Technologies for Testing Distributed Systems, Part I - Rest for the Wicked
Last month, Crista Lopes asked the twitter verse: Twitter friends: what papers or frameworks do you recommend regarding distributed systems regression or integration testing techniques? â€” Crista Lopes (@cristalopes) January 22, 2016 She compiled the answers she received in a blog post, which ended on a dispirited note: In spite of unit testing being a standard practice everywhere, things donâ€™t seem

Effective actors japanesesub
This document provides an overview of effective actor modeling techniques. It discusses actors as isolated, concurrent processes that communicate through asynchronous message passing. It provides examples of how to model domains and worker supervision hierarchies using Akka actors and routers. It also discusses techniques for introducing parallelism by creating multiple actor instances and distrib

Don't use Actors for concurrency
Don't use actors for concurrency. Instead, use actors for state and use futures for concurrency. A common practice I've seen in scala code is to use actors for concurrency.

I assert that this is a bad practice and should be considered an antipattern most of the time it is used. Actors s

Links: Akka Home Akka Docs This is another topic which comes up from time to time on the mailing list: typed actors are â€œniceâ€, but some things work differently or not at all, so what exactly are they good for?
