Configure the Snowflake integration

1. Navigate to the App Setting page and click the Integration tab.

2. Click +Add Native Integration and select Snowflake from the dropdown menu.

3. Complete the Host, Port, and Default Warehouse fields.

4. Enable Native Query Audit.

5. Enable Native Lineage and complete the following fields:

   • Ingest Batch Sizes: This setting configures the number of rows Immuta ingests per batch when streaming Access History data from your Snowflake instance.

   • Table Filter: This filter determines which tables Immuta will ingest lineage for. Enter a regular expression that excludes / from the beginning and end to filter tables. Without this filter, Immuta will attempt to ingest lineage for every table on your Snowflake instance.

   • Tag Filter: This filter determines which tags to propagate using lineage. Enter a regular expression that excludes / from the beginning and end to filter tags. Without this filter, Immuta will ingest lineage for every tag on your Snowflake instance.

6. Select Manual or Automatic Setup and follow the steps in this guide to configure the Snowflake integration

Trigger Snowflake lineage sync job

Prerequisite

Authenticate with the Immuta API.

Trigger the lineage job

The Snowflake lineage sync endpoint triggers the native lineage ingestion job that allows Immuta to propagate Snowflake tags added through lineage to Immuta data sources.

1. Copy the example and replace the Immuta URL and API key with your own.

2. Change the payload attribute values to your own, where

   • tableFilter (string): This regular expression determines which tables Immuta will ingest lineage for. Enter a regular expression that excludes / from the beginning and end to filter tables. Without this filter, Immuta will attempt to ingest lineage for every table on your Snowflake instance.

   • batchSize (integer): This parameter configures the number of rows Immuta ingests per batch when streaming Access History data from your Snowflake instance. Minimum 1.

   • lastTimestamp (string): Setting this parameter will only return lineage events later than the value provided. Use a format like 2022-06-29T09:47:06.012-07:00.

   curl -X 'POST' \
       'https://www.organization.immuta.com/lineage/ingest/snowflake' \
       -H 'accept: application/json' \
       -H 'Content-Type: application/json' \
       -H 'Authorization: 846e9e43c86a4ct1be14290d95127d13f' \
       -d '{
       "tableFilter": "MY_DATABASE\\MY_SCHEMA\\..*",
       "batchSize": 1,
       "lastTimestamp": "2022-06-29T09:47:06.012-07:00"
       }'

Next steps

Once the sync job is complete, you can complete the following steps:

• Register Snowflake data sources
