Amazon adds sort feature to SimpleDB »

Amazon AWS SimpleDB now supports sortable query result sets. Previously query results came back in insertion order only, but now you can sort on (only) one attribute. This makes a lot of standard relational DB use-cases more feasible for implementation in SimpleDB, as it makes for less data post-processing.

Sorting on only one attribute is still quite limiting, though, and queries still only return object IDs, which forces many further queries to retrieve the full data-set.
