CData Python Connector for AlloyDB

Overview

The CData Python Connector for AlloyDB allows developers to write Python scripts with connectivity to AlloyDB. The connector wraps the complexity of accessing AlloyDB data in an interface commonly used by python connectors to common database systems.

Key Features

A variety of WHL files or a single TAR.GZ file that accommodate several execution environments after installation with "pip install".
Supported for Python versions 3.8, 3.9, 3.10, and 3.11, within both Windows and Linux environments. Python 3.8, 3.9, and 3.10 distributions on Mac are also supported.
Write and execute SQL queries to fetch and update data in AlloyDB.
Custom dialect class that enables SQLAlchemy 1.3 and 1.4 to use this connector.

Getting Started

See Getting Started to install the connector to your python distribution and to create a basic connection to AlloyDB.

Using the Python Connector/Using from Tools

See Using the Connector for examples of executing basic SELECT, INSERT, UPDATE, DELETE, and EXECUTE queries with the module's provided classes.

See Using from Tools to connect AlloyDB data to tools such as Pandas or Petl.

SQLAlchemy ORM

SQLAlchemy can be leveraged to model the tables in AlloyDB with mapped classes. See From SQLAlchemy for instructions for configuring the Python connector with SQLAlchemy.

Pandas

Pandas' DataFrames can be used alongside the connector to generate analytical graphics. See From Pandas for a guide.

Schema Discovery
