For September, two of the founders of PipelineDB are going to be introducing this streaming PostgreSQL fork. Come learn what PipelineDB is about and how you'd use it alongside PostgreSQL. This meetup will be at a new venue, If(we), a social networking company which uses PostgreSQL together with internal databases. RSVP on meetup.
P.S. we are looking for a lightning talk for this meetup! Contact josh-at-postgresql.org.
