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 3.14.1 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.


Full Refresh SyncYes
Incremental - Append SyncYes

Getting started


  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.

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 user password
SET AIRBYTE_PASSWORD = '-password-';


-- create Airbyte role

-- create Airbyte user

-- grant Airbyte schema access


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.


Login and Password

HostThe host domain of the snowflake instance (must include the account, region, cloud environment, and end with Example:
RoleThe role you created in Step 1 for Airbyte to access Snowflake. Example: AIRBYTE_ROLE
WarehouseThe warehouse you created in Step 1 for Airbyte to sync data into. Example: AIRBYTE_WAREHOUSE
DatabaseThe database you created in Step 1 for Airbyte to sync data into. Example: AIRBYTE_DATABASE
SchemaThe schema whose tables this replication is targeting. If no schema is specified, all tables with permission will be presented regardless of their schema.
UsernameThe username you created in Step 2 to allow Airbyte to access the database. Example: AIRBYTE_USER
PasswordThe password associated with the username.
JDBC URL Params (Optional)Additional properties to pass to the JDBC URL string when connecting to the database formatted as key=value pairs separated by the symbol &. Example: key1=value1&key2=value2&key3=value3

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.




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