Name: Building applications on Lakebase: Postgres, Databricks Apps and AI in one place
Start: 2026-09-19T01:00:00.000Z
Location: 1530 East Williams Field Road

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.

6:40 Building on Lakebase, live
7:30 Questions, war stories, and what you'd like next

**Who it's for**

Application developers, data engineers and architects in the Phoenix metro, on Databricks or considering it. If you run Postgres today and have been asked how it fits with the lakehouse, this is the session.
