atexit doesn’t work properly in batch mode: "cannot schedule new futures after interpreter shutdown"

Hello,

Specifications

• Client Version: 1.41.0
• InfluxDB Version: 2.7.5
• Platform: Ubuntu 23.10

Code sample to reproduce problem

import atexit
from influxdb_client import InfluxDBClient, Point

influxdb = InfluxDBClient(url="...", token="...", org="...")

write_api = influxdb.write_api()


@atexit.register
def close():
    print("closing")
    write_api.close()
    influxdb.close()


write_api.write("<bucket>", record=Point("test_bf").field("test", 1))

Expected behavior

Expected output:

closing

Actual behavior

Actual output:

The batch item wasn't processed successfully because: cannot schedule new futures after interpreter shutdown
closing

As you can see the atexit handler is executed, but the error happens before.

Additional info

No response

Start with the provided Python reproducer and trace the batch write API's shutdown and atexit lifecycle. Reproduce the error on Ubuntu with the stated client and InfluxDB versions; done means the batch item is processed without the interpreter-shutdown error before the handler prints "closing".
