Hi James. I don't have any specific information for you, but if you don't get any other responses, you may build a small test system to see how it performs, and I'm interested in hearing your results. In the meantime, all relevant task queue limits are linked to below:
http://code.google.com/appengine/docs/java/taskqueue/overview.html#Quotas_and_Limits Of interest, you can have up to 10 active queues (plus the default queue) with a total task invocation rate of 10 tasks per second across all queues. - Jason On Wed, Oct 28, 2009 at 8:36 AM, James Cooper <[email protected]>wrote: > > Hi there, > > I asked a similar question a couple of days ago, but I'll try > different wording and see if it generates any interest. > > Has anyone successfully simulated MapReduce using task queues?
