Hello dear community,
We are trying to upgrade our flink from 1.9 to 1.13, but it seems the same
job running in 1.13 cannot restore the checkpoint / savepoint created by
1.9.
The stacktrace looks like:
java.lang.Exception: Exception while creating StreamOperatorStateContext.

Hello Dawid
I'm interested in this discussion because I'm currently trying to upgrade
flink from 1.9 to 1.12 for a bunch of sql jobs running in production. From
what you said, this seems to be a risky operation which might corrupt the
states. Is there any recommendation to mitigate the risk?

It sounds like the jdbc driver's connection is closed somehow, and probably
has nothing to do with flink itself.
Maybe you could check if there's some settings on the db that could close
the connection after some inactivity, or otherwise it could be your network

readerFunction)).
But when it comes to a sql job, where should I look

Hello, folks
We are trying to use S3 for the checkpoint storage, and this involves some
secrets in the configuration. We tried two approaches to configure those
secrets:
- in the jvm application argument for jobmanager and taskmanager, such as
-Ds3.secret-key
- in the flink-conf.yaml file for jobm
