This is the implementation of the TiDB data handler for MindsDB. TiDB is an open-source NewSQL database that supports Hybrid Transactional and Analytical Processing workloads. It is MySQL-compatible and can provide horizontal scalability, strong consistency, and high availability.

​
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.
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/tidb_handler) and run this command: pip install -r requirements.txt.

​
Usage

In order to make use of this handler and connect to the TiDB database in MindsDB, the following syntax can be used: 
CREATE DATABASE tidb_datasource
WITH
  ENGINE = 'tidb',
  PARAMETERS = {
    "host": "127.0.0.1",
    "port": 4000,
    "database": "tidb",
    "user": "root",
    "password": "password"
  };
You can use this established connection to query your table as follows: 
SELECT *
FROM tidb_datasource.demo_table;
