Re: How to get files after a condition has been met

[Matthew Hawkins]

The wait/notify pattern might work here too.

Wait the getfile and notify when the validatejson is stopped?

Using Nifi Registry 1.25.0 for with Nifi 2.0.0

[Tobias Kellermann]

Hello togehter,

I have a question of compatibility of nifi registry 1.25.0 with Nifi 2.0.

Can I use nifi registry 1.25.0  together with clients of 1.25 and 2.0.x ?

Because we have 2 supported version of our erp software which one runs with 
java 8  and the newer one with java 17.

So i must run the flow in to different nifi versions, because we use the nifi 
rest api to deploy the flow.

Thank you for your answer.

With regards

Tobias Kellermann

I think the easiest way to do the conditional fetch would be to use
ConsumeKafka (or something equivalent for this use case like ListenHttp)
and FetchFile.
