Great talk. Hope there will be an article. I wonder whether i understand the motivation for sequence numbers? We cannot simply timestamp worker entities and then processes them chronologically, because times on instances may vary greatly? If that's the case, how can we trust the eta parameter when creating tasks?
Is it reasonable to use this technique for maintaining lossless counters, or was this just an easy to discuss example (i really do need lossless counters)? Lastly, is the risk of the worker/task race condition greater than the risk of the memcache lock disappearing? Do i have to design around the possibility of this lock disappearing? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
