[google-appengine] Since Monday, these simple SQL operations translate to expensive DataStore operations, why?
I noticed that a number of simple SQL operations that my application is dependent on generate very high quota usage. Basically, one run of the three operations listed below are enough to use up my daily free quota!! Running appstats, I see a lot of datastore_v3.Next calls for the first two calls. I assume I am doing something very wrong but I am not sure how to fix it. Could anyone please give me some pointers on how to address this? thank you PS. an interesting twist is that the below code worked just fine under the old payment model. - // The table Something below has around 50k rows.

PersistenceManager pm = ... // Select COUNT(*) from Something Query q = pm.newQuery(Something.Class, null); q.setResult(count(this)); q.execute(); // select COUNT(*) from Something where 1234 feild Query q = pm.newQuery(Something.Class, this.field field); q.declareParameters(Long field); q.setResult(count(this)); q.executeWithArray(1234); // select * from Something order total DESC Query q = pm.newQuery(Something.Class, null); q.setOrdering(total DESC); q.execute(); -- You received this message because you are subscribed to the Google Groups Google App Engine group.
