Heroku has released a new Neo4j Graph Database Add-On, making it a language polyglot platform. This add-on is now available to all registered beta-testers of the Heroku PAAS platform and can be used for free with the test plan. The Neo4j-Graph Database serves as a type of NOSQL datastore suited for interconnected data, storing content as nodes connected via relationships. It has constant time query characteristics for local data access, independent of data set size, making it suitable for highly dynamic domains. Provisioning a Neo4j Server instance can be done by adding the add-on to an application and is available through Heroku's command-line interface or configuration settings. The Neo4j Add-On contains features like backup and restore functionality, providing datasets for users to explore larger graphs right away. Additionally, it supports Ruby server-side extensions, allowing developers to extend behavior of the server in other languages than Java, using JRuby on the server to run rack-applications packaged as ruby gems.
