# Prerequisites

The following section describes the prerequisites for using Snowflake on Google as a Qlik Replicate target endpoint.

## Client prerequisites

Qlik Replicate for Windows:

Download and install Snowflake ODBC driver 2.25.3 (64-bit) or later for Windows on the Qlik Replicate Server machine.

Qlik Replicate for Linux:

Download and install Snowflake ODBC driver 2.25.3 (64-bit) or later for Linux on the Qlik Replicate Server machine.

Information note

The expected name for the ODBC driver is **SnowflakeDSIIDriver** (the default).

## Performance and Cloud Services usage optimization

In order to optimize both Snowflake Cloud Services usage and overall performance, it is strongly recommended to enable the [Apply batched changes to multiple tables concurrently](https://help.qlik.com/en-US/replicate/May2025/Content/Global_Common/Content/SharedEMReplicate/Customize%20Tasks/tasks_applychangtunestab.htm#batch_concuurent) option in the task settings' Change Processing Tuning tab.

## Storage integration name

You need to specify a storage integration name in the Snowflake on Google target endpoint settings. Integrations avoid the need for passing explicit cloud provider credentials such as secret keys or access tokens; instead, integration objects reference a Cloud Storage service account.

For more information on creating a storage integration name, see [Configuring an Integration for Google Cloud Storage](https://docs.snowflake.com/en/user-guide/data-load-gcs-config.html)

## Firewall prerequisites

Firewall port 443 needs to be opened for outbound communication.
