Siddharth Wagle updated HDDS-3924:
----------------------------------
Labels: (was: upgrade-p0)
> Move away from proto serialization for RocksDB keys in Ozone
> ------------------------------------------------------------
>
> Key: HDDS-3924
> URL: https://issues.apache.org/jira/browse/HDDS-3924
> Project: Hadoop Distributed Data Store
> Issue Type: Task
> Reporter: Aravindan Vijayan
> Assignee: Aravindan Vijayan
> Priority: Blocker
>
> Currently there are a few places where we rely on protobuf serialization to
> convert the key type to byte array for a RocksDB column family 'key'.
> However, from the proto
> [documentation|https://developers.google.com/protocol-buffers/docs/encoding#implications]
> it looks like the serialization of proto is unreliable (especially across
> versions). If the byte[] got from proto serialization changes, this will be a
> problem since old keys will be unreadable.
> Thanks to [~arp] who helped unearth this problem.
