Looks like there is no legal way to pause/continue crawling with Scrapyd, as it was with Scrapy itself (scrapy crawl spider -s JOBDIR=jobdir/spider-1). The only resolution i've found was here:

but i haven't understand the idea.
So is it possible to pause/continue job with Scrapyd?
Thanks for your time
