### What’s New in Snowflake

#### New Features

- General Availability: Dynamic Tables, a new table type for continuous processing pipelines to be used. You‘’’re processing batch data daily or real-time data in minutes, dynamic tables allow you to create data pipelines that are easy to build, operate, and evolve, with GA delivering many new features sharing, Disaster recovery, better docs and observability, and Query evolution and SELECT \* support
- General Availability: Authentication enhancements: Authentication policies, control over how users authenticate by allowing you to specify which clients can authenticate and which authentication methods can be used with SAML2 and External OAuth security integrations
- General Availability: Authentication enhancements: Identifier-first login flow, identify a user before presenting authentication options. In this flow, Snowflake prompts the user for their email address or username only, then displays authentication options based on the identity of the user
- General Availability: Authentication enhancements: New properties for SAML2 security integrations, contains two new properties: ALLOWED\_USER\_DOMAINS and ALLOWED\_EMAIL\_PATTERNS and the user’s email address must match the values specified in these properties to authenticate with the identifier provider associated with the security integration. Identifier-first login needs to be enabled
- General Availability: Authentication enhancements: Multiple identity providers support using multiple identity providers for federated authentication using SAML2 security integrations, which allows different users to authenticate with different identity providers. Identifier-first login needs to be enabled.
- Preview: Snowflake Provider Studio allows you to work with all aspects of your Marketplace listings without needing to be an account administrator or a user with create listings privileges
- Preview: Snowflake Copilot in AWS us-east-1 and us-west-2, an LLM-powered assistant that simplifies data analysis while maintaining robust data governance and seamlessly integrates into your existing Snowflake workflow. You can ask open-ended questions about your data structure, send follow-up inquiries, or even use it to refine and improve your own SQL queries
- General Availability: New Region: AWS, EU (Zurich)
- General Availability: Budgets, account-level monitoring and notification of Snowflake credit usage for a group of specific Snowflake objects
- Preview: Access to Git repositories from Snowflake, fetch a full clone of your remote repository to a Snowflake repository stage

- General Availability: Snowflake Connector for ServiceNow V2, provides instant access to up-to-date ServiceNow data without needing to integrate against API endpoints or manage third-party solutions manually. Built on the Snowflake Native App Framework, the connector ingests data from ServiceNow into Snowflake automatically leveraging built-in security and reliability capabilities
- General Availability: New FAILOVER privilege for Client Redirect, enables promoting a secondary connection to serve as the primary connection. The privilege is granted to the ACCOUNTADMIN role by default, and this privilege can be granted to other roles to facilitate failover in a disaster recovery scenario. It’s still a Business Critical feature
- Preview: Managing Listings using SQL, this does not apply to paid, personalized listings, or listings on private data exchanges
- General Availability: Snowflake Connector for Google Analytics Raw Data and Snowflake Connector for Google Analytics Aggregate Data

### Conclusion

To put things in perspective for April, it took 2,400 words to describe all releases I could find for Snowflake this month. I did not cover 100% of things. To say Snowflake is trying to generally available many features is wishing thinking, and they are furiously going at it. What are they doing during the summit? Will there be any new announcements this year, or will we focus on learning to use all these beautiful features?

Worthy mentioned among many that Dynamic Tables, authentication enhancements, clean rooms, and new regions made it to GA. While Git integration and copilot went to Public Preview. I am going to try these soon and write an article.

I hope you continue to enjoy these articles.
