This is the implementation of the SingleStore data handler for MindsDB. SingleStore is a proprietary, cloud-native database designed for data-intensive applications. A distributed, relational, SQL database management system that features ANSI SQL support. It is known for speed in data ingest, transaction processing, and query processing.

​
Prerequisites

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

​
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.
There are several optional arguments that can be used as well.
  • ssl is the ssl parameter value that indicates whether SSL is enabled (True) or disabled (False).
  • ssl_ca is the SSL Certificate Authority.
  • ssl_cert stores SSL certificates.
  • ssl_key stores SSL keys.

​
Usage

In order to make use of this handler and connect to the SingleStore database in MindsDB, the following syntax can be used: 
CREATE DATABASE singlestore_datasource
WITH
  ENGINE = 'singlestore',
  PARAMETERS = {
    "host": "127.0.0.1",
    "port": 3306,
    "database": "singlestore",
    "user": "root",
    "password": "password"
  };
You can use this established connection to query your table as follows: 
SELECT *
FROM singlestore_datasource.example_table;
