Apache Flink

anyone know why pyflinks protobuf version is pinned at `&lt;3.18` for 1.15?

Most likely because there was another dependency that required a lower version of it

ah interesting yeah that would make sense since i think older versions allowed versions above this so it must be a transitive dep

Most likely yes, especially since Protobuf is used by so many things :sweat_smile:

And we usually don't do dependency upgrades in patch versions

Ah looks like this dependency might be the one <https://github.com/apache/flink/pull/20058|grpcio>

Yeah, I've been dealing with this in StateFun and Java for about a week now.  `StateFun` is pinned at `3.7.1` which has been an absolute nightmare.  I had to compile my Protos with the `3.7.1` protoc(much lower than `3.21.10` I was using). That got my Elasticsearch IO Module running.

But then I have a Remote Functions App in Java that I cannot get running due to `FunctionTo` not being present for some reason(another version conflict).

So far I've not heard any kind of answer as to this fiasco and it seems to extend through the Flink ecosystem.
