----------------------------------
Summary: Add position and magic number checks to record
(de)serializers
Key: FLINK-3462
URL: https://issues.apache.org/jira/browse/FLINK-3462
Project: Flink
Issue Type: Improvement
Reporter: Ufuk Celebi
In order to improve the debugging experience in case of serialization errors,
we can add further sanity checks to the deserializers:
- Check expected position in buffer in order to ensure that record boundaries
are not crossed within a buffer or bytes left unconsumed.
- Add magic number to record serializer and deserializer in order to check byte
corruption. We currently only have this on a per buffer level.
We will be able to use these checks to improve the error messages.
