Chandresh Pancholi commented on IGNITE-429:
-------------------------------------------

There is no point running another ignite instance after topology because we are 
closing ignite instance in streamer everytime.
In beforeTest() method i am starting ignite node but getting error saying 
org.apache.ignite.IgniteCheckedException: Default grid instance has already 
been started.

> We have {{IgniteDataStreamer}} which is used to load data into Ignite under 
> high load. It was previously named {{IgniteDataLoader}}, see ticket 
> IGNITE-394.
> See [Apache Storm|https://storm.apache.org/] for more information.
> We should create {{IgniteStormStreamer}} which will consume tuples from Storm 
> and stream them into Ignite caches. 
> More details to follow, but to the least we should be able to:
> - Convert/Intercept Storm tuples to Ignite data using an optional pluggable 
> converter.
> - Specify the cache name for the Ignite cache to load data into.
> - Specify other flags available on {{IgniteDataStreamer}} class.
