Tour of Akka Cluster – Akka Distributed Data

Building distributed systems is hard. Pesky things like the laws of physics get in the way of maintaining state accross geographically (and chronologically) disparate systems, and, if that weren’t already outrageous enough in itself, those systems may be subject to network failures, forcing us to think about annoying tradeoffs regarding consistency, availability and the meaning of life. One of the … Read More

A new adaptive accrual failure detector for Akka

Akka uses the The Φ Accrual Failure Detector for failure detection, which is to say for answering the question of whether a node is alive or not. That’s one of the harder problems of distributed systems since it is virtually impossible (from the point of view of one node) to tell the difference of a remote system being completely unavailable … Read More
