Joel Bernstein updated SOLR-9417:
---------------------------------
Description:
The daemon expression currently runs until it's killed. This ticket will add a
new *terminate* parameter to the daemon expression that will allow the daemon
to shut itself down when it's finished processing a topic.
There are a couple of small changes that need to be made to allow the daemon to
terminate on it's own:
1) The daemon will need to be passed the Map of all daemons in the /stream
handler. This will allow the DaemonStream to remove itself from the Map when it
terminates.
2) Logic needs to be added for the daemon to exit it's run loop if the topic
signals it had a zero Tuple run. The *sleepMillis* value in the EOF Tuple can
be used for this purpose. If sleepMillis is greater then 0 then this signals a
zero Tuple run.
