Hi guys, We have a 6-node 1.0.9 cluster for production and 3-node 1.1.0 cluster for testing the new version of Cassandra. In both we insert data in a particular CF with always a TTL of 31 days. To clean up the files faster we use the forceUserDefinedCompaction to manually force compaction on the old sstables which we are sure the data has expired. In 1.0 this works perfect, but in the 1.1 the command executes without error, but in the log of the node I see the following:
INFO [CompactionExecutor:546] 2012-07-02 15:05:11,837 CompactionManager.java (line 337) Will not compact MapData024CTwT/MapData024CTwT-HOS-hc-21150: it is not an active sstable INFO [CompactionExecutor:546] 2012-07-02 15:05:11,838 CompactionManager.java (line 350) No file to compact for user defined compaction I am pretty sure the sstable because it should contain partly expired data en partly data which is still active. Does this have to do something with the new directory structure from 1.1 ? Or are the parameters changed from the function? Kind regards, Pieter Callewaert
