Hi everybody,
We set row cache too high, 1 or so and now all our 6 nodes fail

Yes - you would need at least 3 replicas per data center to use

Hi All,
Cassandra documentation here:
http://www.datastax.com/docs/0.8/data_model/supercolumns
states that:
Any request for a sub-column deserializes all sub-columns for that super
column, so you should avoid data models that rely on on large numbers of
sub-columns.
Is this still true?
Thank
Hi,
First of all, thank you for releasing v8.0.1 and congrats! the list of fixes
and improvements is impressive.
Is there any ETA for Debian package? Is there a (standard) way to build it
from sources?
Thank you,
Oleg

Indeed I did not configure NetworkTopologyStrategy. Are you saying

I wonder what it the right way to configure replication in Cassandra cluster.
I need to have 3 copies of my data in a cluster consisting of 6 nodes.
3 of these nodes are in one datacenter - let's call it DC1 - and 3 in
another, DC2. There is a significant latency between these datacenters

I'm trying to implement a simple CRUD service based on Cassandra. I use

While writing tests, I found out that if I create a few columns using API,
