[google-appengine] How to insert a json object in a datastore?

Hi, I am trying to insert a key value pair map in a datastore as one of the columns of a model. I found some implementations of a custom datastore data type for a dictionary. I was wondering if JSON object could be inserted instead of having a custom datatype. I tried json dumps to insert a json ob

No, IDs are not guaranteed contiguous. In my sample application, my IDs routinely jump from 1, 2, 3, 1000 for a lot of my kinds, so you can't count on continuity. I generally like the custom ID solution based on a sharded counter. This should guarantee continuity if you use a transaction... see htt

The best way is to assign a one-up counter to each record as you create it, then call random.randint(1,max_counter) to determine the desired record. To retrieve multiple random entities in a query, do a filter('IN ', [my random nums]). Note that behind the scenes this generates multiple queries,
