This is the implementation of the Vitess data handler for MindsDB. Vitess is a database solution for deploying, scaling, and managing large clusters of open-source database instances. It currently supports MySQL and Percona Server for MySQL. It’s architected to run as effectively in a public or private cloud architecture as it does on dedicated hardware. It combines and extends many important SQL features with the scalability of a NoSQL database.

​
Prerequisites

Before proceeding, ensure the following prerequisites are met:
  1. Install MindsDB locally via Docker or Docker Desktop.
  2. To connect Vitess to MindsDB, install the required dependencies following this instruction.
  3. Install or ensure access to Vitess.

​
Implementation

This handler is implemented by extending the MySQL 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.

​
Usage

In order to make use of this handler and connect to the Vitess server in MindsDB, the following syntax can be used: 
CREATE DATABASE vitess_datasource
WITH
  ENGINE = "vitess",
  PARAMETERS = { 
    "user": "root",
    "password": "",
    "host": "localhost",
    "port": 33577,
    "database": "commerce"
  };
You can use this established connection to query your table as follows: 
SELECT *
FROM vitess_datasource.product
LIMIT 10;
