Nifi - Python SDKs
Hi,
Can anyone point me to any sources or samples on how to use python SDK
(Google Analytics, Facebook etc offers client SDK to access their API)
inside NiFi.
Regards,
K'sub

Thank you Andy. I will go through the shell script concept via
ExecuteStreamCommand processor So that I can create my python venv and put
my code in a directory and invoke via shell script. So I don't need to
depend on Jython/Nifi JVM for execution.
If I come across any issues, I will post it here.
Regards,
K

You can use a number of processors to interact with Python. The ExecuteScript and InvokeScriptedProcessor components allow you to write Python (actually Jython) code and have it be executed by a JSR-223 script execution engine within the same NiFi JVM. This allows the script to be persisted in the NiFi flow directly and be reusable without external dependencies.
You can also use the ExecuteProcess or ExecuteStreamCommand processors to invoke shell commands, including calling an external Python script.
