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
Info
The Snowflake Snap Pack supports Snowflake vectors, including schema generation and output compatibility with vector data types.
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

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."
