The ways in which it can (and will) fail are monumentally complex. Everything looks simple when it working.

A distributed SQL database with the scalability of a KV store

b) be able to give up ad hoc queriesSo I guess if I ever need to build a highly scalable, fault tolerant, distributed todo list. I look into it. Not sure how I will aggregate data to run the dashboards that my MBAs will be up my butt about though. ActorDB arguably gives you the largest amount of query flexibility out of the new breed of databases, while still being strongly consistent and persistent (not memory only).
I also don mean to put down the creators of this product, it probably has its use cases. But every time I see something like "SQL with the scalability of KV" (which happens a lot these days), it like someone promising a perpetual energy source. Most problem sets fit quite well into the actor model and you can keep JOINs where it matters most (inside an actor).
How do you run a JOIN across a bunch of actors
So yet another database (for certain definitions of database) built for the tiny fraction of applications that will:a) warrant this kind of complexity
So can I create one actor for each of my clients, and add machines to my cluster and have them automatically balance across it? And I can do normal SQL queries Nike Jackets Windrunner

You can run queries across actors (even acid transactions), but not actual joins. :)It a great idea, but I think the "mission statement" needs to be restated.
Yes but then you stuck with a KV data and query model. It still being an SQL database is kind of besides the point since you not using it as a relational database.
I been meaning to try ActorDB out for a while now to see how well it performs on large data sets. IIRC, the basic premise is that every actor is a sqlite instance which causes some interesting limitations that might even Nike Long Sleeve Crop
