Snowflake Git

🆕 Now supported in Snowflake, see the official documentation.

Worksheet Versioning

Inspired by a snowflake developers maintained repository.

Git integration

The extension is designed to apply git versioning on worksheets while developing on Snowsight, fully taking advantage of its functionalities.
The following workflow is advised :

1. [Start session] Upload worksheet from local branch to a user Snowsight workspace
2. Test, update and validate on Snowsight
3. [End session] Update local branch with modified Snowsight worksheets

Installation

Entry points are accessible through a CLI once the package is installed. To install it, please follow the following steps :

# [Optional: Python virtual environement]
$ pyenv virtualenv 3.10.4 sf
$ pyenv activate sf

# [Mandatory: Pip install]
$ pip install -U pip
$ pip install sf_git==1.3.1

# [Check your installation]
$ sfgit --help

# [Should result in:]
# Usage: sfgit [OPTIONS] COMMAND [ARGS]...
# 
# Options:
#   --help  Show this message and exit.
# 
# Commands:
#   commit  Commit Snowsight worksheets to Git repository.
#   config  Configure sfgit for easier version control.
#   fetch   Fetch worksheets from user Snowsight account and store them in...
#   init    Initialize a git repository and set it as the sfgit versioning...
#   push    Upload locally stored worksheets to Snowsight user workspace.

Commands have been created to import/export (respectively fetch/push) snowsight worksheets to/from local.

Git configuration

Warning A git repository is necessary to manage worksheets. You can either use an existing one or create a new one.

To apply versioning to your worksheets, you need to configure Git information through the config command.

First, set git repository to be used:

# if you want to use an existing git repository
$ sfgit config --git-repo <path_to_git_repo>

# if you want to create a new one 
$ sfgit init -p <path_to_git_repo>

Then, set a location to save your worksheets within this git repository:

$ sfgit config --save-dir <path_to_worksheets_persistency_directory>

Authentication

Currently, two authentication modes are supported i.e. credentials (PWD) and single sign-on (SSO).

Commands requiring Snowsight authentication all have options to provide at command time. If you don't want to manually input them everytime, you can set them at Python/Virtual environement level with :

$ sfgit config --account <your_snowsight_account_id>
$ sfgit config --username <your_snowsight_login_name>
$ sfgit config --password <your_snowsight_password>  # unnecessary for SSO authentication mode

Account ID

[!WARNING]
The account ID to be configured is in the <account_name>.<region>.<cloud> format.

If you are unsure about how to retrieve it for your snowflake account, you can run this query:

SHOW REGIONS;

WITH 
    SF_REGIONS AS (SELECT * FROM TABLE(RESULT_SCAN(LAST_QUERY_ID()))),
    INFOS AS (SELECT CURRENT_REGION() AS CR, CURRENT_ACCOUNT() AS CA)
SELECT CONCAT(
        LOWER(INFOS.CA),
        '.',
        SF_REGIONS."region",
        '.',
        SF_REGIONS."cloud"
    ) AS account_id
FROM INFOS LEFT JOIN SF_REGIONS ON INFOS.CR = SF_REGIONS."snowflake_region";

Unfortunately, the region is not always the same in the SHOW REGIONS ouput. Please check and adapt the format comforming to the official documentation. For example, eastus2 for Azure should actually be east-us-2.

Usage

Import user worksheet locally :

$ sfgit fetch --username tdambrin --account-id my_account.west-europe.azure --auth-mode SSO

Commit you worksheets (or through git commands for more flexibility) :

$ sfgit commit --branch master -m "Initial worksheet commit"

Export user worksheets to Snowsight :

$ sfgit push --auth-mode SSO --branch master

Be creative

Use the package to fit your use case, versioning is a way to do many things.

Switch versions

Transfer worksheets to another account
