El Martes día 18 de Septiembre 2012 Google App Engine publicó una nueva release de su SDK.
Es impresionante el paso adelante que han dado con su nueva librería NDB de acceso al nuevo Datastore HRD (por si quieres aprender más sobre NDB Google App Engine), la cual llevo utilizando desde hace ya tiempo, como han cambiado la filosofía de trabajo y como yo mismo he tenido que cambiarla también.
Todo lo que hacías de manera síncrona lo puedes hacer también de manera asíncrona, solo tienes que cambiar tu forma de pensar. Y, generalmente, la manera más sencilla suele ser la mejor solución.
Además, la introducción del nuevo Text Search (Google App Engine Search api), que permite realizar full searchs en su datastore me está ayudando mucho en el desarrollo de nuevas funciones para interfaces de usuario. También ayuda mucho a simplificar la manera en la que tenía que simular esta función de búsqueda hasta ahora.
Es algo bastente nuevo y que está todavía en fase experimental, pero es una de los requisitos más pedidos al grupo de Desarrollo de App Engine y no creo que desaparezca así como así.
No puedo comentar mucho sobre el tema, porque todavía estoy con pruebas y tests, pero el resultado está siendo impresionante.
Dejo publicadas las notas de la nueva release.

A note about an upcoming change: starting with the 1.7.3 release of App Engine, data statistics will report statistics on property type usage by indexes using the documented property type names (“Integer”, “Key”, etc, see https://developers.google.com/appengine/docs/python/datastore/stats) rather than the current property representation names (“INT64”, “REFERENCE”, etc, see http://goo.gl/db5dT). This will affect the Stat_PropertyType, Stat_PropertyType_Kind, Stat_PropertyType_PropertyName_Kind and their per-namespace equivalents. This will also affect the displayed “Breakdown by Property Type” under the “Datastore Statistics” in your application’s console.
