From what I see Gelly is not really maintained or used anymore..do you think it could make sense to deprecate it and write a guide (on the documentation) about how to rewrite a Gelly app into a Statefun one?

Hi,

As you mentioned, Gelly Graph's are backed by Flink DataSets, and therefore
work primarily on static graphs. I don't think it'll be possible to
implement incremental algorithms described in your SO question.

Have you tried looking at Stateful Functions, a recent new API added to
Flink?
It supports arbitrary messaging between functions, which may allow you to
build what you have in mind.
Take a look at Seth's an Igal's comments here [1], where there seems to be a
similar incremental graph-processing use case for sessionization.

Cheers,
Gordon
