Fwd: Reliability in storm 0.9.4

2018-03-12 Thread Shubham Gupta
Hi, I had a few doubts regarding storm reliability mechanism : - Do we need to ack (or fail) unanchored tuples ? - Is is always necessary to ack or fail every tuple received from the spout in the first bolt to avoid Out of Memory error in Storm ? Thanks in advance Regards Shubham Gupta

I'm basing this off of later Storm versions, because I'm not familiar with 0.9, so buyer beware. As far as I know the logic hasn't changed though, so I'll be linking to the 2.0.0 classes. 1. No, you don't need to ack or fail unanchored tuples. Storm isn't keeping track of those tuples at all.

In my personal experience, I could say like try to upgrade for latest version. Because I could see stability issues like disruptor queue fills up and storm getting hung in 0.9.4 version. I am in the upgrade process now migrating from 0.9.4 to 1.2.1 On Tue, Mar 13, 2018, 2:05 AM Shubham Gupta
