System Properties Comparison Cassandra vs. Datomic vs. GeoSpock vs. InterSystems Caché vs. Memgraph

Editorial information provided by DB-Engines

Name

GeoSpock seems to be discontinued. Therefore it will be excluded from the DB-Engines ranking.

Caché is a deprecated database engine which is substituted with InterSystems IRIS. It therefore is removed from the DB-Engines Ranking.

Description

Wide-column store based on ideas of BigTable and DynamoDB

Optimized for write access

Datomic builds on immutable values, supports point-in-time queries and uses 3rd party systems for durability

Spatial and temporal data processing engine for extreme data scale

A multi-model DBMS and application server

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

Primary database model
