If you switch your writes to CL ONE when a failure occurs, you might as well

That's finally a precise statement! :) I was wondering what to at least 1

Recent versions of Cassandra (I noticed it in RC1, which is what I am using)
add a very cool estimateKeys JMX operation for each column family. I have
a quick question: Is the value an estimate for the number of keys on a
particular node or for the entire cluster?
I have a 5 node cluster
Thanks for your help Peter.
We gave up and rolled back to our mysql implementation (we did all writes to
our old store in parallel so we did not lose anything).
Problem was that every solution we came up with would require at least on major
compaction before the new nodes could join and our
Is there any database viewer in cassandra to browser the content of the
database, like what DB2 or oracle have?

has anyone tested hazelcast as a distributed locking mechanism for java
clients? seems very attractive on the surface.
Over the past month or so, it looks like memory has slowly
been exhausted. Both nodetool drain and jmap can't run, and
produce this error:
Error occurred during initialization of VM
Could not reserve enough space for object heap
We've got Xmx/Xms set to 4GB.

Hi, I'm using it as a complement of cassandra, to avoid duplicate
searches and duplicate content in a given moment in time.
It works really nice by now, no critical issues, at least the
functionallity I'm using from it.

I don't know much about Zookeeper, but as far as I read, it is out of
JVM process.
Hazelcast is just a framework and you can programmatically start and
shutdown the cluster, it's just an xml to configure it.
Hazelcast also provides good caching features to integrate with
Hibernate, distributed
So you're actually getting n+1 record? Correct? So this is the right way to
do it?

Or you can just start at the 1 + nth id given ids must be unique (you don't
have to specify an existing id as the start of a slice). You don't HAVE to
load the n + 1 record.
This (slightly) more optimal approach has the disadvantage that you don't
know with certainty when you have reached the

Perhaps other, more experienced and reputable contributors to this list can
comment but to be frank: Cassandra is probably not for you (at least for now).
I personally feel Cassandra is one of the stronger NoSQL options out there and
has the potential to become the defacto standard; but its not
