Hi everyone,I am looking for a method to connect Databricks to Snowflake so I can query and transform the data directly in a notebook. I specifically want to avoid methods that just perform a one-time copy of the tables into Databricks, as I need the...

Databricks Agent Memory brings an interesting new direction to building AI agents that can learn from past interactions.Recently, Databricks introduced Agent Memory, and I think this is an interesting step toward making AI agents more useful in every...
Worth knowing before anyone builds on it: the docs now mark the earlier managed memory store as deprecated and point new agents at the newer agent memory plus agent sessions, which Databricks runs on Lakebase for you. The self-managed Lakebase route ...

Hi @jakobhaggstrom, Thanks for the detailed write-up.You've read it correctly. Today, Unity Catalog Oracle connections, Lakehouse Federation and the Lakeflow Connect Oracle connectors don't support client-certificate or Oracle wallet (mTLS) authentic...
Hi,I recently started trying out the Genie App Builder first presented at DAIS. For this I created an app space and I wanted to connect my app to a lakebase project. But I can't seem to find any options to do this like it works with apps which are no...
