New Snowflake Features Released in September–November 2023

At our recent Snowday event, we announced a wave of Snowflake product innovations for easier application development, new AI and LLM capabilities, better cost management and more. If you missed the event or need a refresh of what was presented, watch any Snowday session on demand. Let’s dive into all new releases in September, October and November.  

Architecture Flexibility

Iceberg Tables – public preview

While many customers value the simplicity of fully managed storage and a single, multi-language and multi-cluster compute engine to power a variety of workloads, some customers prefer to manage their own storage using open formats, which is why we’ve added support for Apache Iceberg Tables. Iceberg Tables bring the easy management and great performance of Snowflake to data stored externally in an open source format. Iceberg Tables also make it easier and cheaper to onboard without requiring upfront ingestion. To give customers flexibility for how they fit Snowflake into their data architecture, Iceberg Tables can be configured to use either Snowflake or an external service such as AWS Glue as the table’s catalog to track metadata, with an easy, one-line SQL command to convert the table’s catalog to Snowflake in a metadata-only operation. Learn more about Iceberg Tables here.

Snowflake Horizon

Seamless data governance with a new user experience in Snowsight – general availability

Users can effortlessly explore objects of interest and perform essential actions—all without SQL. Whether assigning tags, implementing masking policies, or applying row access policies, the process is easy and simple. The intuitive dashboard provides seamless navigation to desired databases and schemas, offering detailed reporting on tags and policies and the ability to take immediate action to apply them.

More comprehensive security with additional platform protections

To further secure data, Snowflake is improving the manageability, troubleshooting and granular controls for security admins with the following features:

  • Network rules and network isolation for S3 stages (in public preview) for better management of network restrictions to Snowflake to enhance network security
  • Multiple SAML IDP support, authentication policy and identifier first flow (in public preview soon) to improve authentication
  • Database roles (generally available) to make access management easier while enhancing secured and flexible data sharing 

Learn more here.

More granular access management and governance on shared data with database roles – general availability

Database roles are a new Snowflake object type within a database. Privileges on securable objects within the same database can be assigned to database roles. Database roles provide ease of access management for database owners within a single account, while also allowing providers to have centralized governance over shared data when serving multiple consumers. It further reduces the attack surface on shared data by limiting the scope of access granted to roles and users on the consumer account. Learn more here

Intuitive UI for Replication and Client Redirect in Snowsight – public preview

You can now easily create and monitor replication groups, failover groups and connection objects in Snowsight without writing any SQL queries. Through the UI, you can select what objects you want to replicate, which target account you want to replicate to, and the schedule in which the replication refresh should occur. The monitoring experience also provides rich insights, making it easy to quickly identify and troubleshoot any errors, ensuring your Recovery Point Objectives are always met. Learn more here.

Cost Management

More effectively control and limit your spend with budgets – public preview

Budgets are now available across AWS, Azure, GCP and for VPS. This feature allows customers to set spending limits and receive notifications for Snowflake credit usage for either their entire Snowflake account or for a custom group of resources within an account. Learn more.

Easy access to billing usage statements – general availability

With this release, Snowflake customers can now use Snowsight to view and download their billing usage statements, starting with the July 2023 statement. The retention period will be 1 year. Learn more here

Data Pipelines

Improved processing for streaming data with Dynamic Tables – public preview

Streaming and CDC data can be challenging to handle. That’s why we built Dynamic Tables, currently in public preview. Dynamic Tables is a new table type that drastically simplifies continuous data pipelines for transforming both batch and streaming data, declaratively. In recent releases, we’ve rolled out a number of improvements to make it even more robust for customers.

Dynamic Tables can be refreshed on creation by default, including those with a downstream lag. Sharing capabilities have been added, allowing for easier collaboration. Snowflake has also enabled support for granting privileges on all or future Dynamic Tables, including bulk grants. Learn more here

Ingesting data is even easier with improved Snowpipe auto-ingest and schematization – general availability

Several recent releases will make streaming and batch ingestion easier for Snowflake customers.

Snowpipe now supports cross-platform auto-ingest for Snowflake accounts hosted on any supported cloud platform. Customers can trigger  automated Snowpipe data loads using S3 event messages, GCS Pub/Sub event messages, and Azure Event Grid messages. Learn more.

Onboarding data is easier than ever with the latest schema detection and schema evolution capabilities, both of which are also now generally available. The schema detection feature for JSON and CSV uses the INFER_SCHEMA function to automatically detect the schema in a set of staged data files and retrieve the column definitions. The INFER_SCHEMA function applies to the following file formats: Apache Parquet, Apache Avro, ORC, JSON and CSV. Learn more

In addition, the structure of tables in Snowflake can now evolve automatically to support the structure of new data received from the data sources. Snowflake allows adding new columns or dropping the NOT NULL constraint from columns missing in new data files. Learn more.


Improved pipeline observability with task graph – public preview

Snowflake has improved capabilities for data engineers to more easily monitor and debug data pipelines. With task graph, you can review and run history to identify critical failing tasks that prevent a graph from completing, long-running tasks, inefficient task graphs, and other monitoring and debugging cases. 

Snowflake Alerts for better monitoring and debugging – general availability

A Snowflake Alert is a schema-level object that you can use to send a notification or perform an action when data in Snowflake meets certain conditions. For example, you can set up a Snowflake Alert to send a notification or perform an action when:

  • The warehouse credit usage increases by a specified percentage of your current quota. 
  • The resource consumption for your pipelines, tasks, materialized views, etc., increases beyond a specified amount.
  • Your data fails to comply with a particular business rule that you have set up.
