MiNiFi CPP Processor naming -- Sets attribute to value of content
NiFi/MiNiFi Developers,
I am currently working on a very simple processor which sets the value of a configurable attribute to be the value of the content of the flow (interpreted as a UTF-8 string).
The most natural name I can think of is ContentToAttribute, but I'm not sure that conforms to the naming standard. There is a "To" processor in NiFi (AttributesToJSON), but most start with a verb. What would you call this new processor?
Regards,
Andy

Unfortunately, it looks like this one is blocked by dynamic properties [1]. In the meantime, we will put together a skeleton which simply matches ".*" and puts it into an attr specified by a property which we'll remove when dynamic properties are supported. As such, that ExtractText will sit on a branch on github until dynamic properties are done and this can be fleshed out properly.

Pierre,
Agree 100%; that's why I asked ;)
Will move forward with ExtractText.

Andy

Hi Andrew,
The existing equivalent as of now in base processors is ExtractText (it
uses regex to extract data from the content and assigned the result to
attributes). This is probably a good idea to follow the same approach if
possible?
