Fast purge only works on certain kind of objects in certain kind of configurations, not to mention the idea of "I would like tom make 20k purge requests in a second via an API" is met with stares.
Interesting. I only have experience with the occasional simple (manual) purge and I could verify the object was invalidated quickly. Can you elaborate on an example config where this goes awry?
Fast purge works with all kinds of site delivery ( and site delivery based ) products. Unlike modern CDNs Akamai other products ( such as for example VOD and media services ) do not live in the same object space and hence are not fast purge compatible.
You would think purging a video stream would be the same as purging a standard site delivery object, after all it the stream is http(s) accessible .m3u8 and a pile of .ts chunks but that's not the case -- in some cases it can take up to one hundred and twenty minutes.
