Joel Bernstein updated SOLR-9684:
---------------------------------
Description:
SOLR-9559 adds a general purpose *parallel task executor* for streaming
expressions. The executor() function executes a stream of tasks and doesn't
have any concept of task priority.
The scheduler() function wraps two streams, a high priority stream and a low
priority stream. The scheduler function emits tuples from the high priority
stream first, and then the low priority stream.
The executor() function can then wrap the scheduler function to see tasks in
priority order.
Pseudo syntax:
{code}
daemon(executor(scheduler(topic(tasks, q="priority:high"), topic(tasks,
q="priority:low"))))
{code}
