Installation

pip install deltastream-connector

Quick Start

import asyncio
from deltastream.api.conn import APIConnection

# Initialize connection with API token
auth_token = os.getenv("DELTASTREAM_AUTH_TOKEN")

if not auth_token:
    raise ValueError("Environment variable 'DELTASTREAM_AUTH_TOKEN' is not set")

# Use the token to construct the DSN and create the connection
dsn = f"https://:{auth_token}@api.deltastream.io/v2"
conn = APIConnection.from_dsn(dsn)

async def main():
    # Execute SQL queries
    rows = await conn.query("SELECT 1;")
    
    # Process results asynchronously
    async for row in rows:
        print(row)

if __name__ == '__main__':
    asyncio.run(main())

Authentication

The connector uses API token authentication. You can obtain an API token from the DeltaStream platform by running CREATE API_TOKEN api_token_name; using the console.
