Hi guys,
Janino works perfectly!
It allows to create entire classes on-the-fly and to use them.
Thank you a lot.
Cheers,
Giacomo

Hi Giacomo,
you could use Janino [1] to directly compile the code string into a class
and execute it. The program does not need to be shipped to the cluster if
all user functions are contained in the jar.

Hi Robert,
thanks for the reply.
I receive a JSON from my client interface, which contains the dataflow
description.
Then I parse that JSON and the parser creates a string which contains the
Flink code, as the user can modify the dataflow, the description can change
every time it calls "Execute Dat
Hi,
you have to make sure that the Flink classes are contained in your class
path.
Either add the flink-dist jar from the binary distribution to your class
path, or use maven to build the backend.jar as a fat jar.
Why are you generating a java class from your dataflows?
Isn't it easier to just ca
Hi guys,
I'm developing a dataflow client whose backend, exported as jar, allows
users to convert dataflows to a Flink file .java with some code inside. The
generated file naturally calls some classes I have in jar file, like
MapFunction, DataSet.
My question is:
How to compile the generated file
