IMHO, Cassandra write is more of a CPU bound task, so while determining cluster
write throughput, what CPU usage percent (avg among all cluster nodes) should
be determined as limit? Rephrase: what's the normal CPU usage in Cassandra
cluster (while no compaction, streaming or heavy-read running) ? For a cluster
with 10 nodes, i got 700K write per seconds for my data model, average cpu load
is about 40%, i'm going to increase number of native threads (now is 256) and
native queue (1024) to increase throughput (and CPU usage subsequently). Sent
