ASF GitHub Bot commented on FLINK-10356: ---------------------------------------- NicoK commented on issue #6705: [FLINK-10356][network] add sanity checks to SpillingAdaptiveSpanningRecordDeserializer URL: https://github.com/apache/flink/pull/6705#issuecomment-431833695 Thanks for the review @zhijiangW. The `getDeserializationError()` method was indeed a bit hacky and misleading. I refactored the code so it is (hopefully) clearer but anyway easier to maintain. I hope you can continue the review with the tests so we can still get this into 1.7. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
