Patch Set 15: (1 comment) http://gerrit.cloudera.org:8080/#/c/3823/15/src/kudu/tablet/tablet_metadata.cc File src/kudu/tablet/tablet_metadata.cc: PS15, Line 313: DCHECK_EQ(table_id_, superblock.table_id()); : PartitionSchemaPB partition_schema_pb; : partition_schema_.ToPB(&partition_schema_pb); : DCHECK_EQ(superblock.partition_schema().SerializeAsString(), : partition_schema_pb.SerializeAsString()); : PartitionPB partition_pb; : partition_.ToPB(&partition_pb); : DCHECK_EQ(superblock.partition().SerializeAsString(), : partition_pb.SerializeAsString()); > I liked this idea, but it still doesn't prevent compat break if the wire fo I suppose we could change this to CHECK and just rely on upgrade / downgrade tests for coverage on this stuff, if we don't want release and debug builds to act differently. After all, this isn't a hot path. Dinesh, to your point: providing an Equals() method for the non-PB objects doesn't prevent forward-compatibility problems, you are right. These are just inherent issues we have to deal with and as far as I can tell, having upgrade tests are really the only way to avoid unforeseen compatibility problems. -- To view, visit http://gerrit.cloudera.org:8080/3823 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: If57617e22b41296b8d4e8ad131220f1ebb235019 Gerrit-PatchSet: 15 Gerrit-Project: kudu Gerrit-Branch: master Gerrit-Owner: Dinesh Bhat <din...@cloudera.com> Gerrit-Reviewer: Adar Dembo <a...@cloudera.com> Gerrit-Reviewer: Dan Burkert <d...@cloudera.com> Gerrit-Reviewer: Dinesh Bhat <din...@cloudera.com> Gerrit-Reviewer: Kudu Jenkins Gerrit-Reviewer: Mike Percy <mpe...@apache.org> Gerrit-Reviewer: Todd Lipcon <t...@apache.org> Gerrit-HasComments: Yes
