bvaradar commented on issue #1009: [HUDI-308] Avoid Renames for tracking state transitions of all actions on dataset URL: https://github.com/apache/incubator-hudi/pull/1009#issuecomment-562254591 @vinothchandar @n3nash : Redid the migration handling and addressed your comments High-Level Changes since the previous review. 1. Hudi WriteConfig can be used to control timeline layout upgrade. Default will be to start avoiding renames in writer as soon as we deploy the new hudi jar on existing datasets. (unit-tests added) 2. Readers are assumed to upgrade before Writers 3. Added missing actions to archiving. Now, Archiving logs all states of each action 4. Changed some code in Cleaner Migration (cc @leesf - please take a look). If this is too painful to review, I will try to create a separate diff.
