Hello. I have to implement the following use case.
I have some external upstreams that are not under my control and do not have failover. I need to have a sort of "permament cache" of all these upstreams; in case of failure of one external upstream, apisix has to load from this permament cache, regardless of the age of the cache. I'm trying to figure how to implement this pattern. Apisix has the proxy-mirror plugin and health checks on upstreams that can help, but I do not know how to implement the service that stores the mirrored traffic and replays to api requests. Any suggest? Is this a good way? Regards Alberto
