Hey @JohannesDaniel - just made new tests and can't reproduce what I saw
previously... so let's forget about it :) (thanks for the unit tests though!)
I tested the EL support for tag validation, working well, thanks for the
addition. I'd just make one suggestion: right now for the record tag, "in the
case of a mismatch, the respective record will be skipped". I'd suggest to make
this behavior configurable through a parameter in the CS: skip the record
(current behavior) or throw an exception for the flow file (as you're doing for
the root tag validation).
Regarding the performance test, it was a GFF => ConvertRecord (XML to JSON)
=> UpdateAttribute. Don't remember the exact numbers but IIRC it was around
1300 flowfile per second with an XML payload of 6KB (single record in my case).
Overall, it's really cool!
I'll try to have a look over the code during the week.
