Thanks Loannis for the description. I think i got the idea of OSGi and i can see how making Helix OSGi ready can be useful in many applications, infact Helix itself might benefit by allowing pluggable rebalancers. I havent played with OSGi and dont think any one from the Helix dev team has played with this. So we really dont know what it takes to make Helix OSGi ready. Is this something you can drive, of course we can help you where ever needed.
I am also assuming that we will have a separate helix-OSGi module within Helix and thats the only module that might bring in additional dependency jars from OSGi. I prefer Helix-core to be light weight and not add additional dependency. Also making Helix OSGi ready does not mean thats the only way to deploy it. Let me know if any of my assumptions are wrong. This surely looks exciting, if you are up for making this happen please file a jira and I can ask more questions on the jira. Andrei, we should start a separate discussion thread on Helix and Provisionr. thanks, Kishore G On Fri, Mar 22, 2013 at 1:31 AM, Ioannis Canellos <[email protected]> wrote: > Hi Kishore, > > I am not sure about the implementation details of it.
