Subject [jira] [Created] (CASSANDRA-5182) Deletable rows are sometimes not removed during compaction
Date Wed, 23 Jan 2013 01:23:11 GMT
Binh Van Nguyen created CASSANDRA-5182:
------------------------------------------

             Summary: 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


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.
