Snowflake is a cloud data warehouse (CDW). Use Snaps in this Snap Pack to:
Insert, upsert, update, unload, execute, and delete records in Snowflake.
Query a specific Snowflake instance and return the requested records or keys.
Execute multiple queries.
Enable SCD2 to track the history of changes.
The following Snaps support AWS S3, Azure Blob, and Google Cloud Storage for external staging:
Snowflake - Bulk Load
Snowflake - Bulk Upsert
Snowflake - Unload
Supported Versions
This Snap Pack is tested with JDBC driver version 3.14.0.
As of November 8, 2023, the Snowflake Snap Pack is bundled with the default Snowflake JDBC driver v3.14.0.
As of November 1, 2023, Snowflake instances hosted on Google Cloud must use Snowflake JDBC driver v3.13.25 or higher. If you are using the default drivers bundled with Snowflake or ELT Snaps, your pipelines are not affected. If your Snowflake instances hosted on Google Cloud use older JARs, you must update the client drivers. Learn more.
For support of all geospatial data types, we recommend that you use our custom JDBC driver. Contact support@snaplogic.com for details.
Prerequisites
Snowflake JDBC driver JAR v3.0.0 or higher (tested and supported with the JDBC driver version 3.14.0).
For the GEOMETRY data type, JDBC driver JAR v3.13.28 or higher is required
During execution, data processing on Snaplex nodes occurs principally in-memory as streaming and is unencrypted. When larger datasets are processed that exceeds the available compute memory, the Snap writes Pipeline data to local storage as unencrypted to optimize the performance. These temporary files are deleted when the Snap/Pipeline execution completes. You can configure the temporary data's location in the Global properties table of the Snaplex's node properties, which can also help avoid Pipeline errors due to the unavailability of space. For more information, see Temporary Folder in Configuration Options.
Enhanced the Snowflake Snap Pack to handle full vector support, including schema generation and output compatibility with vector data types.

The Snowflake - Bulk Upsert Snap no longer supports values from an upstream input document in the Key columns field when the expression button is enabled. The value must remain constant throughout the Snap’s execution and now limits support for expressions to include only Pipeline parameters.
To avoid breaking your existing Pipelines that use a value from the input schema in the Key columns field, update the Snap settings to use an input value from Pipeline parameters instead.

Certifies the Snowflake Snap Pack against JDBC Driver version 3.12.3. Snowflake Execute and Multi-Execute Snaps may break existing Pipelines if the JDBC Driver is updated to a newer version.
With the updated JDBC driver (version 3.12.3), the Snowflake Execute and Multi-Execute Snaps' output displays a Status of "-1" instead of "0" without the Message field upon successfully executing DDL statements. If your Pipelines use these Snaps and downstream Snaps use the Status field's value from these, you must modify the downstream Snaps to proceed on a status value of -1 instead of 0.
This change in the Snap behavior follows from the change introduced in the Snowflake JDBC driver in version 3.8.1: "Statement.getUpdateCount() and PreparedStatement.getUpdateCount() return the number of rows updated by DML statements. For all other types of statements, including queries, they return -1."
