Collaborated with Snowflake to provide support for configuring Snowflake in Hevo using the Snowflake Partner Connect feature. Hevo can now be accessed from within the Snowflake platform, through which you can seamlessly set up an account and create data Pipelines with Snowflake as your Destination.

Snowflake offers a cloud-based data storage and analytics service, generally termed as data warehouse-as-a-service. Companies can use it to store and analyze data using cloud-based hardware and software.

In Snowflake, you can create both data warehouses and databases to store your data. Each data warehouse can further have one or more databases, although this is not mandatory. Snowflake provides you one data warehouse automatically when you create an account.

The Snowflake data warehouse may be hosted on any of the following Cloud providers:

  • Amazon Web Services (AWS)

  • Google Cloud Platform (GCP)

  • Microsoft Azure (Azure)

For Hevo to access your data, you must assign the required permissions. Snowflake uses Roles to assign permissions to users. You need ACCOUNTADMIN, SECURITYADMIN, or SYSADMIN privileges to create the required roles for Hevo. Read more about Roles in Snowflake.

The data from your Pipeline is staged in Hevo’s S3 bucket before being finally loaded to your Snowflake warehouse.

To connect your Snowflake instance to Hevo, you can either use a private link which directly connects to your Cloud provider through Virtual Private Cloud (VPC) or connect via a public network using your Snowflake account URL.

A private link enables communication and network traffic to remain exclusively within the cloud provider’s private network while maintaining direct and secure access across VPCs. It allows you to transfer data to Snowflake without going through the public internet or using proxies to connect Snowflake to your network. Note that even with a private link, the public endpoint is still accessible and Hevo uses that to connect to your database cluster.

Note: The private link is supported only for the Hevo platform regions.

Please reach out to Hevo Support to retrieve the private link for your cloud provider.

Handling Source Data with Different Data Types

For teams created in or after Hevo Release 1.58, Hevo automatically modifies the data type of a Snowflake table column to accommodate Source data with a different data type. Data type promotion is performed on tables that are less than 50GB in size. Read Handling Different Data Types in Source Data.

Note: Your Hevo release version is mentioned at the bottom of the Navigation Bar.

Destination Considerations

  • In Snowflake, when you use the conversion functions TO_VARCHAR() and TO_DATE() on a high-precision timestamp column, it returns the same output values for similar inputs. For example, both functions return the same output for the timestamp values 2023-01-01 12:00:00.000001 and 2023-01-01 12:00:00.000002. As a result, when you run a query containing any one of these conversion functions, you may see duplicate records in your Destination table.


  • Hevo replicates a maximum of 4096 columns to each Snowflake table, of which six are Hevo-reserved metadata columns used during data replication. Therefore, your Pipeline can replicate up to 4090 (4096-6) columns for each table. Read Limits on the Number of Destination Columns.
