什么是Google App Engine数据存储大小限制/如何扩展？

What is Google App Engine datastore size limit / how it is scalable?

我读到的信息数据存储的速度有多快，API的限制是什么，但没有找到相关信息大的可能是数据存储。

I was read information how fast is datastore and what is API limitation but not find informaition how large could be datastore.

推荐答案

没有限制你永远不会达到（除了你的口袋里）。

There is no limit you will ever reach (except thats of your pocket).

从google.appengine.ext.ndb key.py：Integer ID必须至少为1且小于2 ** 63。
这些是您在插入对象时自动分配的值。

From google.appengine.ext.ndb key.py: Integer ids must be at least 1 and less than 2**63. These are the one you'll get automatically assigned when inserting an object.

但是，这并不限制您使用自定义插入更多对象的能力（字符串）键。
它的编码形式（base64）可以长达500个字节，这比128位地址空间多，这比你填充的空间要大。 （请参阅 https://blogs.oracle.com/bonwick/entry/128_bit_storage_are_you ）

However, this does not limit your ability to insert more objects using custom (string) keys. Its encoded form (base64) can be up to 500 bytes long, which is more than a 128 Bit Address-space, which is more than you could ever fill.
