Subject Re: Does Storm work with Spring
Date Wed, 07 Oct 2015 03:29:39 GMT
Hi Ravi ,

I was able to make an Integration with Spring but the problem is that I
have to autowire for every bolt and spout . That means that even if i
parallelize spout and bolt it will get started to each instance  . Is there
some way that I only have to do for bolts and spouts once (I mean if I
parallelize bolts or spouts individually it can share the conf from
somewhere) . IS this possible??

Thanks
Ankur
