from experience, you have to be careful not to over-think the API for example, those extra query operations may benefit particular implementations (like SQL) but you might find that in reality they only represent a few percent of supplied/used implementations. in fact with disruptive technology like Qi4j you might find people are less worried about performance of legacy systems and more interested in how easy it is to plug in their new indexing system. if the query API has a lot of operations, it will take longer to write new implementations (example: consider the difference between implementing Iterable and implementing Collection) so imho, get it out for people to try and feedback - I've never seen an API that was right the first time round ;) Alin > _______________________________________________ > qi4j-dev mailing list > [email protected] > http://lists.ops4j.org/mailman/listinfo/qi4j-dev > -- Cheers, Stuart
