Apache AGE (incubating)

license badge release badge issue badge forks badge stars badge

Apache AGE is a PostgreSQL Extension that provides graph database functionality. AGE is an acronym for A Graph Extension, and is inspired by Bitnine's fork of PostgreSQL 10, AgensGraph, which is a multi-model database. The goal of the project is to create single storage that can handle both relational and graph model data so that users can use standard ANSI SQL along with openCypher, the Graph query language.


  • Apache AGE is currently being developed for the PostgreSQL 11 release and will support PostgreSQL 12 and 13 in 2021 and all the future releases of PostgreSQL.
  • Apache AGE supports the openCypher graph query language and label hierarchy.
  • Apache AGE enables querying multiple graphs at the same time. This will allow a user to query two or more graphs at once with cypher, decide how to merge them and get the desired query outputs.
  • Apache AGE will be enhanced with an aim to support all of the key features of AgensGraph (PostgreSQL fork extended with graph DB functionality).
