The Select operation returns a set of Attributes for ItemNames that match the select expression. Select is similar to the standard SQL SELECT statement. The total size of the response cannot exceed 1 MB in total size. Amazon SimpleDB automatically adjusts the number of items returned per page to enforce this limit. For example, even if you ask to retrieve 2500 items, but each individual item is 10 kB in size, the system returns 100 items and an appropriate next token so you can get the next page of results. Operations that run longer than 5 seconds return a time-out error response or a partial or empty result set. Partial and empty result sets contains a next token which allow you to continue the operation from where it left off. Responses larger than one megabyte return a partial result set. Your application should not excessively retry queries that return RequestTimeout errors. If you receive too many RequestTimeout errors, reduce the complexity of your query expression. When designing your application, keep in mind that Amazon SimpleDB does not guarantee how attributes are ordered in the returned response.
