Yes, you can make use of scheduled jobs which can process the job queue either one by one or in batches depending on your infrastructure setup.

There are two ways you can setup queuing mechanism: 

1- Make use of ActiveMQ 

2- Use repository based job queue (basically creating contentless nodes which job data in the repository, process them and delete/retain (for reporting) after job is processed)

Here is an example of creating scheduled jobs:
