Snowflake

Connect to a Snowflake data warehouse in AirOps

Remember to allowlist our IP Address 52.71.87.39

If your database is protected by a firewall, remember to allow inbound access to AirOPs IP address over your database port.

Basic Connection Parameters

  1. Account Identifier - the ID of your Snowflake Account.

    • If your Snowflake URL is https://**[en54071.us-east-2.aws](http://en54071.us-east-2.aws)**.snowflakecomputing.com/, then your account identifier is en54071.us-east-2.aws.

    • You can also find your Snowflake account ID by typing CURRENT_ACCOUNT() into a Snowflake worksheet and running it.

  2. User - the Snowflake user that AirOps will connect to the database with. It is best practice to create a new user for AirOps (instructions below), but any user with SELECT privileges can be used. Snowflake usernames are case sensitive.

  3. Warehouse - the Snowflake warehouse that AirOps will connect to.

  4. Database - database within the above Snowflake Warehouse.

  5. Role (Optional) - the Snowflake role to use for the connection. If not provided, we will use the default user's role.

Authentication Methods

AirOps supports two authentication methods for Snowflake connections:

Username & Password Authentication

Password - password for the above user.

Key Pair Authentication (Recommended)

Key Pair authentication provides enhanced security and is required when MFA is enabled on your Snowflake account.

Private Key - Your RSA private key in PEM format (see setup instructions below).

Private Key Passphrase (Optional) - Only required if your private key is encrypted.

Setting up Key Pair Authentication

Step 1: Generate Key Pair

Open the command line in a terminal window.

Generate a private key. You can generate an encrypted version of the private key or an unencrypted version of the private key.

To generate an unencrypted version, you can execute one of the following commands:

openssl genrsa -out rsa_key.pem 2048
openssl genrsa 2048 | openssl pkcs8 -topk8 -inform PEM -out rsa_key.p8 -nocrypt

To generate an encrypted version (recommended), execute the command:

openssl genrsa 2048 | openssl pkcs8 -topk8 -v2 <ALGORITHM> -inform PEM -out rsa_key.p8

You can use different algorithms with the -v1 command line option. These algorithms use the PKCS#12 password-based encryption algorithm and allow you to use strong encryption algorithms like triple DES or 128-bit RC2. You can use the following encryption algorithms:

  • PBE-SHA1-RC2-40

  • PBE-SHA1-RC4-40

  • PBE-SHA1-RC2-128

  • PBE-SHA1-RC4-128

  • PBE-SHA1-3DES

  • PBE-SHA1-2DES

To use stronger encryption algorithms, execute the command:

openssl genrsa 2048 | openssl pkcs8 -topk8 -v2 -inform PEM -out rsa_key.p8

You can use different algorithms with the -v2 command line option. You can use the following encryption algorithms:

  • AES128

  • AES256

  • DES3

Step 2: Generate Public Key

From the command line, generate the public key by referencing the correct version of your generated private key. You can execute one of the following commands:

If you used the openssl genrsa -out rsa_key.pem 2048 command to create the private key, run:

openssl rsa -in rsa_key.pem -pubout -out rsa_key.pub

If you used the openssl genrsa 2048 | openssl pkcs8 -topk8 -inform PEM -out rsa_key.p8 -nocrypt command to create the private key, then run:

openssl rsa -in rsa_key.p8 -pubout -out rsa_key.pub

Step 3: Assign Public Key to Snowflake User

In a Snowflake worksheet, execute the command:

ALTER USER <USERNAME> SET RSA_PUBLIC_KEY='<PUBLIC_KEY>';

Replace <USERNAME> with your Snowflake username and <PUBLIC_KEY> with the contents of your public key file (excluding the -----BEGIN PUBLIC KEY----- and -----END PUBLIC KEY----- lines).

Step 4: Configure AirOps Connection

  1. Select "Key Pair Authentication" as your authentication method

  2. Copy and paste your private key into the "Private Key" field (include the -----BEGIN PRIVATE KEY----- and -----END PRIVATE KEY----- lines)

  3. If your private key is encrypted, enter the passphrase in the "Private Key Passphrase" field

  4. Complete the other connection fields and test your connection

Setup User and Role (for New Users)

To add a Snowflake database as a Data Source on AirOps, use an existing user or create a user with read access to the tables, views, and schemas you would like to access from AirOps:

1. Create AirOps Role

CREATE ROLE IF NOT EXISTS AIROPS_ROLE COMMENT = "Airops default role";

2. Create AirOps User and Assign Role

CREATE USER AIROPS_USER
	password = '<secure-password>'
	first_name = 'AirOps'
	last_name = 'User'
	default_warehouse = '<warehouse>' 
	default_namespace = '<database>.<schema>'
	default_role = AIROPS_ROLE;

GRANT ROLE AIROPS_ROLE TO USER AIROPS_USER;
GRANT ROLE AIROPS_ROLE TO ROLE SYSADMIN;

3. Grant USAGE privileges to AirOps role

GRANT USAGE ON WAREHOUSE COMPUTE_WH TO ROLE AIROPS_ROLE;

GRANT USAGE ON DATABASE "<database>" TO ROLE AIROPS_ROLE;

GRANT USAGE ON ALL SCHEMAS IN DATABASE "<database>" TO ROLE AIROPS_ROLE;
GRANT USAGE ON FUTURE SCHEMAS IN DATABASE "<database>" TO ROLE AIROPS_ROLE;

GRANT SELECT ON ALL TABLES IN DATABASE "<database>" TO ROLE AIROPS_ROLE;
GRANT SELECT ON FUTURE TABLES IN DATABASE "<database>" TO ROLE AIROPS_ROLE;

GRANT SELECT ON ALL VIEWS IN DATABASE "<database>" TO ROLE AIROPS_ROLE;
GRANT SELECT ON FUTURE VIEWS IN DATABASE "<database>" TO ROLE AIROPS_ROLE;
