Hi,<br>
<br>
I want to develop a video conversion service. My idea is to offer a
REST api and save all the conversion request in a database to track the
state of each process (pending, doing, done, error, etc.)<br>
<br>
I want to use this database table as a persistent queue and a twisted
daemon that takes its task from this table. This daemon has to take the
task, update the state of the task and do the work.<br>
<br>
How can I subscribe the twisted daemon to the database inserts?<br>
<br>
Is the thread pool a good approach to this problem?<br>
<br>
Do you know a more simple solution to this problem?<br>
<br>
Thank you.<br>
<br>
<br>
