Are you sure you really need cassandra for this ? For me it sounds
like mysql or other databases would be a better fit for you (if you
don't need to store a very hugh amount of data...)

I created an issue and attached a patch:
https://issues.apache.org/jira/browse/CASSANDRA-2979
I was not sure if it would be better to handle it in NodeProbe or
StorageService..

I would also not use such a big heap. I think most people will tell
you that 12G -16G is max to use.

I would be very interested in this. I wrote a prototype for JAMES which
uses cassandra to store emails and provide them via IMAP and POP3 so it
would be nice to see your impl.

As far as I know its the library that was developed by "rackspace".
See
https://github.com/racker/node-cassandra-client
As rackspace is using node.js + cassandra I would expect it works ;)

Maybe you could make use of "Virtual Keyspaces".
See this wiki for the idea:

Hi there,
there is not such an operation in cassandra. The only thing which
comes "close" is the TTL support which will "delete" columns after a
given time. See:

No sure whats your problem..
Use two EQ operations works without a problem here (even via the cli).

To make it short... No.
You can only check if the Row contains at least one Column to
understand if its a Tombstone or not..

Hi there,
you would be better of to use a high-level client like hector or pelops.
See:
http://wiki.apache.org/cassandra/ClientOptions
But to answer your question... If you really want to use something lowlevel
then Thrift is the way to go...

To be more clear (maybe I was not before). BatchMutate is not atomic.
So it only "batch up" mutates to reduce overhead. So it can be that
you will receive data from it even if the whole operation is not
complete or will not complete.

No Zookeeper is not used in cassandra. You can use Zookeeper as some
kind of add-on to do locking etc.

Depending on finalize() is really not want you want todo, so I think
the API change would be preferable.
