Hey! I have a question about the storm topology lifecycle. Are there any hooks in the storm deployment/topology lifecycle? Basically I'd be great if there was a way to run a block of code during deployment of a new topology that got fired once on each JVM.
The issue we've seen so far is when deploying a topology, sometimes we need to setup some kind of shared resource, maybe a connection pool of some type (JDBC, HTTP, etc..) and its currently not trivial to do that via the bolt prepare methods such that it only happens once per JVM. Its possible, but easy to get wrong :p Does something already exist within the storm framework for this that we've missed? Is it a case of "you're doing it wrong"? Thanks! Stephen
