trait ExplicitUidInOperatorsSupport extends AnyRef

This trait helps to explicitly set uids for Flink's stateful operators. Regards to https://ci.apache.org/projects/flink/flink-docs-stable/ops/upgrading.html#matching-operator-state operator with state should has specified uid. Otherwise recovery of state could fail.

Currently this class sets up uids by default

You can disable this globally by adding: globalParameters { explicitUidInStatefulOperators: false } in your model config.
