Hi Everybody, JConsole tells me I've got CompactionReducer threads stacking up, consuming memory, and never going away. Eventually, my Java process fails because it can't allocate any more native threads. Here's my setup…
Cassandra 1.0.5 on CentOS 6.0 4 GB of RAM 50 GB SSD HD Memtable flush threshold = 128 MB compaction throughput limit = 16 MB/sec Multithreaded compaction = true It may very well be that I'm doing something strange here, but it seems like those compaction threads should go away eventually. I'm hoping the combination of a low Memtable flush threshold, low compaction T/P limit, and heavy write load doesn't mean those threads are hanging around because they're actually not done doing their compaction tasks.
