The TICK Stack, which includes TICK (Time Series Database), is being used on the Google Cloud Platform for a real-time IoT project. The InfluxDB Python client library is utilized to interact with the database. Key points include importing the Python library, establishing a connection to the InfluxDB host, querying existing values, and writing records to the database using JSON data. The code initializes an InfluxDBClient object with the hostname and port, then uses it to query for temperature data and write new record data to the database. The result of the `write_points` method is a boolean value indicating success or failure.
