@leventov , @gianm , I believe request caching https://github.com/Netflix/Hystrix/wiki/How-it-Works#RequestCaching can be helpful in solving this.
On a different note, we should consider using Hystrix library which helps control interactions between distributed services by adding latency tolerance and fault tolerance logic improving overall system resiliency. https://github.com/Netflix/Hystrix/wiki
Hystrix provides a number of patterns to improve system resiliency - Sync/Async executions, Command groups/thread pools, Request collapsing/caching etc etc.
