Hi, We see a need for enhancing Swift to support a federation of swift clusters such that a set of clusters can work as a unified namespace and allow control over placement between the clusters. This requires multiple extensions to swift.
To promote community inputs and work in this area, I have uploaded today https://github.com/davidhadas/Autosync. The uploaded autosync.py middleware allows working with two clusters as a single entity. It uses the container-sync mechanism but removes the need for the admin to configure each and every container with appropriate sync information and keys. This code was designed with multiple clusters in mind and assumes that there is a placement engine deciding which container is placed where (not included). As an alternative, configuration directives can be used to define the default placement (shown as an example configuration) Yet currently is is aimed only for a first case in which there is a primary and a backup (secondary) clusters. Much more work is needed to support a federation of clusters, yet this code may be useful to some even as is (with some cleanups etc). Anyone seeking to join and help push this direction forward is most welcomed.
