Believe it or not, Ikai could do version of the "Dummies" books for GAE with his helpful doodles and have a good alternative to life at to Google-Plex.
The "high transaction rate, monotonically increasing" field that supports queries without having to dedicate an index is something that if Google could accomplish would be even cooler than Task Queues -- and I love me some TQs. Sure its hard, but if there is ONE issue that has been consistently discussed without a good solution over my years viewing GAE discussion threads, this IS IT. It would be awesome if G. could devise a Big Table solution. As ever, fingers crossed. -stevep On May 8, 8:05 am, Michael Hermus <michael.her...@gmail.com> wrote: > > I searched through Google I/O 2011 sessions, and I found this one: > > http://www.google.com/events/io/2011/sessions/scaling-app-engine-appl... > A good article on the topic (many people are probably already familiar with > this > post):http://ikaisays.com/2011/01/25/app-engine-datastore-tip-monotonically... > > Both confirm that this is definitely an issue, and provide some ideas on > how to avoid the situation.
