Open Lakehouses are among the most transformative innovations in big data, celebrated widely within data communities. Yet, for most product engineers, the lakehouse is off the radar.

We’ll also dive into our open-source project, pg_mooncake, which empowers developers to build and manage lakehouse tables directly from within PostgreSQL.
