Hi,
I'm trying without success to enable JNA for Cassandra on Windows.
Tried to place JNA 3.3.0 libs jna.jar and platform.jar into Cassandra 0.8.6
lib dir, but getting in log:
Unable to link C library. Native methods will be disabled.
What is missed or what is wrong?
One thing I've found on
There's possibility to use command line JMX client with standard Zabbix
agent to request JMX counters without incorporating zapcat into Cassandra or
another Java app.
I'm investigating this feature right now, will post results when finish.

What if it is OK for our case and we need counters with TTL?
For us Counters and TTL both are important. After column is expired it is
not important what value counter will have.
Scanning millions rows just to delete expired ones is not a solution.

We're using open source monitoring solution Zabbix from
http://www.zabbix.com/ using zapcat - not only for Cassandra but for the
whole system.
As MX4J tools plugin is supported by Cassandra, support of zapcat in
Cassandra by default is welcome - we have to use a wrapper to start zapcat
agent.

Hello,

Are records created in the Memtable from writes only or from reads
SCFs are very useful and I hope lives forever. We need them!

them. This is like you have 100% of data and each node will have 25% of the
data (random partitioning).

With 3 nodes and RF=2 you have 3 key ranges: N1+N2, N2+N3 and N3+N1.
Killing N1 you've got only 1 alive range N2+N3 and 2/3 of the range is down for
Quorum, which is actually all, so N1+N2 and N3+N1 fails.

This isn't a first time Cassandra has I/O issues on Windows.
I think it's not easy to review source code and eliminate such issues, but
would like developers to keep in mind such issues in the future.
We're also running a Cassandra cluster on Windows, but 0.7 beta1 (with similar
issue, but for

Always specify some constant value for timestamp. Only 1st insertion with that
But you'll loose these settings after Cassandra restart.

You can change these attrs using JMX interface.
We found that on Windows only log4j.properties is working for logging, not

Hi,
We're not setting cache capacity upon creation of Column Family, since the type
and capacity is unknown at that time. By default it = 0.
After Column Family has enough data and we could decide on cache type (Row or
Key) and capacity, we connect with JConsole and set cache capacity manually

needed to write a simple WindowsService class. In addition to the procrun
executables for 32/64 bit platforms and a batch file to install and remove the
service, I'll also be including an ant build file and associated unit tests.

We had similar experience.
Problem was with TSocket as transport alone:
var transport = new TSocket(192.168.0.123, 9160);
var protocol = new TBinaryProtocol(transport);
var client = new Cassandra.Client(protocol);
Using TBufferedTransport helped a lot:
var
TbufferedTransport instead.

I learned the hard way, that running py_stress in the src/contrib directory is
a great way to test what kind of speeds you are really getting.
What tools / client are you using to test to get the 200ms number?
