Hi everybody,
We set row cache too high, 1 or so and now all our 6 nodes fail
with OOM. I believe that high row cache causes OOMs.
Now, we trying to change row cache sizes using cassandra-cli update
column family command but Cassandra nodes keep dying.
Any help is appreciated, it's a product

I believe I don't quite understand semantics of this exception:

Does it mean there *might be* enough?

Hi all,
I have a question that documentation has not clear answer for. I have
the following requirements:
1. Synchronously store data in datacenter DC1 on 2+ nodes
2. Asynchronously replicate the same data to DC2 and store it on 2+
nodes to act as a hot standby
Now, I have configured keyspaces w
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?

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

Guys,
I'm a bit puzzled today. I'm using just released Hector 0.7.0-29
(thank you, Nate!) and Cassandra 0.7.4 and getting the exception
below, marked as (1) Exception. When I dig to Cassandra source code
below, marked as (2) Cassandra s
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
and orig

Hi,
http://cassandra.apache.org/download/ shows that
"The latest stable release of Apache Cassandra is 0.7.0 (released on
2011-01-09). If you're just starting out, download this one."
However, I don't see this version in Riptano public repository. The latest
there is still 0.7.0-rc4.

Hi there,
I'm trying to implement a simple CRUD service based on Cassandra. I use
Hector client.
While writing tests, I found out that if I create a few columns using API,
then delete them from cassandra-cli and and re-create them using the same
code (same key, etc), I can never get these new co
