Changes

We are using key pair / SSO external browser authorization to Snowflake. This PR adds support for those two authorization mechanisms. While SSO is likely not a long term strategy to ingest metadata I used it locally to test connectivity from my ingestion to Snowflake and to play with it locally. Happy to make any changes here as requested!

Relevant docs:

• Key pair:
  • https://docs.snowflake.com/en/user-guide/key-pair-auth.html
  • https://github.com/snowflakedb/snowflake-sqlalchemy/blob/e1141b8ddfbc499d1b813ae1b791a0559312e6cb/README.rst#key-pair-authentication-support
• External Browser
  • https://docs.snowflake.com/en/user-guide/admin-security-fed-auth-use.html#setting-up-browser-based-sso

Below are some example recipes similar to what we are using internally,

Key Pair:

source:
  type: snowflake
  config:
    # Coordinates
    host_port: my_snowflake.east-us-2.azure
    warehouse: "my_warehouse"

    # Credentials
    username: [email protected]
    role: "MY_METADATA_ROLE"
    authentication_type: 'KEY_PAIR_AUTHENTICATOR'
    private_key_password: ${PRIVATE_KEY_PASSWORD}
    private_key_path:/secrets/snowflake-private-key.p8

sink:
  type: "datahub-rest"
  config:
    server: "http://localhost:8080"

SSO / External Browser based:

source:
  type: snowflake
  config:
    # Coordinates
    host_port: my_snowflake.east-us-2.azure
    warehouse: "my_warehouse"

    # Credentials
    username: [email protected]
    role: "MY_METADATA_ROLE"
    authentication_type: 'EXTERNAL_BROWSER_AUTHENTICATOR'

sink:
  type: "datahub-rest"
  config:
    server: "http://localhost:8080"
