I am using Cassandra 1.1 (sorry bit old) and I am seeing high pending
compaction count. "pending tasks: 67" while active compaction tasks are not
more than 5. I have a 24CPU machine. Shouldn't I be seeing more compactions? Is
this a pattern of high writes and compactions backing up? How can I improve
this? Here are my thoughts.
Increase memtable_total_space_in_mbIncrease
compaction_throughput_mb_per_secIncrease concurrent_compactions
Sorry if this was discussed already. Any pointers is much appreciated.
Thanks,Kumar
