Database-driven Job Chains
"Beautifully simple but powerful database-driven job chains!
Laravel Haystack is a package that allows you to have a job chain stored in the database. Since all of the jobs in the chain are in the database, memory usage is low and you can delay jobs for a long time or have long running jobs without risking using all your memory.
Laravel Haystack supports every queue connection/worker out of the box. (Database, Redis/Horizon, SQS)."
