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 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 scheduler function to see tasks in
priority order.
Pseudo syntax:
{code}
daemon(executor(scheduler(topic(), topic(), topic())))
{code}
