I have a column family where I'm doing 500 inserts/sec for 12 hours or so at time. At some point my performance falls off a cliff due to time spent doing compactions.
I'm seeing row after row of logs saying that after 1 or 2 hours of compactiing it reduced to 100% of 99% of the original. I'm trying to understand what direction this data points me to in term of configuration change. a) increase my compaction_throughput_mb_per_sec because I'm falling behind (am I falling behind?) b) enable multi-threaded compaction? Any help is appreciated. Brian
