I suspect there may be a connection between "the server was busy with
something and didn't die immediately with kill -INT" and "I was
getting timeout exceptions."

Interesting to note that cassandra wouldn't shut down properly and had to be
killed.

if you're timing out doing a slice on 10 columns w/ 10% cpu used,
something is broken
is it consistent as to which keys this happens on? try turning on
debug logging and seeing where the latency is coming from.

how many of the 3M columns are you trying to slice at once?
I'm evaluating Cassandra as a storage mechanism for monitoring data:
machine and process status reports, inventory, etc.
One of my concerns is bandwidth usage; I don't want Cassandra
replication traffic swamping more important traffic. I want to know if
there's a way to limit the bandwidth usage

I insert data like this
Calendar calendar = Calendar.getInstance();
calendar.setTime(dateAction);
calendar.set(Calendar.MILLISECOND, 0);
String millis = String.valueOf(calendar.getTimeInMillis());
ColumnPath columnPath = new ColumnPath(columnFamily,

if it gets a response between when it decides to time out and when it
logs the message, that could happen. or does it happen fre
There's no error on the source node other than the Timeout.
It appears to be occurring across multiple CF's (the majority of which are
normal columns).
I don't know an exact number but some of the CF's would have ~3million rows.
It seems odd that the error sometimes says received 1 response, but it

no.
for randompartitioner, you use integers from 0 to 2**127, but for OPP
you use strings from your key universe.

If I understand good if I transform my String key :: to

Is it correct ?? or there is something be
for OPP, tokens are equivalent to keys so pick keys evenly spaced apart

I've understand this but I don't know what to write into initialtoken is it

as I've said in a previous post My keys are build like ::

if you're not specifying initialtoken, every time you wipe your
installation it will generate new tokens. for a small number of
machines you'll definitely see some random tokens better balanced than
others.

Hi
I've build the 0.4.2 from the tags in SVN.
I've made exactly the same cluster with same configuration as 0.4.1
I've delete all the data in all server
Now I send the data to first server and the data is not more distributed
across the other server as previously.
I've configured replica to 1

For me the timeout occurs when I've a lot of request to the server. It was
working at 100% CPU and it seems that cassandra was receiving request and
keep them into the queue for more than 5000 millis then all the request was
rejected with timeout.
I can't think about another solution or to increas
