As a side note, if you're inserting records quickly enough that you're
potentially doing multiple in the same millisecond, it seems likely to me
that your partition size is going to be too large at a day level unless
your writes are super bursty: ((appkey, pub_date), pub_timestamp). You
might need
Thanks Ben, Paul, Alain. I debug at client side find the reason is
pub_timestamp duplicated. I will use timeuuid instead.

Hi Linbo,
+1 with what Ben said, timestamp has a millisecond precision and is a
If pub_timestamp could possibly match I'd suggest making it a timeuuid type
instead. With the above schema it's not a failure or data loss if the
timestamp is duplicated - your writes all probably made it - the
duplicates just got overwritten.

Is it possible that your pub_timestamp values are colliding (which would
result in an update rather than an insert)?

Hi,
I use Erlang driver to send data to Cassandra, do testing at local
environment meet data lost issue. I have no idea what step is wrong.
