Snowflake as Target

Fivetran HVR supports integrating changes into Snowflake location. This section describes the configuration requirements for integrating changes (using Integrate and Refresh) into Snowflake location. For the list of supported Snowflake versions into which HVR can integrate changes, see Integrate changes into location in Capabilities.

HVR uses the Snowflake ODBC driver to write data into Snowflake during Continuous Integrate and Row-wise Refresh.

The preferred methods for writing data into Snowflake are using Burst Integrate and Bulk Refresh as they provide better performance. However, it is required to create staging files on a temporary location to perform Burst Integrate and Bulk Refresh. For more information about staging, see section Staging for Snowflake.

Due to technical limitations, external staging on Azure for Snowflake is not supported in the HVR releases since 6.1.5/3 to 6.1.5/9.
