Jonathan Ellis commented on CASSANDRA-2786: ------------------------------------------- Nit: wouldn't it be cleaner to just pass gcBefore rather than the entire controller to EchoedRow constructor? +1 otherwise. > After a minor compaction, deleted key-slices are visible again > -------------------------------------------------------------- > > Key: CASSANDRA-2786 > URL: https://issues.apache.org/jira/browse/CASSANDRA-2786 > Project: Cassandra > Issue Type: Bug > Components: Core > Affects Versions: 0.8.0 > Environment: Reproduced on single Cassandra node (CentOS 5.5) > Reproduced on single Cassandra node (Windows Server 2008) > Reporter: rene kochen > Assignee: Sylvain Lebresne > Fix For: 0.8.1, 0.8.2 > > Attachments: 0001-Fix-wrong-purge-of-deleted-cf.patch, > 2786_part2.patch, CassandraIssue.zip, CassandraIssueJava.zip > > > After a minor compaction, deleted key-slices are visible again. > Steps to reproduce: > 1) Insert a row named "test". > 2) Insert 500000 rows. During this step, row "test" is included in a major > compaction: > file-1, file-2, file-3 and file-4 compacted to file-5 (includes "test"). > 3) Delete row named "test". > 4) Insert 500000 rows. During this step, row "test" is included in a minor > compaction: > file-6, file-7, file-8 and file-9 compacted to file-10 (should include > tombstoned "test"). > After step 4, row "test" is live again. > Test environment: > Single node with empty database. > Standard configured super-column-family (I see this behavior with several > gc_grace settings (big and small values): > create column family Customers with column_type = 'Super' and comparator = > 'BytesType; > In Cassandra 0.7.6 I observe the expected behavior, i.e. after step 4, the > row is still deleted. > I've included a .NET program to reproduce the problem. I will add a Java > version later on. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
