Announcing AGE, a multi-model graph database extension for PostgreSQL

AGE, a multi-model graph database extension for PostgreSQL has been announced. AGE is the successor to AgensGraph. AGE will offer the same integration of SQL and Cypher without users having to discard their existing solutions, allow for a cleaner integration of AGE with PostgreSQL’s robust collection of other extensions, and expand scalability without sacrificing performance.

AGE has been recently elected as an incubation podling project by the Apache Software Foundation (ASF). The project has been donated to ASF as an open-source initiative.

  • Support for numeric, edge, and path types.

  • Casting to a vertex ‘::vertex’ from an agtype object.
  • Casting to an edge “::edge’ from an agtype object.
  • Casting to a path ‘::path’ from an agtype array.

• Scalar Functions
  • Id, start_id, end_id, type,properties, head, last, length, size, startNode, endNode, timestamp, toBoolean, toFloat, toInteger, and coalesce.
