The page *Processing Queue* shows the current state of document
|
|
|
|
|
processing for your uploads.
|
|
|
|
|
|
|
|
|
|
At the top of the page a list of running jobs is shown. Below that,
|
|
|
|
|
the left column shows jobs that wait to be picked up by the job
|
|
|
|
|
executor. On the right are finished jobs. The number of finished jobs
|
|
|
|
|
is cut to some maximum and is also restricted by a date range. The
|
|
|
|
|
page refreshes itself automatically to show the progress.

You can cancel running jobs or remove waiting ones from the queue. If
|
|
|
|
|
you click on the small file symbol on finished jobs, you can inspect
|
|
|
|
|
its log messages again. A running job displays the job executor id
|
|
|
|
|
that executes the job.
|
|
|
|
|
|
|
|
|
|
Currently the job queue executes just the document processing tasks,
|
|
|
|
|
but it may be used for other long running tasks in the future.
|
|
|
|
|
|
|
|
|
|
Since job executors are shared among all collectives, it may happen
|
|
|
|
|
that a job is some time waiting until it is picked up by a job
|
|
|
|
|
executor. You can always start more job executors to help out.
|
|
|
|
|
|
|
|
|
|
If a job fails, it is retried after some time. Only if it fails too
|
|
|
|
|
often (can be configured), it then is finished with *failed* state. If
|
|
|
|
|
processing finally fails, the item is still created, just without
|
|
|
|
|
suggestions. But if processing is cancelled by the user, the item is
|
|
|
|
|
not created.
