My understanding is that the limit is as you described so a 5002 entry list property will require 5002 entries in the index. If you have multiple list properties then the number of index entries may be a cross product if the index contains more than one list property (try to avoid this).
I am guessing the reason the dev server is letting you have 5002 entries is that the dev server does not actually enforce the limits of the production server in many cases (especially with regard to indexes). One to watch out for is exploding indexes where the dev server will automatically create the index definitions for you and continue to operate fine even if you have a query requiring an exploded index (because the dev server does not use those indexes) but once you upload to the production server your index will probably fail to be created. Side note: Does anyone know of a list that details the known differences between the dev server and the production server? - Bryce On May 9, 1:56 am, lp <[email protected]> wrote: > hi guys > i am attempting to understand the limits below. > > seehttp://code.google.com/appengine/docs/java/datastore/overview.html > > Limit > > maximum entity size 1 megabyte maximum number of values in all indexes > for an entity (1) 5,000 values > > 1.
