Hi there,
I’d like to share a very simple project around handling CQL files with
maven. We were using the cassandra-maven-plugin before, but with
limitations on the authentication and the use of thrift protocol. I was
tempted to write a replacement focused only the execution of CQL
statements, in
Primary-key select is pretty fast in rdbms too and they also have caches.
By "close to" you mean in latency ?
Have you thought why people don't use cassandra as a cache ? While it
doesn't have LRU, it has TTL,replicatio,sharding.

Is there a way to call this programatically such as from unit tests, to
create keyspace / table schema from a cql file?

At this moment no, as this is a maven plugin. Extracting such code would be
relatively trivial.

around using CCM for integration testing:

You define clusters and nodes in configuration, then ask the service to go:

I’m asking this here. I’m asking the community for their POV when it might
make sense to front Cassandra with Hazelcast. This is even mentioned as a use

Cassandra is a database, not an in-memory cache. Please don't abuse
Cassandra like that when there's plenty of existing distributed cache
products designed for that purpose.
That's like asking "why can't I drag race with a school bus?"

@Peter: Thanks for that comment! Thats pretty much what I thought when
reading the phrase why not to use CS as a cache.

If your real world case requires more performance, one option is always to

Hello cassandra-users,
I'm investigating an issue with JVMs taking a while to reach a safepoint. I'd
like the list's input on confirming my hypothesis and finding mitigations.
My hypothesis is that slow block devices are causing Cassandra's JVM to pause
completely while attempting to reach a saf

Actually it's recommended to run C* without virtual memory enabled. So if there
is no enough memory JVM fails instead of blocking
