在「Amazon CloudFront Makes it Easier to Invalidate Multiple Objects」這邊看到的消息，Amazon CloudFront 總算是支援 Wildcard Invalidation 了。價錢與 Single Object Invalidation 相同，都是每次 USD$0.005。
依照 Invalidating Objects (Web Distributions Only) 這邊的說明，Wildcard 的部份只能用在結尾：
To invalidate objects, you can specify either the path for individual objects or a path that ends with the * wildcard, which might apply to one object or to many, as shown in the following examples:
不過還是有些限制，包括了 Single Object Invalidation 的同時最多 3000 條的限制：
If you're invalidating objects individually, you can have invalidation requests for up to 3,000 objects per distribution in progress at one time. This can be one invalidation request for up to 3,000 objects, up to 3,000 requests for one object each, or any other combination that doesn't exceed 3,000 objects. For example, you can submit 30 invalidation requests that invalidate 100 objects each. As long as all 30 invalidation requests are still in progress, you can't submit any more invalidation requests. If you exceed the limit, CloudFront returns an error message.
以及 Wildcard Invalidation 的同時 15 條限制：
If you're using the * wildcard, you can have requests for up to 15 invalidation paths in progress at one time.
而且每次 invalidate 可能都要 10～15 分鐘：
It usually takes 10 to 15 minutes for CloudFront to complete your invalidation request, depending on the number of invalidation paths that you included in the request.
