I wonder if one particular node is having trouble; when you notice the
missing column, what happens if you execute the read manually from cqlsh or
cassandra-cli independently directly on each node?

Hey,
I found out that the problem is caused by this line :

That repo for libcassandra works for cassandra 0.7.x due to changes in the

May be you can take a look to my fork of libcassandra https://github.com/axs

We loaded 5 million columns into a single row and when accessing the first 30k

rows from the beginning and end and saw no performance difference. I am sure
reverse sort is there for a reason though. In what context

hi Alexis,
Even if I create keyspaces, column families using cassandra-cli, the column
creation and insertion work will still need thrift calls.

Shubham,
You are right, my point is that with non schema-update thrift calls you can
tune the consistency level used.

Hi all,
I have a Cassandra Cluster running and we recently duplicated the cluster.
After following all the steps, the cassandra clients started failing with the
following message:

We are using Cassandra 1.2 Embedded in a production environment.
We are some issues with these lines:

In one of our load tests, we're incrementing a single counter column as
well as appending columns to a single row (essentially a timeline). You can
think of it as counting the instances of an event and then keeping a
timeline of those events. The ratio is of increments to "appends" is 1:1.

For what its worth. I did this when I had this problem. It didn't work
out for me. Perhaps I did something wrong.

Don't. Managing tokens with ByteOrderedPartitioner is very hard anyway,

We were able to implement ByteOrderedPartition on Cassandra 1.1 and insert
an object in a specific machine.
However, with Cassandra 1.2 and VNodes we can't implement VNode with

Can someone remind me why replicate on write tasks might be related to the
high disk I/O? My understanding is the replicate on write involves sending
the update to other nodes, so it shouldn't involve any disk activity --
disk activity would be during the mutation/write phase.
The write path (not

I'm afraid you got it wrong. The read done during counter writes *is* done
by the replicate on write taks. Though really, the replicate on write taks
