partitioning by range, list and by hash

Automatic, metric affinity per node

horizontal partitioning, sharding with MySQL Cluster or MySQL Fabric

Replication methods

Multi-source replication using RAFT

Source-replica replication

configurable replication factor, datacenter aware

Multi-source replication
Source-replica replication
