There’s no way around the sandbox.
Scala is “enabled” via a JSR-223 provider - i.e. the same restrictions apply.
There’s no special handling for Scala.

cassandra-stress is a great tool to check whether the sizing of your cluster in
combination of your data model will fit your production needs. I.e. without the
application :) Removing the application removes any possible bugs from the load
test. Sure, it’s a necessary step to do it with your
to the correct
nodes. Although you can go into the C++ driver code and look how it works,
improve it etc. :)
I don’t know anything about the C++ driver - but feel free to post to the
driver mailing list and/or the #datastax-drivers IRC channel.

There is no way to mimic IF NOT EXISTS on UPDATE and it's not a bug. INSERT

Hi Kevin,
The difference here is that the Apache Cassandra site
and Achilles have both embedded C* (not in an OSGi container
though, and Carbon is with an older C* version).
We are wanting an “unzip and run” system and do not expect the user to have
to do much, if any, C* configuration.

You can also try http://caffinitas.org - Open Source Java object mapper for C*

close to what JPA does.
Although, it cannot support JPA features 1:1 since there are fundamental
differences between RDBMS and NoSQL/C*.
Let me respond with another question: How important is SQL for a JPA developer?
Mappers eliminate the boring and error-prone stuff like execute SELECT, read
fields, call setters etc. They can automatically perform conversions, apply
optimizations, etc etc etc.
Mappers do not remove the need of

There are unit test integrations using C* daemon. A related bug that prevented

It's perfectly fine to embed C* for unit tests.
