Work Description: mxm commented on issue #9484: [BEAM-8157] Remove length
prefix from state key for Flink's state backend
URL: https://github.com/apache/beam/pull/9484#issuecomment-529086661
Thanks for testing. I've pushed an update. It was wrong to assume we could
simply strip the length prefix from the ByteBuffer, as it simply holds whatever
bytes the original coder produced. We need to perform an encoding round-trip to
recover the original key in `OUTER` encoding.
@tweise Could you please test again with the new update?
