- Support diversified storage policies such as different levels of replication and low-latency containers
- Upgrade the Swift infrastructure to run using Debian jessie (or later)
- Allow rate-limited container operations for better isolation among Swift users and use cases
- Delete non-used/non-requested thumbnail sizes periodically to reclaim space
