Looks cool. I can't find any performance or benchmarks though. Anyone care to guess/ballpark what kind of write speeds single nodes might be able to handle?
There's a script in the Message DB codebase that will do some fairly rudimentary read and write performance measures for your Postgres deployment:
https://github.com/message-db/message-db/blob/master/databas...
It's run right on the database, so no network I/O or client implementation in the loop - which is inevitably non-representative of "real world" scenarios.
