Roman Grebennikov commented on FLINK-13414:
-------------------------------------------
I went further using [~NickBurkard] 's flink-adt scala3 PR, and cross-built a
forked version of Flink's Scala API:
[https://github.com/findify/flink-scala-api|https://github.com/findify/flink-scala-api.]
Check the github repo for details, but if you can afford re-bootstrapping your
job state from scratch, then migration is quite straightforward. Main features:
* Cross-built for Scala 2.12, 2.13 and 3.x
* 100% replica of the 1.15 Scala API, with deprecated methods removed.
* ClosureCleaner from Spark 3.x with 2.13 and java 17 support.
* Agnostic to the serialization format, but can use flink-adt to support scala
more natively.
It's still an experimental version which is not yet well tested, but I don't
see any possible dangers in it:
* we're using flink-adt exclusively for a lot of Flink jobs in Findify for
almost a year with no issues so far.
* Flink's Scala API is a thin wrapper on top of Java API, so there is nothing
to break.
The only not well-tested thing is scala3 derivation, which is a compile-time
process. So if you have compilation errors due to flink-adt failing for your
case classes, you're welcome to submit a bug report on github.
