title: Google App Engine Channel API quota
body: <p>I know that there are similar questions, but they aren't up to date anymore. I'd like to know how much it costs to create 1 / 10 / 100 / 1000 channels per day? I only find the <a href="https://developers.google.com/appengine/pricing" rel="nofollow">pricing list</a>, which doesn't mention channels, and the <a href="https://developers.google.com/appengine/docs/quotas#Channel" rel="nofollow">quota list</a>, which only says "depends on your budget".</p>
  
  <p>I run out of quota really fast. If users access your website only for a short time, then creating 100 channels isn't enough (all other quotas are still 0%). I also read, that reusing channels isn't possible.</p>
  
  <p>Channels are available for two hours. After that they are released. Does the quota mean: "You are only allowed to create 100 channel per day" or does it mean: "You are only allowed to have 100 channels at the same time"? </p>
  
  <p>There is also an API do define when a channel should be released. Does this API even make sense? Let's say I choose to release the channel after one minutes. So while using browsing my website for 5 minutes, the user would create 5 different channels. Does it make sense to decrease the release time?</p>
  
  <p>Thanks!</p>
