For backwards compatibility purposes, I think changing the default 100
Maximum Number of Bins to 5 will have a large impact on users. Right now most
people just leave this at the default. If they upgrade NiFi and they were
regularly using 10 bins, for instance, then after the upgrade their
MergeContent will behave a LOT differently.
What memory footprint are we targetting for this change? Even with a 512
MB heap, 100 bins does not cause problems.
I have really big concerns about this one. Can we discuss more?
