Google App Engine 1.6 预览版发布,增加了对Python 2.7,Premier Accounts和Backends的支持,以及一些其他的改进。

产品变化:

  • Min Idle Instances: You can now adjust the minimum number of Idle Instances for your application, from 1 to 100. Users who had previously signed up for “Always On” can now set the number of idle instances for their applications using this setting.
  • Max Pending Latency: For applications that care about user facing latency, this slider  allows you to set a limit to the amount of time a request spends in the pending queue before starting up a new instance.
  • Blobstore API: You can now use the Blobstore API without signing up for billing.

数据存储变化:

  • High Replication Datastore Migration Tool: We are releasing an experimental tool that allows you to easily migrate your data from Master/Slave to High Replication Datastore, and seamlessly switch your application’s serving to the new HRD application.
  • Query Planning Improvements: We’ve published an article that details recent improvements to our query planner that eliminate the need for exploding indexes.

Python

  • MapReduce: We are releasing the full MapReduce framework in experimental for Python. The framework includes the Map, Shuffle, and Reduce phases.
  • Python 2.7 in the SDK: The SDK now supports the Python 2.7 runtime, so you can test out your changes before uploading them to production.

Java™

  • Memcache API Improvements: The Memcache API for Java now supports asynchronous calls. Additionally, putIfUntouched() and getIdentifiable() now support batch operations.
  • Capability Testing: We’ve added the ability to simulate the capability state of local API implementations to test your application’s behavior if a service is unavailable.
  • Datastore Callbacks: You can now specify actions to perform before or after a put() or delete() call.

目前Google官方公布的数据,Google App Engine 每月1k亿次点击,30万+活跃应用,10万开发者。
