Hi, Even though you only have one composite index on __key__ (desc), there are also other indexes you may have. For example, every __key__ has an ascending index and every property that you have indexed (which may have been done automatically for you unless you specified otherwise for example if you're using JDO) will have 2 (yes 2) indexes created (one ascending and one descending). What's more if those entries are lists then they will have 1 index entry for each item in the list. So, ten items in an indexed list field will have 20 index entries (10 for the ascending index and 10 for the descending index). Also, remember that the data in the field is copied into the index entry so if you have indexes on long text fields then you've got problems. Also, if you are doing a lot of updates/deletes then you can run out of storage space because AppEngine does soft deletes where it marks items as deleted and then periodically cleans them up. I myself see that it takes about 24 hours for storage to be reclaimed and reported in the dashboard but there has never been any official word that I know of on how often this happens. Hope this helps, Stephen
