Partitioning methods

Methods for storing different data on different nodes

none

Sharding, horizontal partitioning

Offers an API for user-defined Map/Reduce methods

can be realized in PL/SQL

yes

with TiSpark Connector

Consistency concepts

Methods to ensure consistency in a distributed system

Immediate Consistency
