Description
When the database is empty, the idle time cpu usage of Cassandra is around 2%. But after I created 1500 tables, the cpu usage increases to 10%.
I checked with top -H and jstack and found two metric-meter-tick threads both consumes around 5% cpu.
If I remove all 1500 tables, the cpu usage decreases.
Is this a problem or is an inherent design property of Cassandra?
