> Transaction coordination is pretty different in FoundationDB than in 2PC-based systems. The job of determining which conflict ranges intersect is done by a set of internal microservices called "resolvers", which partition up the keyspace totally independently of the way it is partitioned for data storage.

Ok, per my other question that makes sense. Similar to FaunaDB except the "resolvers" (transaction processors) are themselves partitioned within a "keyspace" (logical database) in FaunaDB for high availability and throughput. But FaunaDB transactions are also single-phase and we get huge performance benefits from it.
