Data Flakes

Back

My feet hurt, my voice is gone, and I have accumulated 30 t-shirts. Snowflake Summit 2025 is a wrap!

It was an incredible week in San Francisco. While there were dozens of announcements, here are the Top 5 that will actually change your day-to-day job.

1. Cortex Agents (GA)#

The Keynote demo showed a user typing: “Find the root cause of the sales dip in Q1.” The Cortex Agent didn’t just write SQL. It:

  1. Queried SALES.
  2. Noticed a correlation with INVENTORY_LEVELS.
  3. Generated a chart.
  4. Emailed the Supply Chain manager.

Multi-step, autonomous agents are now real, and governed.

2. Unmanaged Iceberg Tables as Default#

Snowflake announced that for new accounts, creating a table can default to Iceberg format without user intervention. This signals a massive commitment to the open lakehouse architecture.

3. “Snowpipe Real-time”#

A successor to Snowpipe Streaming. It offers sub-second latency with transformations. You can now write Python streaming logic directly in the pipe, eliminating the need for a separate Apache Flink cluster for many use cases.

4. Native Apps with External Connectivity#

Native Apps can now securely talk to external APIs (Salesforce, Stripe, Slack) via a new governed egress gateway. This opens up the ability to build full-stack SaaS apps on Snowflake that aren’t isolated silos.

5. The “Visual SQL” Builder#

A new node-based UI in Snowsight for building queries. It looks like Alteryx or Informatica but compiles down to pure, optimized SQL. Great for the less code-heavy analysts on the team.

Conclusion#

The theme of 2025 was clear: “Actionable Data.” It’s no longer about just storing and reporting; it’s about agents and apps that do things.
