Hi Andras,
I am not using a VPN. The system has been running successfully in this
configuration for a couple of weeks until I noticed the repair is not
working.
What happens is that I configure the IP Tables of the machine on each
Cassandra node to forward packets that are sent to any of the IPs
Hi,
I have a question about cassandra 1.1
Just wanted to confirm if key_cache_size_in_mb is the maximum amount of
memory that key cache will use in memory? If not, what is it?
My observations:
With key cache disabled, I started cassandra. I invoked Full GC through
jconsole a couple of times just
Hi,
I am running into timeout issues using composite columns in cassandra 1.1.1 and
cql 3.
My keyspace and table is defined as the following:
create keyspace bn_logs
with strategy_options = [{replication_factor:1}]
and placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy';
Got it. Thanks Jake. Will do.

Hello,
How can I enable CQL3 support in Astyanax? Thanks very much for your help!

There are files that are recently created. One fat client node is storing
2.5GB of commit log files. The other 2 nodes are storing around 20MB of
files.
Question, would the commit log data be related to hinted handoff info in
the system CF? In other words, is hinted handoffs being store in the f
Hi
We have 8 cassandra 1.0.5 nodes with 16 cores and 32G ram, Heap size
is 12G, memtable_total_space_in_mb is one third = 4G, There are 12 Hot

memtable_flush_queue_size = 4 and memtable_flush_writers = 2..
I got this log-entry " MeteredFlusher.java (line 74) estimate

Hello Paul,
I thought but I can't reproduce the problem anymore... Don't know what
really happens.
Thanks very much for your message!

What do you mean when you say you can't display the related
documentations using the help command? What does cqlsh do instead? I
don't know about an
Hello,
What is the correct way to migrate a keyspace version 1.0.8 to 1.1.1? Is
there a documentation on this subject?
Thanks for your help.

Centos 6 apparently introduced a default nproc limit of
1024. I raised this for the cassandra user now and hope the crashes are
gone.
Thanks a lot for yo

Hi Sarfar,
Yes you should make it a multiple. The issue is each shard 'sticks' to a
given node but there is no way to guarantee 5 random keys will equally
distribute across 5 nodes. The idea is eventually they will as you add
more and more keys. So increasing shards at once can make that happe
Hi list
I have a small cassandra cluster consisting of three nodes. Every few
weeks the whole cluster goes down at the same time. All nodes show:

Ah, that sounds familiar. You don't mention if you are VPN'd or not. I'll
assume you are not.
So, your nodes are behind network address translation - is that to say they

Hello everyone,
I have a 2 DC (DC1:3 and DC2:6) Cassandra1.0.7 setup. I have about
300GB/node in the DC2.
The DCs are communicating over a gateway where I do NAT for ports 7000,
9160 and 7199.
I did a "nodetool repair" on a node in DC2 without any external load on
the system.
It took 5 hrs

That shouldn't happen.

Hi,
I was playing with Counters in Cassandra 1.0.10 and I see a behaviour
that I didn't expect. It's about removing a Counter column.
I'm used to use Mutation for everything, so the first thing I tried
was Deletion on Counter column. Well, nothing happened. No error and
