            https://docs.scrapy.org/en/latest/topics/practices.html#run-scrapy-from-a-script

            There’s another Scrapy utility that provides more control over the crawling process: scrapy.crawler.CrawlerRunner. This class is a thin wrapper that encapsulates some simple helpers to run multiple crawlers, but it won’t start or interfere with existing reactors in any way.
            It’s recommended you use CrawlerRunner instead of CrawlerProcess if your application is already using Twisted and you want to run Scrapy in the same reactor.

            https://docs.scrapy.org/en/latest/topics/practices.html#running-multiple-spiders-in-the-same-process

            By default, Scrapy runs a single spider per process when you run scrapy crawl. However, Scrapy supports running multiple spiders per process using the internal API.

            apscheduler and apscheduler-django don't directly support that.

            You can implement and use a custom executor that tracks the process running a job and kills the process if trying to submit a job that is currently running.

            Here's a MaxInstancesCancelEarliestProcessPoolExecutor that uses pebble.ProcessPool.

            Dask distributed has a fire_and_forget method which is an alternative to e.g. client.compute or dask.distributed.wait if you want the scheduler to hang on to the tasks even if the futures have fallen out of scope on the python process which submitted them.

            ANSWER

            Answered 2022-Feb-24 at 07:51

            TBF, I'm not familiar with Google Cloud Run, but if I understand correctly the point is that you code will only be invoked when a request is made to the app, i.e. it's one of those "serverless" setups - is that correct?

            If so: What updater.start_polling() does is start a long running background thread that fetches updates continuously. To have your bot responsive 24/7 with this method, your script needs to run 24/7. Now the point of serverless setups is that your code only runs on demand, so for this hosting method a more reasonable approach would be to only invoke your code when your bot receives an update. This can achieved using a webhook instead of long polling. There is a section on this in the PTB wiki. See also this thread about AWS Lambda, which is similar AFAIK.

            However one should note that stateful logic like ConversationHandler is hard to realize in such setups: By default ConversationHandler keeps track of the current state in memory, so the information is lost on shutdown of the process. You can use persistence to store the data, but I'm not sure how well this works with serverless setups - there might be race conditions if multiple updates come in at the same time. So another idea would be to switch to a different hosting service that allows to run your process 24/7.
