Dispatcher (executor) is mostly important if you're doing bad things on it - like blocking on responses for example. If you're handling things in async / reactive ways the default akka dispatcher is fine most of the time, just don't block on it (read this: http://doc.akka.io/docs/akka-http/10.0.5/scala/http/handling-blocking-operations-in-akka-http-routes.html same thing applies in any code really).
It is more interesting to think about the connection pools configured than the dispatcher here. Those can limit how many connections you can have open to a given host, what timeouts should be set for idle timeouts and cleaning up connections etc. You can read about this in documentation on pools in akka http. -- Konrad `ktoso` Malawski Akka <http://akka.io> @ Lightbend <http://lightbend.com> On 26 April 2017 at 09:15:00, Albert Gorski (albgor...@gmail.com) wrote: Hi, I've Akka HTTP service which calls 5 other services using Akka HTTP client (Host-Level Client-Side API). Currently I have executor context per service (host/port). What is the best practice for setting executor context? I mean, should I use fork-join or cached or fixed thread pool or maybe something else? Is it good to configure executor context pro service? It's a kind of bulkhead solution, but is it really good for performance? Thank you for response in advance:) Cheers, Albert -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
