---------------------------------------

             Summary: Allow overriding default value for all types when retrieving ConfigOption
                 Key: FLINK-6638
                 URL: https://issues.apache.org/jira/browse/FLINK-6638
             Project: Flink
          Issue Type: Improvement
          Components: Configuration
            Reporter: Chesnay Schepler


Currently there exists no equivalent to {{Configuration#getString(ConfigOption<String> configOption, String overrideDefault)}} for types such as {{Integer}} or {{Boolean}}.

If you want to use a non-String {{ConfigOption}} you either have to resort to hacks, like taking the key and going through the non-ConfigOption path or comparing the result with the default value of the option.
