Configuring Keep Warm

By default, Beam is serverless, which means your applications will shut off automatically when they’re not being used.

You can control how long your containers are kept alive by using the keep_warm_seconds flag in your deployment trigger.

For example, by adding a keep_warm_seconds=300 argument to a REST API, your app will stay running for 5 minutes before shutting off:

@app.rest_api(
    keep_warm_seconds=300,
)
