Will it lose data potentially?

Hi,

I'm using em-twitter to track the /1.1/statuses/filter.json api.

An example code that includes a periodic timer would like below :

EM.run do
    client = EM::Twitter::Client.connect(options)
    client.each do |status|
        # handle_tweet ...
    end
    EM.add_periodic_timer(5) do
        # other job
    end
end

So the question is, since every 5 seconds event loop will jump to other job (e.g. an async connection to database), will this potentially lose some streaming data we are tracking at this point of time?

Thanks

I would advise not blocking the event loop inside your timer. But theoretically, no, I don't think this would prevent data from being received. I believe your data would be handled in the next tick.
