I'm curious to know the motivation behind publicizing the project at this stage in development, as it seems like the key feature (distributed transactional storage engine) is quite far away on the road map.
Are there any design documents detailing its implementation? I checked the wiki but it didn't look like there was anything there. What alternatives were considered, and why were they abandoned?
Also, is there a concrete use case for which this system is being built? If so, what are some (publicly releasable) details about the use case, e.g. access patterns, data volume, etc.?
