Adding a few more columns that I think we need to define: Case | Client version (A) | Server version (B) | Wire message (C) | Message stored in OM Raft log and DB (D) | Behavior before finalize (E) | Behavior after finalize (F) | Downgrade result (G) -- | -- | -- | -- | -- | -- | -- | -- 1 | New | Old | uses factor/type AND ReplicationConfig (first can be optional if server is known to be new) | store factor/type | | | server is old, no downgrade 2 | Old | Old | uses factor/type | store factor/type | Business as usual | Business as usual | server is old, no downgrade 3 | New | New | uses factor/type AND ReplicationConfig | store factor/type + ReplicationConfig | | | can be done until we store old factor/type everywhere (finalize) 4 | Old | New | uses factor/type | store factor/type + ReplicationConfig | | | factor/type is used to calculate ReplicationConfig, both can be stored G3 and G4 also need updates. -- This is an automated message from the Apache Git Service.
