gyfora opened a new pull request, #938:
URL: https://github.com/apache/flink-kubernetes-operator/pull/938
## What is the purpose of the change
This PR adds support for the 2.0 preview release of Flink. As a necessary
prerequisite it also includes a bumping of the operator Flink dependency to
1.20.
The major incompatibility that was addressed here is related to the YAML
config handling. Flink 2.0 only supports the new standardized yaml runtime
config while 1.20 and older versions supported both the old and the new.
The operator previously only used the legacy flat yaml config. Now a new
logic has been put in place for Flink 2.0 and above to automatically convert
and use the new yaml configs.
