Hi,
I am no expert, but a couple of suggestions:1) Remember that writes
are very fast i Cassandra, so don't be afraid to store more
information than you would in an Sql-ish server. 2) It would be
better with an example, but again - by storing more than you would in
an sql-schema, would you still
Having (2) 1.2.5 nodes constantly crashing due to OutOfHeap errors.
It always happens when the same large compaction is about to finish (they
re-run the same compaction after restarting.)
An indicator is CMS GC time of 3-5s (and the many related problems felt
throughout the rest of the cluster)
I get these errors frequently as Cassandra starts up. I'm using the
official Java distribution from Ubuntu.

Hi all,
I am interested in using Cassandra in a Ruby on Rails project.
After a quick search on GitHub, there seems to be two clients that
stick out for use with Ruby:

* https://github.com/kreynolds/cassandra-cql
The documentation I've read suggested that u
Hi Renato,
Are you sure that you don't have two copies of guava in your classpath? I
don't have this problem (I was using both Hector and Astyanax for a while
-> now transitioned completely to Astyanax).
Probably the most problematic part of using the datastax or astyanax
clients is that they bot

One way to handle thee problems is to jar jar something. Essentially
repackage everything as something else and make the conflicts go away :)

This is true for different open source projects with different objectives.
But IMHO Cassandra clients aim to solve one main problem which is to
provide access to Cassandra, and as they all have the same goal, shouldn't
they be aligned for the Cassandra community? I mean if we want to change
from on
it's not unique to cassandra community. It's a problem across Java
community caused by Maven fanatics.
it's also the sad fact that too many popular open source projects have way
more external dependencies than necessary. As an apache committer I've seen
this across most java open source projects.
Thanks for your replies!
It is really a shame that is the way I would have to go. I am a contributor
for the Apache Gora[1] project and we were trying to support different
clients within our project but with those news, things really get
complicated :-/ maybe we will go with Intravert or DataStax c
Hi!
Just an update, the weekly repair seemed to solve it. The column is no
longer there.
Still strange...
