Shutdown and Draining

The default behavior of most SDKs is to send out events over the network asynchronously in the background. This means that some events might be lost if the application shuts down unexpectedly. The SDKs provide mechanisms to cope with this.

The Python SDK automatically drains on shutdown unless the AtExitIntegration is removed or the shutdown_timeout config key is set to 0. To manually drain the client provides a close method:

from sentry_sdk import Hub

client = Hub.current.client
if client is not None:
    client.close(timeout=2.0)

After a call to close, the client cannot be used anymore. It's important to only call close immediately before shutting down the application.

Alternatively, the flush method drains the event queue while keeping the client enabled for continued use.
