RisingWave dialect for SQLAlchemy

RisingWave dialect for SQLAlchemy

SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL. https://www.sqlalchemy.org/

RisingWave is a cloud-native streaming database that uses SQL as the interface language. It is designed to reduce the complexity and cost of building real-time applications. https://www.risingwave.com

Prerequisites

For psycopg2 support you must install either:

• psycopg2, which has some prerequisites of its own.

• psycopg2-binary

(The binary package is a practical choice for development and testing but in production it is advised to use the package built from sources.)

Install

Install via PyPI

pip install sqlalchemy-risingwave

Recommend install packages locally like below. If directly from PyPI, the version may not be the most updated.

python setup.py sdist bdist_wheel # generate dist
pip install -e . # install this package

Usage

sqlalchemy-risingwave will work like a plugin to be placed into runtime sqlalchemy lib, so that we can overrides some code path to change the behaviour to better fits these python clients with RisingWave.

See how to use with Superset: doc

Develop

Install pre-req.

pip install sqlalchemy alembic pytest psycopg2-binary

Test

We use pytest for unittest.

pytest # to run the test
