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

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
