Chris Pettitt updated KAFKA-8888:
---------------------------------
Description: Currently if you try to read a key from the wrong instance
(i.e. the partition that the key is mapped to is owned by a different instance)
you get null and no indication you're reading from the wrong instance. It would
be nice to get some indication that the instance is the wrong instance and not
that the value for the key is null. (was: In the current design you query
streams metadata to determine where a key is currently hosted. However, it is
possible that the partition for the key migrates. In my own testing I get null
back when that happens and not an error indicating that the partition migrated.)
Issue Type: Improvement (was: Bug)
Priority: Minor (was: Major)
Summary: Possible to get null IQ value if reading from wrong instance
(was: Possible to get null IQ value if partition migrates)
> Possible to get null IQ value if reading from wrong instance
