That's 50k reads every 5 minutes if applied to dnkoutso's use case, which could hurt a bit.
The alternative I've mentioned may be cheaper if the number of items tracked is very large compared to the frequency of the count increments. I believe my method incurs 6 write ops per increment (1 + 2 to index the referenced entity, multiply by 2 since the increment will be deleted when flushed), but each flush will only update the entities that have their counts changed. If live count is not necessary, then the write ops can be reduced to 2 as the referenced entity does not have to be indexed. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
