> We are seeing High CPU Load about 80% to 100% in Cassandra 2.1.8 when doing Data ingest,
we did not had this issue in 2.0.x version of Cassandra
> we tested this in different Cloud platforms and results are same.
> CPU: Tested with M3 2xlarge AWS instances
> Ingest rate: Injecting 1 million Inserts each insert is of 1000bytes
> no other Operations are happening except inserts in Cassandra
> let me know if more info is needed.
