Indexed DB/WebStorage in GWT?
Howdy, all, Is anyone using webstorage or indexedDB client side data storage with GWT? Pointers to projects appreciated... Aside: I note that the WebStorage group reached an impasse and stopped supporting the spec last fall. I note further that http://www.w3.org/TR/IndexedDB/ seems to be alive and kicking, but a brief reading seemed to indicate that this is a great system for key-object mappings, but not so great for the generic sql case of select rows from foo where name is blah group by this order by that kind of queries. ( might be wrong - section 3.1.3 keys can be DOMStrings. Since can supply a keyrange to an index, you may be able to generate the kind of selects I am used to, as long as you can generate an index such that the result of that query would be expressable as either indexkey==foo or low indexkey hig. Aside aside, does anyone have real world experience? I do not mind if the results only work on Chrome/FF/Safari, but IE would also be cool.

Re: Indexed DB/WebStorage in GWT?
As Jeff points out, Storage is supported in GWT today. Storage is the HTML5 key/value pair datastore and has a 5mb limit (unless you are installed via the Chrome Web Store). John LaBanca has a good overview (that is pretty entertaining) here: http://www.youtube.com/watch?v=KEkR1ox_K10 We don't currently have an IndexedDb wrapper. IndexedDb (http:// www.w3.org/TR/IndexedDB/) is a successor to the defunct WebSQL and is a much more powerful datastore than Storage, supporting queries and such. GWT support for IndexedDb will require some serious work and I don't know of anyone looking into it at the moment.
