please remove the label or in 7 days the issue will be deprioritized.

> Priority: Major
> Labels: stale-major
>
> 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.
