Laravel Haystack provides supercharged job chains for Laravel. It comes with powerful features like delaying jobs for as long as you like, applying middleware to every job, sharing data and models between jobs and even chunking jobs. Laravel Haystack supports every queue connection/worker out of the box. (Database, Redis/Horizon, SQS). It's great if you need to queue thousands of jobs in a chain or if you are looking for features that the original Bus chain doesn't provide. If you need to make hundreds or thousands of API calls in a row, can be combined with Spatie's Job Rate Limiter to keep track of delays and pause jobs when a rate limit is hit. If you need to batch import rows of data - each row can be a haystack job (bale) and processed one at a time. While keeping important job information stored in the database.
Features
- Low memory consumption as one job is processed at a time and the chain is stored in the database
- You can delay/release jobs for as long as you want since it will use the scheduler to restart a chain
- It provides callback methods like then, catch and finally
- Global middleware that can be applied to every single job in the chain
- You can store models and data that are shared with every job in the chain
- You can prepare a Haystack and dispatch it at a later time
