Class ApiDeadlineMap

java.lang.Object

com.google.apphosting.runtime.ApiDeadlineMap

public class ApiDeadlineMap
extends Object

Default deadline maps for API calls, distinguishing between online and offline requests.

In App Engine, requests are treated as either 'online' or 'offline', with different request time limits and API call deadline limits applied to each.

An online request is a standard HTTP request from an end-user and must typically complete within 60 seconds.

An offline request is one that is not directly serving an incoming, user-initiated HTTP request and is allowed to run for a longer duration (e.g., 10 minutes or more). This typically includes background tasks such as:

• Task Queue tasks (from push or pull queues)
• Cron jobs

Because background tasks often perform long-running operations like data processing or batch updates, they require longer deadlines. This class provides separate deadline maps for API calls made during online vs. offline requests. For example, API calls like URL Fetch (urlfetch) or Cloud SQL (rdbms) have a much higher maximum deadline (e.g., 600 seconds) in the offline maps, allowing background tasks to complete long-running API calls without timing out.
