+=================================
+Jobs: pausing and resuming crawls
+=================================
+
+Sometimes, for big sites, it's desirable to pause crawls and be able to resume
+them later.
+
+Scrapy supports this functionality out of the box by providing the following
+facilities:
+
+* a scheduler that persists scheduled requests on disk
+
+* a duplicates filter that persists visited requests on disk
+
+* an extension that keeps some spider state (key/value pairs) persistent
+  between batches
+
+Job directory
+=============
+
+To enable persistence support you just need to define a *job directory* through
+the ``JOBDIR`` setting. This directory will be for storing all required data to
+keep the state of a single job (ie. a spider run).  It's important to note that
+this directory must not be shared by different spiders, or even different
+jobs/runs of the same spider, as it's meant to be used for storing the state of
+a *single* job.
+
+How to use it
+=============
+
+To start a spider with persistence supported enabled, run it like this::
+
+    scrapy crawl somespider -s JOBDIR=crawls/somespider-1
+
+Then, you can stop the spider safely at any time (by pressing Ctrl-C or sending
+a signal), and resume it later by issuing the same command::
+
+    scrapy crawl somespider -s JOBDIR=crawls/somespider-1
+
+Keeping persitent state between batches
+=======================================
+
+Sometimes you'll want to keep some persistent spider state between pause/resume
+batches. You can use the ``spider.state`` attribute for that, which should be a
+dict. There's a built-in extension that takes care of serializing, storing and
+loading that attribute from the job directory, when the spider starts and
+stops.
+
+Here's an example of a callback that uses the spider state (other spider code
+is ommited for brevity)::
+
+    def parse_item(self, response):
+        # parse item here
+        self.state['items_count'] = self.state.get('items_count', 0) + 1
+
+Persistence gotchas
+===================
+
+There are a few things to keep in mind if you want to be able to use the Scrapy
+persistence support:
+
+Cookies expiration
+------------------
+
+Cookies may expire. So, if you don't resume your spider quickly the requests
+scheduled may no longer work. This won't be an issue if you spider doesn't rely
+on cookies.
+
+Request serialization
+---------------------
+
+Requests must be serializable by the `pickle` module, in order for persistence
+to work, so you should make sure that your requests are serializable.
+
+The most common issue here is to use ``lambda`` functions on request callbacks that
+can't be persisted.
+
+So, for example, this won't work::
+
+    def some_callback(self, response):
+        somearg = 'test'
+        return Request('http://www.example.com', callback=lambda r: self.other_callback(r, somearg))
+
+    def other_callback(self, response, somearg):
+        print "the argument passed is:", somearg
+
+But this will::
+
+    def some_callback(self, response):
+        somearg = 'test'
+        return Request('http://www.example.com', meta={'somearg': somearg})
+
+    def other_callback(self, response):
+        somearg = response.meta['somearg']
+        print "the argument passed is:", somearg
