Hi guys,
I have a small setup with 3 macs running os x snow leopard and the

I am doing a lot of inserts, without any problems and I can read the
data again.
But
At some point, around 1G Commitlog size, cassandra starts a rise in
ram usage, unt

What version are you running? Take 0.4 from trunk.
Default config has
128
Did you change it allow your commit log chunks be 1Gb?

O.k... I experimented a bit: changed "-Xmx1G \" to "-Xmx2G \" in bin/
cassandra.in.sh ...
Is it really nescessary to have as much RAM as you have data?!?!?
Best regards

Sorry about that... running 0.4 taken from trunk.
I didn't change CommitLogRotationThresholdInMB - it's still 128
Thanks!

I had similar OutOfMemory issues, see "commit logs are not deleted" thread,
but it was fixed/commited to trunk.
What I don't get is how your commit log segment grows beyond threshold.

No, I was able to insert 50Gb worth of data wi
I don't know why... But for some reason, the commitlogs grew bigger
than 128MB - so I suppose a manual compact was needed...?!?!
Anyways... I restarted with the 2GB value in cassandra.in.sh,
everything got compacted, the commitlog rotated - and I could stop,
change the settings back and start

I will check that thread out! Thanks :-)
Maybe I should try to refresh the code...
I am starting to think, it might be the "native" java of snow leopard,
that is causing some of my problems...
This is what has kept me from coding Java for more than a decade...
Java is never just Java...

One tip: don't use ConcurrencyLevel.ZERO when bulk inserting. It's
easy to OOM yourself that way.

Thanks for the tip!
I'm using QUORUM - I hate losing data :-P

Hi All,
I'm going to go ahead and be "that guy", here. I haven't been involved
in this process at all yet. So, it's probably too late to voice this
opinion. But, I'm going to go for it anyway.
I'm not a huge fan of any of the selections on the ballot. The eye

Hi,
I was wondering if it's a good idea to use Cassandra for persist-able
circular buffer?
http://en.wikipedia.org/wiki/Circular_buffer
The goal is to have at most X columns per key, where new columns wipe old
columns out.
There will be much more writes than reads. What bothers me is how to handl
It's not a fantastic fit because as you say you need to read the
contents to be able to see which if any need to be deleted. (On the
bright side if you are sorting by time uuid, for instance, you won't
need an extra sort step.)
I would predict it would perform better than doing the same thing in
Are there any hooks (API), for instance I could implement a simmilar
RowMutationVerbHandler: IVerbHandler that would do the purging on the server
side?

My bad...I guess that makes it even more important to find out if this
is the problem on Windows? :)

We're looking at the website and can't find any definitive working
example of where to get the Cassandra libraries for java from Maven. Is
this available?

Exact explanation to why Java NIO behave that way on Windows 2003 in Sun VM
1.6.0.16 represent only academical interest.
It would be nice though, if someone could repeat my tests and would confirm
or deny the result.

Please correct me if I'm wrong... but i didn't see the cassandra libraries
in maven repositories.
You can download the source distribution of cassandra, and look at the
pom.xml included.
The pom.xml will show you all the dependencies required, and it'll be easy
enough to deploy to your local mave

No, it's not, sorry. I'm not sure this is even practical since we have
