This topic provides answers to common questions about working with Snowflake native Experimentation.

Before you begin setting up the Snowflake integration, read the [Snowflake data requirements](/docs/home/warehouse-native/snowflake-requirements). Then, follow the setup instructions in [Setting up the Snowflake integration](/docs/home/warehouse-native/snowflake-configure).

If you have further questions about the integration, read the sections below.

## Roles and permissions

The role permissions include:

* You must have the `ACCOUNTADMIN` role in Snowflake
* You must have a [LaunchDarkly role](/docs/home/account/roles) of Owner or Admin, or a custom role that allows the following actions:
  * [add and edit integrations](/docs/home/account/roles/role-actions#integration-actions)
  * [add destinations](/docs/home/account/roles/role-actions#destination-actions)
  * [add metric data sources](/docs/home/account/roles/role-actions#metric-data-source-actions)

## IP addresses

You must add to your allow list the following outbound IP addresses:

<View title="Developer">
  * `52.21.152.96/32`
  * `52.200.35.24/32`
  * `52.200.50.23/32`
  * `54.144.218.89/32`
  * `54.221.221.197/32`
  * `34.236.6.43/32`
</View>

<View title="EU docs">
  * `3.78.21.121/32`
  * `3.124.211.237/32`
  * `18.153.39.243/32`
  * `3.75.12.2/32`
  * `3.68.26.17/32`
  * `3.77.253.41/32`
</View>

For a full list of LaunchDarkly's public IP addresses, read [Public IP list](/docs/home/infrastructure/ip-list).

## Confirm your setup

If you have configured your setup correctly, you will observe your Snowflake dynamic tables being populated with data under the `LD_EXPERIMENTATION` database and `RESULTS_<project_env_key>` schema within the next few hours.

## Data transfer frequency

Snowflake Data Export runs an hourly job, on the hour, that publishes raw LaunchDarkly data in your Snowflake account. You can expect the new data to be available in your Snowflake account within 10-15 minutes after the hour.

## Updates to existing integrations

After your integration is set up, you cannot make further edits to it, and you cannot create a second integration using the same project/environment key. If you need to update any fields as part of the integration, you must delete the existing integration and start a new one.

### Delete existing integrations

Before you delete an existing integration, [stop any running experiments that use warehouse native metrics](/docs/home/experimentation/start-stop-exp#stop-experiment-iterations) that are using data from the integration.

When you delete an existing integration the service disconnects from your Snowflake account. However, LaunchDarkly does not delete any stored event data. The LaunchDarkly user interface (UI) will still display related event data in places like the [event explorer](/docs/home/metrics/view-incoming-events), the event selection dropdown when [creating a metric](/docs/home/metrics/create-metrics), and other areas where metric events are visible.

### Add new integrations

If you want to set up additional integrations for additional LaunchDarkly projects and environments, follow the same setup instructions for the additional integrations, including:

* [Creating a metric events source](/docs/home/warehouse-native/snowflake-requirements) corresponding to the new LaunchDarkly project and environment
* [Setting up Snowflake Data Export](/docs/integrations/data-export/snowflake) for the new LaunchDarkly project and environment
* [Configuring Snowflake native Experimentation](/docs/home/warehouse-native/snowflake-configure) for the new LaunchDarkly project and environment
