Minutes:
- JV ExplicitLAC is to be persisted, it happens during rolling restartes to lose that information and readers stall
- JV: should ExplicitLAC write failure trigger an ensemble change or be treated as a delayed write failure ?
- Enrico: we should consolidate reader side APIs for ExplicitLAC and PiggyBacked LAC
- JV: QoS in BookKeeper ?
- Latency sensitive vs Thoughtput sensitive applications
- Close to open consistency
- Backup, different priorities, different storage types
