@revans2 thanks for merging. Raised
https://github.com/apache/storm/pull/2835 for 1.x-branch.
>If you want to send more it can be more efficient, but you risk going over
the max.spout.pending amount that is set by the user, and in 2.x where an emit
can block, you risk having the spout block as well.
If the emit can block in 2.x it might be an issue to address because its
not in spout contract to necessarily emit only one record. I thought it could
overflow and the max.spout.pending is not that relevant with the back pressure
changes.
