Building applications on Lakebase: Postgres, Databricks Apps and AI in one place

Our first meetup, on the question we get asked most this year: if Databricks has its own transactional database now, what does an application built on it actually look like?
Lakebase is a managed Postgres registered in Unity Catalog, with lakehouse tables synced into it and the operational data living beside the analytics under one set of permissions. That collapses a stack most teams run as three systems and two copy jobs. This session builds one application on it, live, and is honest about the edges.

What we'll build and show

- The application's own tables in Lakebase, and what a Postgres developer keeps and gives up
- Synced tables: a lakehouse table arriving in Postgres for the app to read, and how fresh it is
- A Databricks App on top, running in the workspace under its own service principal
- An agent answering questions over the same data through AI Gateway, inheriting the user's Unity Catalog grants
- Genie for the questions nobody wrote a screen for
- Where the seams are: what's GA, what's still in preview, and when we'd keep a separate database

Who's presenting

Preetham Reddy, founder and CEO of TechFabric, with engineers from our Databricks team. TechFabric is a Databricks partner in Gilbert with 80 Databricks-certified engineers, and we run our own business on the platform.
