Thanks Thibaut, believe it or not, it does. :)
Is your use case a typical web app or something like a scientific/data

I'm at a crossroads right now. We built an application around .7 and
the features in .7, so going back to .6 wasn't an option for us. Now,
we are in the middle of setting up dual mysql and cassandra support so
that we can "fallback" to mysql if Cassandra can't handle the workload
properly. It's
ed without adequate testing. Hopefully, at some point soon, it
will get better and doing a data import job won't take a cassandra
cluster to it's knees or we won't experience stop the world GC issues
and have out of memory errors from routine usage.

Hi Jake,
I'm sending this privately, because I wanted to tell you my opinion frankly.
I don't know about the .6 series or .74, but so far, all of the .7
series of cassandra has been a disaster. I would think twice about
switching to anything in .7 series to production until things stabilize
and
ld share, what happened in the default
config, what steps you did that helped the situation, h Tow much each
step helped your situation. That way we can start a checklist of things
to address as we grow in load.

Hi Ruslan,
It looks like Jonathan and Stu have already been working to reduce
garbage collection on v.8 The ticket is at
https://issues.apache.org/jira/browse/CASSANDRA-2252
Jonathan, is there any way to apply the patch to .73 and have ruslan

So, are you saying this is normal and expected from Cassandra? So,
under load, we can expect java garbage collection to stop the Cassandra
process on that server from time to time, essentially taking out the
node for short periods of time while it does garbage collection?
Also, why is there so mu
Hello,
I'm doing some testing of Cassandra and I've read a lot about people
running into situations growing their clusters. So, I'm about to test
it with .7.3. I've got a test node which is a single node with a
replication factor of 1. I'd like to grow it to 3 nodes and a
replication factor of
Hello all,
I was wondering if people could share their overall experiences with
using .7 series of Cassandra in production? Is anyone using it?
I see a lot of people have troubles on the list, but it's hard to see
which issues get resolved and which remain. So I was wondering how many
people ac

Hi all,
After using Cassandra some time, I had some comments on Cassandra and
hope they spark productive conversation on the list. They are meant
only as constructive feedback as a user of Cassandra. While there are
many things great about Cassandra, I still feel that the current
implementation
