JFYI: some background for ICFC 2019 event:

> =================================================================================

> Paper registration and abstract: Nov 1st, 2018
> Full paper submission due: Nov 8th, 2018
> Notification of paper acceptance: Jan. 20th, 2019
> Workshop and tutorial proposals due: Nov 11, 2018
> Notification of proposal acceptance: Nov 18, 2018

So I have a draft of a positioning paper [0]... what missed that event :)

tl;dr: It is known that causal consistency is the best suitable for 
high-latency, high-scale and highly dynamic nature of membership in 
clusters... which is exactly what multiple autonomous control planes 
represent in edge clouds for post-MVP phases.

Even though the paper didn't make it for ICFC 2019 acceptance as I 
naively planned (not), hopefully we as community could find some use of 
it in future. Like collaboratively improving its contents, or making it 
readable by humans, then pushing it for other places for wider audience.
It's just free for any use, please go for it! :)

Or maybe we could prototyping something for OpenStack edge post-MVP 
cases out of SwiftCloud [1] just like the folks did for CockroachDB [2]? 
Note, while that github repo does not look super alive and driven by 
many contributions, that work looks really promising, you can read more 
for the theoretical fundamentals of it in "SwiftCloud: Fault-Tolerant 
Geo-Replication Integrated all the Way to the Client Machine" and 
"SwiftCloud: Write fast, read in the past: Causal consistency for 
client-side applications". That really buys to me to put it all 
client-sided at the edge and make it doing all geo-replication dances.

Ofc there is more for prototyping. For example, building some 
Bolt-on'ish shim middleware on top of any popular eventual consistent 
storage, like Riak (not sure there is opensource implementations for 
Bolt-on yet). Or trying something at api-to-api level for high-level 
synchronization with "delayed replication" of queued operations.

PS. @Pierre and @Adrien I gave it a quick glimpse into some of the 
sources you linked for the related work section of the positioning 
paper, thank you a lot for that and x1000 for authoring such things.
So the draft now almost hits the recommended limit of a 6 pages, so I 
think there should be pretty much it for a positioning paper.
