Announcing AGE, a multi-model graph database extension for PostgreSQL
Posted on 2020-07-08 by Bitnine Global
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.
