Ideal for development and testing. Requires Python 3.12 or 3.13 and databend-driver 0.34.0 or later:
pip install "databend-driver[local]>=0.34.0"
from databend_driver import connect
conn = connect("databend+local:///./local-state")
print(conn.query_row("SELECT 'Hello, Databend!'").values())
Run the full warehouse locally:
docker run -p 8000:8000 datafuselabs/databend
Databend's Sandbox UDF enables flexible agent orchestration with a three-layer architecture:
-- Define your agent logic
CREATE FUNCTION my_agent(input STRING) RETURNS STRING
LANGUAGE python HANDLER = 'run'
AS $$
def run(input):
# Your agent logic: LLM calls, tool use, reasoning...
return response
$$;
-- Orchestrate agents with SQL
SELECT my_agent(question) FROM tasks;
