Hi Jakob, request-cancel would not work to clear the queue because the requests have not yet started and therefore do not have an ID. You need to restart the node that has the task server to clear the queue (or do something clever like Damon suggested to make it clear Real Fast).
There are some RFEs around providing more control of the task queue, and I put your comments there. Also remember, if you are using CPF and you "clear the queue" by restarting, CPF keeps a persistent state and remembers where you where, continueing processing after the restart, so careful of the whack-a-mole issue. -Danny -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Jakob Fix Sent: Tuesday, October 11, 2011 7:53 AM To: General MarkLogic Developer Discussion Subject: Re: [MarkLogic Dev General] how to purge the task server queue? Thanks Damon, we restarted the server. When you say "replace the invoked module with a no-op module" this will not remove tasks currently in the queue, correct? On a related note, could one write some code around xdmp:request-cancel() to purge the queue? In any case, I think it would be a useful addition to the api to be able to better control the task server. Many thanks for your answer, Jakob.
