Methods for storing different data on different nodes

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

data is dynamically stored/cached on the nodes where it is read/written

horizontal partitioning

none

horizontal partitioning

by range, hash, list or composite

Multi-source replication using RAFT

yes

Managed transparently by NuoDB

yes

sychronisation to multiple collections

Multi-source replication
Source-replica replication
