B2B SaaS clients often upload large files. Imagine a CSV with 100,000 rows.

Most developers make a mistake. They use a loop to send 100,000 separate background jobs. This creates problems.

If job number 45,000 fails, you have no way to tell the user. You cannot track progress. You cannot send a single email once the whole file finishes. The jobs are disconnected.

You need Laravel Job Batching to fix this.

The Solution: Bus::batch()

Job batching groups thousands of jobs into one unit. Laravel gives this unit a unique ID. Your frontend uses this ID to show a progress bar. It also provides hooks to handle success or failure.

How to implement it:

• Use a memory-safe generator to read your CSV.
• Chunk your data into manageable pieces.
• Use Bus::batch() to group the jobs.
• Use allowFailures() so one bad row does not stop the entire process.

The lifecycle hooks work like this:

• then(): Runs only if every job succeeds.
• catch(): Runs when the first error occurs.
• finally(): Runs when all jobs finish, even if some failed.

The Benefit for Users

Your React frontend can poll the batch ID. It shows a 0-100% progress bar. This turns a mysterious background task into a transparent experience.

The Engineering Value

You gain control over distributed tasks. You stop silent failures. You provide real-time data to your users. You ensure post-processing logic runs at the correct time.
