It is simply not possible that you are inserting at CL.ALL (which is
what I assume you mean by CL for writes is 3) given how frequently you
are flushing memtables.  Flushing every 1.7 seconds with 300,000 ops
and your 60 columns per row indicates you are inserting 3000 rows/sec,
not 600.  The behavior shown in that logs is almost certainly from
inserting with CL.ZERO.  The code you provided does not include the
definition of "_writeConsistencyLevel".  Where is that set and what is
it set to?
