This is the implementation of the InfluxDB data handler for MindsDB. InfluxDB is a time series database that can be used to collect data and monitor the system and devices, especially Edge devices.

​
Prerequisites

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

​
Implementation

The required arguments to establish a connection are as follows:
  • influxdb_url is the hosted URL of InfluxDB Cloud.
  • influxdb_token is the authentication token for the hosted InfluxDB Cloud instance.
  • influxdb_db_name is the database name of the InfluxDB Cloud instance.
  • influxdb_table_name is the table name of the InfluxDB Cloud instance.
Please follow this link to generate token for accessing InfluxDB API.

​
Usage

In order to make use of this handler and connect to the InfluxDB database in MindsDB, the following syntax can be used: 
CREATE DATABASE influxdb_source
WITH
    ENGINE = 'influxdb',
    PARAMETERS = {
        "influxdb_url": "<influxdb-hosted-url>",
        "influxdb_token": "<api-key-token",
        "influxdb_db_name": "<database-name>",
        "influxdb_table_name": "<table-name>"
    };
You can use this established connection to query your table as follows. 
SELECT name, time, sensor_id, temperature
FROM influxdb_source.tables
ORDER BY temperature DESC
LIMIT 65;
