• 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. Even if your queue driver is SQS!
• It provides callback methods like then, catch and finally
• Global middleware that can be applied to every single job in the chain
• Delay that can be added to every job in the chain
• You can store and retrieve data/state that is accessible to every job in the chain.
• You can store the model for later processing.
