Wencong Liu closed FLINK-32978.
-------------------------------
Release Note:
The RichFunction#open(Configuration parameters) method has been deprecated and
will be removed in future versions. Users are encouraged to migrate to the new
RichFunction#open(OpenContext openContext) method, which provides a more
comprehensive context for initialization.
Here are the key changes and recommendations for migration:
The open(Configuration parameters) method is now marked as deprecated.
A new method open(OpenContext openContext) has been added as a default method
to the RichFunction interface.
Users should implement the new open(OpenContext openContext) method for
function initialization tasks. The new method will be called automatically
before the execution of any processing methods (map, join, etc.).
If the new open(OpenContext openContext) method is not implemented, Flink will
fall back to invoking the deprecated open(Configuration parameters) method.
Resolution: Fixed
