  <!--Hide setup

  from influxdb_client_3 import InfluxDBClient3

  client = InfluxDBClient3(host=f"{{< influxdb/host >}}",
      database=f"DATABASE_NAME", token=f"DATABASE_TOKEN")

  ```python
  # Example: Write and query data

  # Write sensor data in batches from a CSV file to a database
  client.write_file(file='./data/home-sensor-data.csv',
      timestamp_column='time',
      tag_columns=["room"])

  # Execute a query and retrieve data from the last 90 days
  table = client.query(
      '''SELECT *
         FROM home
         WHERE time >= now() - INTERVAL '90 days'
         ORDER BY time''')

  # This script assumes the client object is correctly configured
  # with your database name, token, and host URL. 
  # After the script runs, the table variable contains the data
  # formatted as a PyArrow table.
