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

horizontal partitioning (by hash, key, range, range columns, list, and list columns)

Sharding

yes, utilizing Spark Core
