Description

Current best practice when deploying Flink applications to production is to set a custom UID, using DataStream#uid, so jobs can resume from savepoints even if they job graph has been modified. Flink should contain a configuration that can allow users to fail submission if their program contains an operator without a custom UID; enforcing best practices similarly to #disableGenericTypes.
