Sqlalchemy adapter for Firebolt

Project description

SQLAlchemy and Firebolt

firebolt-sqlalchemy

Unit tests Code quality checks Firebolt Security Scan Integration tests Coverage

The Firebolt dialect for SQLAlchemy. firebolt-sqlalchemy uses Firebolt's Python SDK which implements PEP 249.

Installation

Requires Python >=3.7.

pip install firebolt-sqlalchemy

Connecting

Connection strings use the following structure:

firebolt://{username}:{password}@{database}[/{engine_name}][?account_name={name}}]

engine_name is optional. If omitted, Firebolt will use the default engine for the database.

account_name is optional. If omitted a default account will be used for connection.

Examples:

firebolt://email@domain:password@sample_database
firebolt://email@domain:password@sample_database/sample_engine

If a different account name is required, it can be specified in the connection string

firebolt://email@domain:password@sample_database/sample_engine?account_name=my_account

To override the API URL (e.g. for dev testing):

export FIREBOLT_BASE_URL=<your_url>

If your password contains % or / characters they need to be sanitised as per https://docs.sqlalchemy.org/en/14/core/engines.html#database-urls

my_pass = "0920%/2"
import urllib.parse
new_pass = urllib.parse.quote_plus(my_pass)

Quick Start

import urllib.parse
from sqlalchemy import create_engine

password = urllib.parse.quote_plus("your_password_here")
engine = create_engine("firebolt://email@domain:" + password + "@sample_database/sample_engine")
connection = engine.connect()

connection.execute("CREATE FACT TABLE example(dummy int) PRIMARY INDEX dummy")
connection.execute("INSERT INTO example(dummy) VALUES (11)")
result = connection.execute("SELECT * FROM example")
for item in result.fetchall():
    print(item)

AsyncIO extension

import urllib.parse
from sqlalchemy import text
from sqlalchemy.ext.asyncio import create_async_engine

password = urllib.parse.quote_plus("your_password_here")
engine = create_async_engine("asyncio+firebolt://email@domain:" + password + "@sample_database/sample_engine")

async with engine.connect() as conn:

    await conn.execute(
        text(f"INSERT INTO example(dummy) VALUES (11)")
    )

    result = await conn.execute(
        text(f"SELECT * FROM example")
    )
    print(result.fetchall())

await engine.dispose()

Limitations

  1. Transactions are not supported since Firebolt database does not support them at this time.
  2. Parametrised calls to execute and executemany are not implemented.
