Wow! you guys are so fast that this thread looks like a chat :) In the past, quota limits were based on 2 conflicting objectives:
- discouraging people from building non-scalable applications by restricting APIs & time limits. - discouraging people from using app engine at an "unfair" cost during the request pricing regime. The synthetic limits problem that you mentioned are the result of the request pricing regime. It was frustrating to work-around the pricing constraints instead of constraints based on the best practices for scaling. With the new instance based pricing, these quota limits exist only as a best practice for scaling, IMO. For example, urlfetch deadline limit is now configurable. Similarly, Stanford NLP works quite well on the java version or you could very well use Alchemy API, depending on how much control you want to have on your language heuristics. It is sad that you are leaving. But, I guess, it is a collateral damage of being an early adopter of a technology whose business model & technology were figured out in the process. regards, mani On Friday, 23 November 2012 09:28:18 UTC+5:30, Brandon Wirtz wrote: > > >IMO, backends & quota limits are mostly problems arising out of bigtable > data migration (for new application >versions) & joins/aggregates (in > reporting). > > > > A few “for instances” > > We get feeds from Associated Press.
