Hi All,
We're taking advantage of the lull in traffic to go through a production
cluster upgrade from 1.2.x (latest) to 2.0.x (latest). We have three nodes
with a replication factor of three. I've noticed that the 'space used' has
almost doubled as a result of running 'nodetool upgradesstables'.

Nope, just ran out of disk space... So on 1.2.x I had 70GB used on a 200GB

Pelops is a very thin wrapper over the Thrift client so that could be a good
option.
You could also check out a fork by the VMWare/Spring guys which adds full async
support: https://github.com/andrewswan/scale7-pelops. I'm not sure on the
state of it, but it seems promising...

Hey all,
I can't seem upgrade to 0.7.5 using the Debian packages. Here's what I've

You can set up an instance of

org.scale7.cassandra.pelops.IConnection.Config.

Very nice!
You mention that the connections are handled internally by Pelops, does that
mean that potentially a different connection is used for each operation
performed?
I had assumed using the same connection for several operations with

So delete your data and commit log
The last time this came up on the list Jonathan Ellis said (something
along the lines of) if your application can't tolerate stale data then
you should read with a consistency level of QUORUM.
It would be nice if there was some sort of middle ground for an

Using the methods on the Bytes class would be preferable. The byte[]
related methods on UuidHelper should have been deprecated with the Bytes
class was introduced...
e.g. new Bytes(col.getName()).toUuid()

This is a known issue with the Cassandra 0.6 versions of Pelops. The issue
was fixed in the 0.7 based versions a few months ago but never back-ported
(Dominic, myself and the other contributors don't run 0.6)...

As you mention the map returned from multiget_slice is not order preserving,
