Citus Data has announced
that its CitusDB
distributed database has been released, under an open-source license
as a
PostgreSQL extension. “First, Citus 5.0 now fully uses the
PostgreSQL extension APIs. In other words, Citus becomes the first
distributed database in the world that doesn’t fork the underlying
database. This means Citus users can immediately benefit from new features
in PostgreSQL, such as semi-structured data types (json, jsonb), UPSERT, or
when 9.6 arrives no more full table vacuums. Also, users can keep working
with their existing Postgres drivers and tools.
