Background Tasks

Feature Overview

Background tasks handle processes that are not suitable to complete synchronously in the foreground. They usually support:

• Document parsing
• Vectorization processing
• Notification sending
• Scheduled process execution

Use Cases

Suitable for:

• Batch or time-consuming processing tasks
• Automated jobs that need scheduled execution
• Background processing paths where frontend users should not wait for completion

Prerequisites

Before you start, we recommend preparing:

• Clear task inputs and outputs
• Whether asynchronous execution can tolerate delay
• Failure retry and monitoring methods

Steps

Step 1: First determine which tasks should be asynchronous

In general, tasks that take a long time, depend on external systems, or need batch execution are more suitable for background tasks.

Step 2: Distinguish immediate asynchronous tasks from scheduled tasks

First determine whether the task belongs to:

• Asynchronous execution immediately after an event trigger
• Running by Cron or on a fixed cycle

Step 3: Validate task status and results

Focus on confirming:

• Whether the task is created successfully
• Whether status transitions correctly
• Whether failures are traceable

Step 4: Connect monitoring and retry strategies

Background tasks are suitable for long-term running only when monitored. We recommend considering these at the same time:

• Failure retries
• Timeout handling
• Alert notifications

Result Validation

When the background task path is usable, it should at least achieve:

• Tasks can be triggered
• Status changes are visible
• Both successful and failed results can be traced

Value Description

The value of background tasks is decoupling time-consuming capabilities from the foreground experience, allowing the platform to both respond to users and complete heavy processing tasks.

Notes

• Asynchronization does not mean results do not need validation, status tracking is equally critical
• Scheduled tasks should have at least one manual rehearsal before launch
• If background task failures are invisible, issues will accumulate over time
