This is the implementation of the GreptimeDB data handler for MindsDB. GreptimeDB is an open-source, cloud-native time series database features analytical capabilities, scalebility and open protocols support.

​
Implementation

This handler is implemented by extending the MySQLHandler. Connect GreptimeDB to MindsDB by providing the following parameters:
  • host is the host name, IP address, or URL.
  • port is the port used to make TCP/IP connection.
  • database is the database name.
  • user is the database user.
  • password is the database password.
There are several optional parameters 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 GreptimeDB database in MindsDB, the following syntax can be used: 
CREATE DATABASE greptimedb_datasource
WITH
  engine = 'greptimedb',
  parameters = {
    "host": "127.0.0.1",
    "port": 4002,
    "database": "public",
    "user": "username",
    "password": "password"
  };
You can use this established connection to query your table as follows. 
SELECT *
FROM greptimedb_datasource.example_table;
