David Handermann commented on NIFI-16399:
-----------------------------------------
Thanks [~mike.thomsen]. The extension approach I am evaluating is going a
different direction using the Java ScriptEngine, but enabling external
packaging and use of ScriptEngine implementations. One of the primary goals is
to keep all operations within the same JVM to provide a coherent way to manage
CPU and memory resources through the NiFi process.
