System Properties Comparison Dgraph vs. FoundationDB vs. Microsoft Azure Cosmos DB vs. Microsoft Azure SQL Database vs. OrigoDB

Editorial information provided by DB-Engines

Name

Created as commercial project in 2013, FoundationDB has been acquired by Apple in March 2015 and was withdrawn from the market.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.
