Yeah, fair, totally get it. Wasn't aiming to spread FUD, and I know that FDB is a little hard to compare against... it is pretty magic with how it routes and shards :D (https://forums.foundationdb.org/t/keyspace-partitions-perfor...)

It was the DB, and it was rogue usage on May 10, so I'm standing by my original comment
Side note: "Autosharding" is largely a myth that unproven databases are touting. Sharding is complex and requires planning and control. Databases that start shuffling data round without oversight produce nasty surprises. Trying to be too magic is normally always a mistake with databases.
