Matt Burgess commented on NIFI-6093:
------------------------------------
You're right, whether I think using the original is a good idea or not, the
other Split processors certainly do add those attributes, so there's likely a
good reason (probably your use case) and at the least SplitRecord should be
consistent with the other Split processors (hence NIFI-3988). I will add the
count and ID attributes to the original flow file, thanks for your explanation!

> Hello Team,
> As I already described in summary, SplitRecord processor missed fragment*
> attributes as result it is impossible to use Wait/Notify pattern to wait
> splits processing.
