Yes. You're probably wondering how we manage the older versions of an object (aka id + version) in the DocService. We'd probably delete the object as it's deleted from the index? I use the word "object" to denote something different than a document which can be short lived. An object exists over multiple updates. We can start with the interface, and implement a default implementation using Apache licensed Voldemort http://project-voldemort.com ? 2009/8/11 Noble Paul നോബിള് नोब्ळ् <noble.p...@corp.aol.com>: >> This is why we'd want to use optimistic concurrency, meaning >> versions of ids encoded in the documents (which would also be >> stored in the index ala GData). > > So ,when the stored fields are fetched from the "DocumentService" the > version number also is sent? > > As Grant mentioned , it would be nice to have the interface ready and > make it possible to have multiple implementations > > -- > ----------------------------------------------------- > Noble Paul | Principal Engineer| AOL | http://aol.com >
