Is it possible to search through Item IDs in Amazon SDB, something like:

SELECT * FROM myDomain WHERE ItemName like '1234%'

I’m new to nosql, making first app with Amazon SimpleDB, figuring out best schema for my data.

Was thinking of making ItemName a concatenation of userId, topicId and, say, a timestamp – for a forum, for instance. So that getting all posts of a single user would be by searching through ItemNames, which are, I suppose, indexed – perhaps, a faster search.

Or should I just assign unique IDs to my items and never bother with their sorting, naming convention etc. – doing search only through Attributes?

    Yes.. you search through Item IDs in Amazon SimpleDB and you can even sort your data using item IDs too. Here are some examples of query – 

    select * from domain where itemName() like '1234%'
select * from domain limit N
select * from domain where itemName() like '1234%' order by itemName() limit 2500.

    For more details you refer following documentation –
