horizontal partitioning (by key range)

all tables are translated to an ordered KV store and then broken down into 64MB ranges, which are then used as replicas in RAFT

tables can be distributed across several files (horizontal partitioning); sharding through federation

managed transparently by AWS

selectable replication factor

Source-replica replication

Multi-source replication using RAFT

yes, but depending on the SQL-Server Edition
