      Snowflake Source Connector

      Snowflake

      Overview​

      The Snowflake source allows you to sync data from Snowflake. It supports both Full Refresh and Incremental syncs. You can choose if this connector will copy only the new or updated data, or all rows in the tables and columns you set up for replication, every time a sync is run.

      This Snowflake source connector is built on top of the source-jdbc code base and is configured to rely on JDBC 3.13.22 Snowflake driver as described in Snowflake documentation.

      Resulting schema​

      The Snowflake source does not alter the schema present in your warehouse. Depending on the destination connected to this source, however, the result schema may be altered. See the destination's documentation for more details.

      Features​

      Getting started​

      Requirements​

      1. You'll need the following information to configure the Snowflake source:
      2. Host
      3. Role
      4. Warehouse
      5. Database
      6. Schema
      7. Username
      8. Password
      9. JDBC URL Params (Optional)
      10. Create a dedicated read-only Airbyte user and role with access to all schemas needed for replication.

      Setup guide​

      1. Additional information about Snowflake connection parameters could be found here.​

      2. Create a dedicated read-only user with access to the relevant schemas (Recommended but optional)​

      This step is optional but highly recommended to allow for better permission control and auditing. Alternatively, you can use Airbyte with an existing user in your database.

      To create a dedicated database user, run the following commands against your database:

       

      -- set variables (these need to be uppercase)

      SET AIRBYTE_ROLE = 'AIRBYTE_ROLE';

      SET AIRBYTE_USERNAME = 'AIRBYTE_USER';




      -- set user password

      SET AIRBYTE_PASSWORD = '-password-';




      BEGIN;




      -- create Airbyte role

      CREATE ROLE IF NOT EXISTS $AIRBYTE_ROLE;




      -- create Airbyte user

      CREATE USER IF NOT EXISTS $AIRBYTE_USERNAME

      PASSWORD = $AIRBYTE_PASSWORD

      DEFAULT_ROLE = $AIRBYTE_ROLE

      DEFAULT_WAREHOUSE= $AIRBYTE_WAREHOUSE;




      -- grant Airbyte schema access

      GRANT OWNERSHIP ON SCHEMA $AIRBYTE_SCHEMA TO ROLE $AIRBYTE_ROLE;




      COMMIT;

      You can limit this grant down to specific schemas instead of the whole database. Note that to replicate data from multiple Snowflake databases, you can re-run the command above to grant access to all the relevant schemas, but you'll need to set up multiple sources connecting to the same db on multiple schemas.

      Your database user should now be ready for use with Airbyte.

      Authentication

      There are 2 ways of OAuth supported: Login / Password and OAuth2.​

      Login and Password​

      OAuth 2.0​

      Network policies​

      By default, Snowflake allows users to connect to the service from any computer or device IP address. A security administrator (i.e. users with the SECURITYADMIN role) or higher can create a network policy to allow or deny access to a single IP address or a list of addresses.

      If you have any issues connecting with Airbyte Cloud please make sure that the list of IP addresses is on the allowed list

      To determine whether a network policy is set on your account or for a specific user, execute the SHOW PARAMETERS command.

      Account 

         SHOW PARAMETERS LIKE 'network_policy' IN ACCOUNT;

      User 

         SHOW PARAMETERS LIKE 'network_policy' IN USER <username>;
