MatrixOne

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

MatrixOne is a future-oriented hyper-converged cloud and edge native DBMS that supports transactional, analytical, and streaming workloads with a simplified and distributed database engine, across multiple data centers, clouds, edges, and other heterogeneous infrastructures.

Implementation

This handler is implemented using PyMySQL, a Python library that allows you to use Python code to run SQL commands on the MatrixOne database.

The required arguments to establish a connection are as follows:

• user is the username associated with the database.
• password is the password to authenticate your access.
• host is the hostname or IP address of the database.
• port is the port through which TCP/IP connection is to be made.
• database is the database name to be connected.

There are several optional arguments that can be used as well.

• ssl indicates whether SSL is enabled (True) or disabled (False).
• ssl_ca is the SSL Certificate Authority.
• ssl_cert stores the SSL certificates.
• ssl_key stores the SSL keys.

If you installed MindsDB locally via pip, you need to install all handler dependencies manually. To do so, go to the handler’s folder (mindsdb/integrations/handlers/matrixone_handler) and run this command: pip install -r requirements.txt.

Usage

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

CREATE DATABASE matrixone_datasource
WITH
    engine = 'matrixone',
    parameters = {
        "user": "dump",
        "password": "111",
        "host": "127.0.0.1",
        "port": 6001,
        "database": "mo_catalog"
    };

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

SELECT *
FROM Matrixone_datasource.demo;
