This is the implementation of the OpenGauss data handler for MindsDB.

OpenGauss is an open-source relational database management system released with the Mulan PSL v2 and the kernel built on Huawei’s years of experience in the database field. It continuously provides competitive features tailored to enterprise-grade scenarios.


Before proceeding, ensure the following prerequisites are met:

  1. Install MindsDB locally via Docker or use MindsDB Cloud.
  2. To connect OpenGauss to MindsDB, install the required dependencies following this instruction.
  3. Install or ensure access to OpenGauss.


This handler is implemented by extending the PostgreSQL data handler.

The required arguments to establish a connection are as follows:

  • user is the database user.
  • password is the database password.
  • host is the host name, IP address, or URL.
  • port is the port used to make TCP/IP connection.
  • database is the database name.


In order to make use of this handler and connect to the OpenGauss database in MindsDB, the following syntax can be used:

CREATE DATABASE opengauss_datasource
  ENGINE = 'opengauss',
    "host": "",
    "port": 5432,
    "database": "opengauss",
    "user": "mindsdb",
    "password": "password"

You can use this established connection to query your table as follows:

FROM opengauss_datasource.demo_table
