Name

Description

Wide-column store based on ideas of BigTable and DynamoDB

Optimized for write access

CockroachDB is a distributed database architected for modern cloud applications. It is wire compatible with PostgreSQL and backed by a Key-Value Store, which is either RocksDB or a purpose-built derivative, called Pebble.

An open source graph database built for real-time streaming and compatible with Neo4j

A lightweight, in-memory graph engine that serves as a reference implementation of the TinkerPop3 API

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

Sharding

dynamic graph partitioning

none

selectable replication factor

Representation of geographical distribution of servers is possible

Multi-source replication using RAFT

none

Eventual Consistency
Immediate Consistency

can be individually decided for each write operation

Immediate Consistency

none
