Subject Rebalance in apache Storm
Date Thu, 02 Feb 2017 05:27:46 GMT
Hello all,

I am research student and working on the dynamic scheduler for Storm.

*I just want to know the impact of Re-balance operation on messages loss.
i.e. What happens to the messages that are not processed within the wait
time for rebalance ?*

I found that on doing Re-balance operation only workers whose thread
mapping is changed is being re-started. So I have 2 choices now either To
reset mapping to all workers or design my logic in such way that minimal
old mapping is impacted. I was trying to figure out that is there any
benefit of doing one over the other.

Thanks & Regards,
Anshu Shukla
