Hi there, 3 styles answers to the question :-) *Short version:* Don't do it. Blocking the default dispatcher is a very very very bad thing, do it on a dedicated dispatcher.
*Documentation version: * First, this is very well documented here: http://doc.akka.io/docs/akka-http/current/scala/http/handling-blocking-operations-in-akka-http-routes.html Please read the above documentation, it explains what happens to the dispatchers and how one should manage blocking there. In addition to the link Rafał shared you can also read: http://doc.akka.io/docs/akka/current/general/actor-systems.html#Blocking_Needs_Careful_Management *Visual version:* And the stars of heaven fell to the earth, even as a fig tree casts her untimely figs, when she is shaken of a mighty wind. And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places. [...] For the great day of his wrath is come; and who shall be able to stand?
