Oleg: The simple answer for why I'm using Cassandra thusly is laziness/fear of uncertainty. I'm using Cassandra indirectly as the back end data store for Titan(http://thinkaurelius.github.io/titan/), which is a graph interface. Titan does let you swap out the data store, and it gives you several "canned" choices, one of which is Cassandra. BerkeleyDB might be a better choice for this project (and would address this issue), but it has licensing issues, so it's out, thus leaving me with using Cassandra or figuring out how to make Titan play with something like Derby. That's a project I just don't have time for or interest in. Apache HBase is another alternative, but that really seems like shooting a fly with an elephant gun...
Edward, I completely agree that it should be doable. Is this something that you would advise a simple user to tackle (i.e. does it make any sense at all for me to pull down the Cassandra codebase and try to figure out where the relevant code lives and what to change), or is it something the maintainers are likely to be willing to slip in as a simple feature? If the latter, do I just file a feature request somewhere? Thanks!

There are simpler noSQL stores than Cassandra that are better for embedding.

Moreover, we may want to start up multiple instances of the application, and right now whenever that happens, we get port conflicts on 7000 because Cassandra is listening for connections. I couldn't find an obvious way to disable listening on any port. Is there an easy way? Thanks! Mark -- Regards, Oleg Dulin http://www.olegdulin.com<http://www.olegdulin.com/>
