We decided to start with topology definitions in Clojure because a) that
ensures that the topologies can support 100% of Storm's Clojure DSL
out-of-the-box and b) that allows easy mixing of Python, Java, Clojure, and
even other multi-lang bolts. For example, we plan on producing example
topologies

Totally agree. I'd switch back to Python in a second if I could. Might be
worth taking a look at the pluggable serializer.

I am in the process of optimizing my stream. Currently I expect 5 000 000
tuples to come out of my spout per minute. I am trying to beef up my
topology in order to process this in real time without falling behind.
For some reason my batch size is capping out at 83 thousand tuples. I can't

Michael R,
We don't have GC logging enabled yet. I lean towards agreeing with Derek that I
don't think it's the issue but I will take a look at logging on Monday just to
verify.
Derek D,
Are you certain that nimbus.task.timeout.secs is the correct config? Tracing
through the github code it
Hi,
We are using storm 0.9.0.1, and one topology got { "topology.workers",
nil} in the config and it crashed nimbus with this stack trace. Then each
time we try to restart nimbus it also crashes with the same stack trace. Is
the zookeeper in a bad state If so how do we clear it?

For one thing, a recently accepted Storm pull request has made this
serialization pluggable and someone has already implemented a protobuf
variety. We plan to investigate alternative serialization options for
multilang once we get the other tooling out of the way.
For another, it is true the overh
We had experimented with Storm/Python 6 months ago or so, but found the
JSON serialization/deserialization overhead was quite high, on the order of
several hundred usec per tuple every time it transitioned from java to
python or vice versa, limiting total throughput on a 12 core server to
around 25
Not sure about the eclipse but I would recommend to import as maven
project from eclipse.

Can you please tell me about the initial error that i got?
What i did was i created a separate Maven project in Eclipse. I copied
corresponding files
>From the logs it seems to me the issue is with zookeeper not releasing
lock on log files and storm trying to cleanup the logs. Its a known
issue for zookeeper in windows. If you can try upgrading to 0.9.1 but I
don't think that will fix it though.

Hi,
Thanks for the input. I did run the command as suggested. I get below
exception. I am running command as administrator using Windows 7.
A separate question - Does Storm 0.7.1 which is written in original POm
file in downloads, support Windows?
Exception that i got was :-
