DBMS > Blazegraph vs. Microsoft Azure Cosmos DB vs. Oracle vs. TDSQL for MySQL vs. Teradata Aster

System Properties Comparison Blazegraph vs. Microsoft Azure Cosmos DB vs. Oracle vs. TDSQL for MySQL vs. Teradata Aster

Editorial information provided by DB-Engines

Name

Amazon has acquired Blazegraph's domain and (probably) product. It is said that Amazon Neptune is based on Blazegraph.

Teradata Aster has been integrated into other Teradata systems and therefore will be removed from the DB-Engines ranking.

Description

High-performance graph database supporting Semantic Web (RDF/SPARQL) and Graph Database (tinkerpop3, blueprints, vertex-centric) APIs with scale-out and High Availability.

Globally distributed, horizontally scalable, multi-model database service

Widely used RDBMS

A high-performance distributed database management system with features such as automatic sharding, intelligent operation and maintenance, elastic scalability without downtime, and enterprise-grade security. It is highly compatible with MySQL.
