Nifi 1.10.0-Using the new Stateless NiFi execution engine and command line

Question

Got this feature,and there are two execution engine now---STATELESS AND STATEFUL,but i am not sure which scenarios do they fit separately? When i wanna update one or more parameter conveniently,use steteless execution engine and command line?If i need to view the state of flow,use stateful execution engine in Nifi UI?

ANY HELP IS APPRECIATE!

Answer 1

The short answer: If you want to work interactively in Nifi and develop flows, perhaps define parameters, use the regular Nifi mode.

If you want to run normal flows in a cluster also use the regular Nifi mode.

However, if you have a very linear flow that meets certain restrictions (such as having only 1 source and sink and clearly defined configuration parameters), specifically don't want to acknowledge a message till it completed the flow, and don't want to run it on a cluster but with isolated resources... Then look into the stateless Nifi mode.
