metabase-query 1.0.3

Metabase query API with any URL and easy to filter.

Metabase query

metabase-query is a Python package designed to simplify data retrieval from Metabase, specifically focusing on the Card Query API and Dataset API. This package allows data professionals to execute queries using URLs or SQL directly within their Python code, facilitating streamlined access to Metabase data.

Key features

• Flexible Data Retrieval: Retrieve data in any format supported by Metabase, including JSON, CSV, and XLSX.
• Simple Integration: Execute queries by simply inputting the question URL and Metabase session—no need to manually provide parameters.
• Consistent Results: JSON results maintain the same column order as displayed in the Metabase UI.
• Session Management: Automatically checks the availability of the Metabase session.
• Effortless Filtering: Easily apply filters to your queries using simple dictionaries.
• Error Handling: Supports automatic retries in case of server errors or slowdowns.
• Bulk Filter Support: Allows entering multiple filter values in a single request.
• Query Versatility: Supports both saved and unsaved questions, as well as SQL queries.
• Utilize asynchronous libraries: Send multiple requests concurrently to retrieve data efficiently.

Installation

To install the package, use the following pip command:

pip install --upgrade metabase-query

Usage

Basic Example

from metabase_query import Metabase

# Initialize the MetabaseQuery object
mb = Metabase(metabase_session='YourMetabaseSession')

# Query data using a Metabase question URL
url = 'https://your-domain.com/question/123456-example?created_at=past3months'
data = mb.query(url=url, format='json')

Table URL and Unsaved question URL

url = 'https://your-domain.com/question#eyJkYXRhc2V0X3F1ZXJ5Ijp7ImRhdGFiYXNlIjo2LCJxdWVyeSI6eyJzb3VyY2UtdGFibGUiOjQ4MzV9LCJ0eXBlIjoicXVlcnkifSwiZGlzcGxheSI6InRhYmxlIiwidmlzdWFsaXphdGlvbl9zZXR0aW5ncyI6e319'
data = mb.query(url=url, format='csv')

# Example saving data to a CSV file.
with open('data.csv', 'rb') as f:
    f.write(data)

Advanced Settings

mb = Metabase(metabase_session='YourMetabaseSession',  retry_errors=None, retry_attempts=3, limit_per_host=5, timeout=600, verbose=True, domain=None)

• metabase_session: Your Metabase Session.
• retry_errors: Set to None to retry on any error, or provide a list of specific errors to retry only for those. Default is None.
• retry_attempts: The number of retry attempts in case of an error. Default is 3; set to 0 to disable retries.
• limit_per_host: The maximum number of connections allowed per host. Default is 5.
• timeout: The timeout duration in seconds for each connection. Default is 600.
• verbose: Whether to print logs. Default is True.
• domain: Not required for URL-based queries, but mandatory for SQL queries. Default is None.

Working with Filters

Simple Filter

It will combine both filter in URL and filter dictionary. Priority filter dictionary if it exists on URL.

filter = {
    'order_id': [123456, 456789, 789012], # UNLIMITED values!!!
    'status': 'Completed'
}
data = mb.query(url=url, filter=filter, filter_chunk_size=5000)

• filter: A single dictionary or a list of dictionaries representing the filters.
• filter_chunk_size: For bulk filter values, the package will divide the values into manageable chunks for processing, then combine the results into a single dataset.

Single URL with Multiple Filters

filters = [
    {'created_at': '2024-08-01~2024-08-05'},
    {'created_at': '2024-08-06~2024-08-10'},
    {'created_at': '2024-08-11~2024-08-15'}
]

results = mb.query(url=url, filter=filters)

# Combine results if the datasets have the same columns
from metabase_query.utils import combine_results
data = combine_results(results=[r['data'] for r in results], format='json')

Multiple URLs

It can use with a filter dictionary if needed.

urls = [
    'https://your-domain.com/question/123456-example?created_at=2024-08-01~2024-08-05',
    'https://your-domain.com/question/123456-example?created_at=2024-08-06~2024-08-10',
    'https://your-domain.com/question/123456-example?created_at=2024-08-11~2024-08-15'
]
results = mb.query(url=urls)

URL List with Filter List

urls = [
    'https://your-domain.com/question/123456-example', # 1
    'https://your-domain.com/question/123456-example', # 2
    'https://your-domain.com/question/123456-example' # 3
]

filters = [
    {'created_at': '2024-08-01~2024-08-05'}, # For URL 1
    {'created_at': '2024-08-06~2024-08-10'}, # For URL 2
    {'created_at': '2024-08-11~2024-08-15'} # For URL 3
]

results = mb.query(url=urls, filter=filters)

Executing SQL Queries

sql = '''
SELECT * FROM your_table LIMIT 1000
'''

database = '1-presto'

data = mb.sql(sql=sql, database=database, format='json')

• sql: A single SQL query or a list of SQL queries.
• database: A single database ID or a list of database IDs corresponding to the SQL queries. Refer to the database slug in the browser for details.

Multiple SQL Queries

sql_1 = '''
SELECT * FROM your_table WHERE created_at BETWEEN DATE '2024-08-01' AND '2024-08-05'
'''

sql_2 = '''
SELECT * FROM your_table WHERE created_at BETWEEN DATE '2024-08-06' AND '2024-08-10'
'''

sqls = [sql_1, sql_2]

results = mb.sql(sql=sqls, database=database)
