If you are worried about the server side time drift (which usually should
not be a problem, right?) then you can also generate the timestamp on the
client side if that clock is more accurate. That probably should do it if
you can do that.
If you think that server clock drift will cause you problem
Thanks Hannu!
I wasn’t aware of the TokenAwarePolicy and that’s exactly what I was talking
about so I’ll give that a try. Because setting the consistency level doesn’t
really work unless I set it to ALL, but I really don’t want to pay that sort of
performance penalty. I’d rather stick with QU
Hi,
DataStax Cassandra Java Driver has the possibility to choose the
coordinator node based on the partition key (TokenAwarePolicy), however
that probably does not solve the consistency problem you are thinking about:
