SQLAlchemy

The logfire.instrument_sqlalchemy() method will create a span for every query executed by a SQLAlchemy engine.

Installation

Install logfire with the sqlalchemy extra:

pipuvpoetry

pip install 'logfire[sqlalchemy]'

uv add 'logfire[sqlalchemy]'

poetry add 'logfire[sqlalchemy]'

Usage

Let's see a minimal example below. You can run it with python main.py:

main.py

import logfire
from sqlalchemy import create_engine

logfire.configure()

engine = create_engine("sqlite:///:memory:")
logfire.instrument_sqlalchemy(engine=engine)

The keyword arguments of logfire.instrument_sqlalchemy() are passed to the SQLAlchemyInstrumentor().instrument() method of the OpenTelemetry SQLAlchemy Instrumentation package, read more about it here.

Tip

If you use SQLModel, you can use the same SQLAlchemyInstrumentor to instrument it.
