Cluster Federation

Registered by Alistair Coles on 2013-06-26

The goal of this work is to enable account contents to be dispersed across multiple clusters, motivated by (a) accounts that might grow beyond the remaining capacity of a single cluster and (b) clusters offering differentiated service levels such as different levels of redundancy or different storage tiers. Following feedback at the Portland summit, the work is initially limited to dispersal at the container level, i.e. each container within an account may be stored on a different cluster, whereas every object within a container will be stored on the same cluster.

Note that this is distinct from container sync in that objects are only stored in one container.
