DBMS > Amazon Redshift vs. Blazegraph vs. Coveo vs. FoundationDB vs. TempoIQ

System Properties Comparison Amazon Redshift vs. Blazegraph vs. Coveo vs. FoundationDB vs. TempoIQ

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.

Created as commercial project in 2013, FoundationDB has been acquired by Apple in March 2015 and was withdrawn from the market. As a consequence, the product was removed from the DB-Engines ranking. In April 2018, Apple open-sourced FoundationDB and it therefore reappears in the ranking.

TempoIQ seems to be decommissioned. It will be removed from the DB-Engines ranking.
