An enterprise scheduler for python (like quartz)

Question

I am looking for an enterprise tasks scheduler for python, like quartz is for Java. Requirements:

• Persistent: if the process restarts or the machine restarts, then all the jobs must stay there and must be fired after restarting.
• Jobs must enter and exit the scheduler in a transaction (i.e. if some database operation fail, in a database unrelated to the scheduler, then the job must not have exited or entered the scheduler).
• Scalability. Depends on the measure of success of the project, but I would prefer to know from the beggining that I am not starting from a dead end.
• Configurability: when tasks expire, how many can be fired simultaneously, etc.

Any recommendations? Is there something python specific, or is it possible (or even good) to interface to Quartz from python.

Answer 1

Is this what you're looking for?

We're using Sun Grid Engine, which is accessible through DRMAA, which happens to have Python bindings.
