Hi Shaikh,

I heard some throughput bottleneck of storm. It cannot really scale up with
kafka.
I recommend you to try DataTorrent platform(https://www.datatorrent.com/)

The platform itself is not open-source but it has a open-source library (
https://github.com/DataTorrent/Malhar) which contains a kafka ingestion
functions.
The library is pretty cool, it can scale up dynamically with kafka
partitions and is fully HA.

And in your case you might be able to use the platform for free.(It's free
if your application doesn't require large amount of memory)

With datatorrent platform and the open-source library I can scale my
application up to 300k/s (10 nodes, 3 replica, 1kb msg, 0.8.0 client).
I heard the performance of kafka client has been improved for 0.8.1 release
:)

Best,
Siyuan
