Description RHOS Integration 2013-12-12 16:52:02 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/swift/+spec/distributed-config.

Description:

What: 
Automate the distribution of files to the /etc/swift  of Swift servers.
This may include ring files as well as various configuration files. 
This enhancement ensures that configuration converges to be identical in a large population of servers. 

How: 
 - Use rsync for data transfer 
 - In the fault free scenario, design for a fast  global update to N servers, using only N updates, with each server updating two other servers, and the global update taking log(N) steps. 
 - Use a gossip algorithm for convergence after faults. 
 - Offer configurable randomized slowdown parameters to help control the global resources used by the update and synchronization.
