DCQUORUM is not finished in 0.6, which is why it's not documented
there. If you want to test it you'll need to live on the bleeding
edge of trunk (or wait for a 0.7 beta).

Hi
i'm using apache-cassandra-0.6.1. I am also trying to connnect to remotely and
always get java.net.ConnectException.
I have ensured Firewall is turned off in both windows machine.
I changed ThrifAddress to 192.168.2.55 as suggested in this thread but still get
same exception.

I see the Ruby cassandra gem now supports :count for get_range, which
means I can get the first of my slice of records when using OPP, but I
can't get the last without get_range supporting a :reversed => true
option. Does the underlying API support reversing a slice?
I just experienced a compaction that brought a node to 100% of its IO
capacity and made its responses incredibly slow.
It wasn't enough to make the node actually appear as down, though, so it
slowed down the operation of the cluster considerably.
The CF being compacted contains a lot of relativel
Well, it's been a few days on 0.6.2 and the new jvm and the behaviour looks

There's only one cache turned on, and it's a row cache, but the sizes of the
rows are identical and it's
Did you manually invoke a GC? It doesn't look like you're using
enough of the heap for it to care much on its own.

Cassandra supports slicing columns within a row in reversed order, but
not iterating rows in reverse.

You could try setting the compaction thread to a lower priority. You
could add a thread priority to NamedThreadPool, and pass that up from
CompactionExecutor constructor. According to
http://www.javamex.com/tutorials/threads/priority_what.shtml you have
to run as root and add a JVM option to get
Hi,
I have a list of posts I'm trying to insert into Cassandra. Each post has a
timestamp already (in the past) that is not necessarily unique. I'm trying to
insert these posts into Cassandra so that when I retrieve them, they are ordered
chronologically. When I insert them, I can't guarantee
Generate a timeuuid for each post based on the original timestamp.
