Hi,
If you're already using cassandra for storing your data, you might be
interested in http://pithos.io which provides s3 compatibility. The
underlying schema splits files in several blocks, themselves being split in
chunks.
I'm looking forward to all your comments on the schema, code and of
Have you tried the Datastax java driver?

I am seeing that version 1.1-4(which I believe is latest release?) has been
there around since very long
If you're using C* v2 I suggest you to switch to the latest DataStax
JavaDriver which the only one who supports C* v2. Also you can use
Astyanax in order to switch to its API but having something like DS
JavaDriver under the hood.
It may be interesting for you
It looks like MagnetoDB for CloudStack.
Nice Clojure project.

Umm.. That means there *are *some issues with Hector ! Btw both Hector
Datastax java driver are maintained by Datastax, both for java, this
speaks for itself !
My project is going to production very soon.. I would need to switch to
new library. Are there any major differences between Hector

I'm not sure about the first statement. What do you mean at the second
part of the sentence?

Hi all,
thanks for the help. the issue happened again. I looked into Romain's
suggestion and yes, it was VMware balloning.
So, i will not be updating the jira ticket as I am not sure if the fix
actually helped or not.
Thanks,
Prem

Hello,
Compaction strategy, leveled vs. sized tier, will impact the amount of
compaction that occurs, i.e. compaction time, more than the two data model
options. Check out this blog for more information on the types of
compaction strategy -
Hi Romain,
There is a stronger parallel with switft in the openstack world. But the
more evident parallel is with riak-cs for riak.

We're running an insert-heavy use-case and have set durable_writes =
false for all of our keyspaces. While inserts are coming in (about
2000 1k-records per second), we are still seeing 50Mb written to files
in the commitlog directory every 6-10 seconds (using iostat).
Anybody know why so
Are you writing these records as batches (with begin batch, not begin
unlogged)? As a logged batch ('begin batch' is logged) gets written to a
system keyspace with CL before being applied to the underlying CF, and I'm
not sure we want to go special casing that for non-durable writes, since
you
If the number of types and dates per customer are reasonable modest (dozens?
hundreds?) it may not matter much at all. What are the numbers here,
average/maximum types per customer and dates per customer? In fact, depending
on the numbers, maybe the partition key should only be the customer. I

On http://rpm.riptano.com/community/noarch/ what's the difference between
cassandra20-2.0.6-1.noarch.rpmhttp://rpm.riptano.com/community/noarch/cassandra20-2.0.6-1.noarch.rpm
and

I'm using Oracle Java 7 on a CentOS 6.5 system.
Running 'java -version' works correctly and shows
I'm running Oracle Java. I don't want to use OpenJDK.
This is good since I notice that the Datastax
documentation in several places says to install
Oracle Java, not OpenJDK.
I want to install
I have noticed that too. But even though dse installs opsndjk, it never
gets used. So you should be ok.

But with two version of Java installed you then have to
make extra sure that Oracle Java is being used.
It just seems like a good idea to follow
Java on linux has *always* been a hassle. Recently, installing ant via
apt-get on an active ubuntu still want to yank in components of GCJ

I've done a little more research on this problem.
I'm now convinced that this is a Cassandra problem,
but not the problem I had originally thought.
For example, I downloaded cassandra12-1.2.15-1.noarch.rpm
and I then ran the following with the results shown:
