CockroachDB is many cool things but not even remotely in a the same category as fdb in terms of the transaction rates it can deal with per unit cost and you wouldn’t be mapping complex data structures into cdb; it’s not what it is for.
They just aren't the same thing. It’s like comparing a binary tree to json. If you squint you can see how they could be similar but really aren’t.
