Hi,
I'm trying to figure out a reasonable amount of heap to grant to the
supervisor process on the storm worker machines. What are the factors that
must be considered? I'm thinking - size of the topology jar and number of
slots should be considered. But would like to hear if anyone was able to
Hi Neelesh,
We are having some issues with the running topology, I described it here -

We want to try using 0mq to check if replacing netty with it will make any
change.

Thank you for the link, Svend. But I'm afraid this doesn't work "out of

There is also no indication they are configuring Kafka such that it won't

The performance hit to Kafka is similar to Storm when you
This could happen if you have corrupted input that always causes a batch to
fail and be retried.
I have seen this behaviour before and I didn't see corrupted input. It
might be a bug in trident, I'm not sure. If you figure it out please update
this thread and/or submit a patch.

you only need to call ack once per input tuple, after all your emits are
done. so at the end.

It would of been far more useful if they measured the systems in terms of
dollars, as each system makes different tradeoffs. Certainly when you
enable acking you may become bottlenecked on CPU at that point instead of
being bottlenecked on disk/kafka. So one thing you can do is move to
hardware wit
zookeeper doesn't retain a version history.

no.
However there is a button at the bottom of the Topology UI "show/hide
system stats". Likely these are already hidden for you.

Hi Daria, I'm curious about why you decided to go back to zmq instead of
Netty. Did you hit any snags?

Daria,
Here are the old installation instructions of Storm (pre Netty), that
describe how to install a previous version, I think this was written with
0.8.2 in mind, together with its 0mq and jzmq dependencies, hopefully this
should help you get 0mz working with the latest version of Storm :

Hi All,
Is there way to hide the exposing of some parameters in the storm UI?
Thank you,
Vlad
