snowbim 1.0.12

A package to refresh power bi model .bim file

snowbim

This is to do something awesome between snowflake database and Power BI tabular model file (.bim).

Those are:

• Refresh tables (key: name)
• Refresh table's columns (key: name)
• Refresh table's partitions (key: name)

Supported Models:

• Compatibility Level: 1550
• Default Power BI Data Source Version: powerBI_V3

We make use of dbt (data build tool)'s profile to configure the Snowflake connection.

Therefore, PLEASE MAKE SURE you've already managed to create 1 dbt profiles.yml file.

Installation:

python -m pip install snowbim --upgrade

# dependencies
python -m pip install snowflake-connector-python[pandas]

# check version
python -m snowbim --version

Usage

python -m snowbim --help

If you don't use --profile-dir argument, by default, it will look for profiles.yml in the user home folder:

• Windows: %userprofile%/.dbt/profiles.yml
• Linux: ~/.dbt/profiles.yml

Sample commands:

• To create new model.bim file:

python -m snowbim --bim "/path/to/model.bim" --db "YOUR_SF_DB_NAME" --schema "YOUR_SF_SCHEMA_NAME"
# model.bim will be created after above command

• To upgrade existing model.bim file:

python -m snowbim --bim "/path/to/model.bim" --db "YOUR_SF_DB_NAME" --schema "YOUR_SF_SCHEMA_NAME"
# model.bim will be overidden after above command

• To upgrade existing model.bim file but output to a new model_upgrade.bim file:

python -m snowbim --bim "/path/to/model.bim" --out "/path/to/model_upgrade.bim" --db "YOUR_SF_DB_NAME" --schema "YOUR_SF_SCHEMA_NAME"
# model_upgrade.bim will be created after above command

NOTE: If schema is up-to-date, .bim file will not be created or modified.
