Scheduler
|
|
=========
|
|
|
|
.. module:: scrapy.core.scheduler
|
|
|
|
The scheduler component receives requests from the :ref:`engine
|
|
<component-engine>` and stores them into persistent and/or non-persistent data
|
|
structures. It also gets those requests and feeds them back to the engine when
|
|
it asks for the next request to be downloaded.
|
|
|
|
|
|
Overriding the default scheduler
|
|
================================
|
|
|
|
You can use your own custom scheduler class by supplying its full
|
|
Python path in the :setting:`SCHEDULER` setting.
