["Duan, Jiangang" <jiangang.duan@xxxxxxxxx>]

Some of our customers are interested in Erasure code than tri-replicate to save disk space.
We propose a BP "Light weight Erasure code framework for swift", which can be found here https://blueprints.launchpad.net/swift/+spec/swift-ec
The general idea is to have some daemon on storage node to do offline scan - select code object with big enough size to do EC. 

Will glad to hear any feedback on this.
