Google I/O playlist, day 8: Next gen queries

This is the eighth in a series of posts providing a day-by-day playlist to help break up the Google I/O session videos - specifically the App Engine ones - into manageable chunks for those that haven't seen them. Don't worry, we're nearly done!

First up, apologies for the lack of posts the last few days. I spent the weekend at Hack Camp, so Friday was spent preparing for it, and Monday and Tuesday were spent recovering and catching up!

Today's session is Alfred Fuller's session, Next Gen Queries. If you're interested in the continued evolution of the datastore API, this is a must-watch talk. It's completely language-agnostic, too. If you're looking for better background knowledge, Brett's talk from I/O '09 is well worth watching first, though.

Alfred goes into a lot of detail about some of the exciting improvements you can expect in future iterations of the Datastore API, largely due to his work on extending and improving the ZigZag merge join strategy in App Engine, as well as better support for MultiQuery. As an extra bonus, check out 31:29 for details of an improvement you can take advantage of today!

Alfred also talks extensively about doing spatial and other multi-dimensional indexing using Hilbert Curves, something I've written about before.
