System Properties Comparison Apache Cassandra vs. Blueflood vs. DataFS vs. GeoSpock vs. ScyllaDB

Editorial information provided by DB-Engines

Name

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

Description

Wide-column store based on ideas of BigTable and DynamoDB

Optimized for write access

Scalable TimeSeries DBMS based on Cassandra

All data is stored inside objects which are linked by so-called link attributes. Objects consist of classes which can be extended and de-extended at runtime. Graphs can be defined with a struct.

Spatial and temporal data processing engine for extreme data scale

Cassandra and DynamoDB compatible wide column store

Primary database model

Secondary database models

Vector DBMS

starting with release V5
