• Download sort_orders.zip
• Extract the archive to any folder within the ./config/live folder of your JobScheduler installation.
• The archive will extract the files included to a folder sort_orders. 
• You can store the sample files to a different folder, the solution does not make use of specific folder names.

Implementation

Components

• The solution implements a job sorter that can be added to the top of any job chain.
  • This job implements a spooler_process() function that suspends all incoming orders.
  • This job is configured for one task and with an idle timeout attribute, i.e. it executes incoming orders sequentually.
  • After the last order this job waits for the duration specified with the idle_timeout attribute for new orders. 
    • The idle timeout is configured by <job idle_timeout="10"> with the sorter job definition.
    • With the idle timeout being expired this job will execute its spooler_exit() function and will sort all orders that have previously been suspended.
      • Sorting is done in alphabetical order.
      • The orders are reinserted to the next job node that follows the sorter job in the job chain.
• The sample included makes use of a job chain job_chain1 that includes the job nodes for the sorter job and a hello job.
