Joe Skora commented on NIFI-641:
--------------------------------

In the interest of eliminating the hard-coded batch size, {{session.get(100)}}, 
in this processor, I see a couple alternatives.
# Add a batch size parameter so the user can control batching.
# Remove the batch size parameter in the {{session.get()}} call and add the 
{{@SupportsBatching}} annotation so the framework can control batching.

*I think #2 makes the most sense considering ^\[1]^ but I'd like to hear any 
thoughts on that before changing it.*

Thanks,
Joe
----
^\[1]^ Scanning the source tree shows 533 calls to session.get().
* 433 have no parameter (batchsize=1)
* 75 have a hard-coded batch size
* 25 have a configurable batch size

> create a processor for the deletion of attriubutes.  There is currently no 
> way to remove attriubtes from a flowfile, the best a DFM can is blank out an 
> attribute, but that still allows the attriubute to be passed on
