New features¶

With this release, we are pleased to announce support for sending webhook notifications to the following systems:

Slack
Microsoft Teams
PagerDuty

Note

Snowflake does not send webhook notifications to external systems other than the ones listed above.

Triggered tasks — General availability¶

With this release, we are pleased to announce the general availability of triggered tasks.

With triggered tasks, your tasks only run when the related stream has new data. This simplifies a common customer use case for frequently polling a source with unpredictable availability of new data, and reduces latency by immediately processing when there is new data.

For more information, see Triggered Tasks.

SQL updates¶

GET_DDL function: Support for warehouses¶

With this release, we are pleased to announce support in the GET_DDL function for warehouses. You can call the GET_DDL function to get the DDL statement for recreating a warehouse.

For more information, see GET_DDL.

Data governance updates¶

Custom Data Classification — General availability¶

With this release, we are pleased to announce the general availability of Custom Classification.

Snowflake provides the CUSTOM_CLASSIFIER class in the SNOWFLAKE.DATA_PRIVACY schema to enable data engineers to extend Snowflake’s data classification capabilities based on their own knowledge of the data. You can define your own semantic category, specify the privacy category, and specify regular expressions along with a threshold to match column value patterns while optionally matching the column name.

For more information, see Custom Data Classification.

Data Classification of tables in a schema with Snowsight — General availability¶

With this release, we are pleased to announce the general availability of using Snowsight to classify tables in a schema. You can also select custom classifiers (instances) that you can access to classify your data and determine whether to automatically assign tags to columns after classifying data.
