Ryan Svihla updated CASSANDRA-15626:
------------------------------------
Description:
In CASSANDRA-15557 the fix for the flaky test is reimplementing the logic from
CASSANDRA-12997 which was removed as part of CASSANDRA-13426
However, since dropped columns are stored at a millisecond precision instead of
a microsecond precision and ClientState.getTimestamp adds microseconds on each
call we will lose the precision on save and some writes that should be dropped
could reappear.
Note views affected as well
