Hello Joshua,
The budget alert will be triggered once your costs rise above the threshold you specify. However, as Alexis has explained, there are various factors that might affect ‘how quickly’ you will receive the alert. Same as the email you shared, the documentation [1] provides details on how to manage App Engine costs. Specifically, besides mechanisms such as setting the max number of instances, Budget Alerts, Pub/Sub, and Cloud Functions could be used to automatically disable your app when your costs exceed the threshold you specify. The documentation also provides steps on how to implement it with sample codes. Back to the issue of ‘Cloud Datastore Read Operations’ being too high, a possible solution is to leverage cache mechanism to avoid excessive operations. You may find more information from the topic [2]. Hope it helps.
