According to https://developers.google.com/appengine/docs/python/datastore/indexes#Unindexed_Properties, "You declare a property unindexed by setting indexed=False in the property constructor".
One incurs the cost of a write (or 2?) for every property of a record that gets written; so, for a table with about 25 fields (once you include all of the ones web2py adds), inserting 300 records incurs the cost of 14K+ writes; as the free account has a limit of 50K writes per day, that is rather limiting. It is easy to turn such indicies back on, but you have to re-write every record in order to repopulate them. - Scott On Thursday, February 21, 2013 4:51:59 PM UTC-5, howesc wrote: > > i'm being lazy here....do you have the instructions (or link to > instructions) from GAE for disabling indexes? i don't have it handy right > now.... > > we can check if the DAL has a secret way to handle it, and/or create a > patch to allow it. > > may i ask what advantage you are hoping to achieve by skipping those > indexes? i've left them on for fear of making a bad choice that i can't > revert. > > christian > > On Thursday, February 21, 2013 5:56:07 AM UTC-8, Scott Hunter wrote: >> >> As I understand it, the GAE datastore will automatically create an index >> for every field of every table (to facilitate queries using single fields); >> those requiring multiple fields also get generated, but will get added to >> index.yaml by the SDK when tested locally.
