You're able to set the timestamp of the write in the client application.
If you have a table which is especially sensitive to out of order writes
and want to deal with the repeated second correctly, you could do slewing
at your client application layer and be explicit with the timestamp for
those s
Based on most of what I've said previously pretty much most ways of
avoiding your ordering issue of the leap second is going to be a "hack" and
there will be some amount of hope involved.
If the updates occur more than 300ms apart and you are confident your nodes
have clocks that are within 150ms
Thanks Ben for taking out time for the detailed reply !!
We dont need strict ordering for all operations but we are looking for
scenarios where 2 quick updates to same column of same row are possible. By
quick updates, I mean >300 ms. Configuring NTP properly (as mentioned in some
blogs in your
If you need guaranteed strict ordering in a distributed system, I would not
use Cassandra, Cassandra does not provide this out of the box. I would look
to a system that uses lamport or vector clocks. Based on your description
of how your systems runs at the moment (and how close your updates are
to
Following https://issues.apache.org/jira/browse/CASSANDRA-9131. It is very
interesting to track how the timestamp has moved from the user, to the
server, then back to the user quasi the driver.
Next we will be accounting for the earths slowing rotation as the ice caps
melt :)

Hi Ben,
Thanks for your reply. We dont use timestamps in primary key. We rely on server
side timestamps generated by coordinator. So, no functions at client side would
help.
Yes, drifts can create problems too. But even if you ensure that nodes are
perfectly synced with NTP, you will surely mes

pretty good overview
If you are using a timestamp as part of your primary key, this is the
situation where you could end up overwriting data. I would suggest using
timeuuid instead which will ensure that you get different prima
