you can use tools like chef along side vagrant to bring a cassandra. I
personally prefer LXC containers, as they mimic full blown vms, along side
chef-lxc which provides chef's awesome DSL for container customization
(similar dockerfile, and you wont install chef inside the container), for
our scen
Hi Kevin
We are using a similar solution than horschi. In the past we use CassandraUnit
(https://github.com/jsevellec/cassandra-unit) but truncate the tables after and
before each test works better for us. We also set gc_grace_seconds to zero.

Thanks Alex for inputs. As you said, choosing right consistency levels
will be critical here.

FWIW we run a 3 node cluster with ccm on Travis to regression test the
gocql driver - here's the descriptor:

Hi Kevin,
I run my tests against my locally running Cassandra instance. I am not
using any framework, but simply truncate all my tables after/before each
test. With which I am quite happy.
You have to enable the unsafeSystem property, disable durable writes on the
CFs and disable auto-snapshot in
Kevin,
Have you looked at the Cassandra integration tests used by the Cassandra
development team: https://github.com/riptano/cassandra-dtest ? They make
use of CCM for integration testing: https://github.com/pcmanus/ccm

Curious to see if any of you have an elegant solution here.
Right now I”m using cassandra unit;
https://github.com/jsevellec/cassandra-unit
for my integration tests.
The biggest problem is that it doesn’t support shutdown. so I can’t stop
or cleanup after cassandra between tests.
I have other
I thought setcompactionthroughput just adjusted the compaction speed when the
server is online? I'm looking for something like a scrub (which as far as I
know does not do this) that will compat the tables appropriately while the
Cassandra daemon is down.
And I know why I've got heap pressure--

I feel like similar questions have been asked recently but not in this specific
way:
I have a cluster that has some I/O capacity issues, which I know is what's
really causing this, but I've got the case where (using leveled compaction
strategy) my SSTables are piling up at the lowest level. I
Just make sure you understand the effect of consistency levels on your
performance. You (probably) don't want to be going over the WAN for reads
etc.
We run across the US/EU AWS regions and don't have any problems with higher
RTT.
