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.

A graph consists of a set of vertices (also called nodes) and edges, where each individual vertex and edge possesses a map of properties. A vertex is the basic object of a graph, that can exist independently of everything else in the graph. An edge creates a directed connection between two vertices. A graph database is simply composed of vertices and edges. This type of database is useful when the meaning is in the relationships between the data. Relational databases can easily handle direct relationships, but indirect relationships are more difficult to deal with in relational databases. A graph database stores relationship information as a first-class entity. Apache AGE gives you the best of both worlds, simultaneously.

Apache AGE is:

Powerful -- AGE adds graph database support to the already popular PostgreSQL database: PostgreSQL is used by organizations including Apple, Spotify, and NASA. Flexible -- AGE allows you to perform openCypher queries, which make complex queries much easier to write. Intelligent -- AGE allows you to perform graph queries that are the basis for many next level web services such as fraud & intrusion detection, master data management, product recommendations, identity and relationship management, experience personalization, knowledge management and more.

Overview

This README file is for the Apache AGE PostgreSQL 12 release

  • Apache AGE is currently being developed for the PostgreSQL 11 and 12 releases and will support all the future releases of PostgreSQL.
  • Apache AGE supports the openCypher graph query language.
  • Apache AGE enables querying multiple graphs at the same time.
  • Apache AGE will be enhanced with an aim to support all of the key features of AgensGraph (PostgreSQL fork extended with graph DB functionality).
