Joel Bernstein updated SOLR-9684:
---------------------------------
    Description: 
SOLR-9559 adds a general purpose parallel task executor for streaming 
expressions. The executor() function simply executes a stream of tasks and 
doesn't have any concept of task priority.

The scheduler() function wraps a list of streams and prioritizes the iteration 
of the streams. This allows there to be different task queues with different 
priorities.

The executor() function can then wrap the schedule function to see tasks in 
priority order.

Pseudo syntax:
{code}
daemon(executor(scheduler(topic(), topic(), topic())))
{code}
