Chunking Jobs

Sometimes it's useful to split up the processing of something into multiple jobs, like processing a large file or scraping data from a paginated API. Laravel haystack uses the Laravel Chunkable Job package and allows you to split a job up into chunks.


Firstly, install the laravel-chunkable-jobs package using Composer with the command below.

composer require sammyjo20/laravel-chunkable-jobs

Configuring Jobs

Next, just create a job, remove the handle method and extend the ChunkableHaystackJob class. It's important that you extend this class and not ChunkableJob as it will use Haystack's methods to keep processing on the same Haystack.

You do not need to add the StackableJob interface or Stackable trait since the ChunkableHaystackJob will already add this for you.


use Sammyjo20\ChunkableJobs\Chunk;
use Sammyjo20\LaravelHaystack\ChunkableHaystackJob;

class GetPageOfPokemon extends ChunkableHaystackJob implements ShouldQueue
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    public function defineChunk(): ?Chunk
        $response = Http::asJson()->get('');

    	$count = $response->json('count'); // 1154

    	return new Chunk(totalItems: $count, chunkSize: 1, startingPosition: 1);

    protected function handleChunk(Chunk $chunk): void
        $response = Http::asJson()->get(sprintf('', $chunk->limit, $chunk->offset));

    	$data = $response->json();

    	// Store data of response
