Hi All,

I ran nodetool cfstats (v2.0.14) on a keyspace and found that there are a few large partitions. I assume that since "Compacted partition maximum bytes": 802187438 (~800 MB) and since
"Compacted partition mean bytes": 100465 (~100 KB), it means that most partitions are in okay size and only a few are large. Am I assuming correctly?

If so, can anyone suggest how to find those large partitions and how to deal with them? (cfstats output below)

Thanks!
