 > Reporter: Binh Van Nguyen > Assignee: Yuki Morishita > Attachments: test_ttl.tar.gz > > > Our use case is write heavy and read seldom. To optimize the space used, > we've set the bloom_filter_fp_ratio=1.0 That along with the fact that each > row is only written to one time and that there are more than 20 SSTables > keeps the rows from ever being compacted. Here is the code: > https://github.com/apache/cassandra/blob/cassandra-1.1/src/java/org/apache/cassandra/db/compaction/CompactionController.java#L162 > We hit this conner case and because of this C* keeps consuming more and more > space on disk while it should not. -- This message is automatically generated by JIRA.
