Summary: Phi accrual failure detector
Key: RATIS-428
URL: https://issues.apache.org/jira/browse/RATIS-428
Project: Ratis
Issue Type: Improvement
Reporter: Vladimir Rodionov
Assignee: Vladimir Rodionov
Failure detectors are an important piece in designing robust distributed
systems. Components must be expected to fail, and the rest of the system should
either continue functioning properly (ideal) or at the very least degrade
gracefully instead of crashing or becoming corrupted. Because of the unreliable
nature of communication over networks, however, detecting that a node has
failed is a nontrivial task. The *phi accrual failure detector* is a popular
choice for solving this problem, as it provides a good balance of flexibility
and adaptability to different network conditions. It is used successfully in
several real-world distributed systems, such as Apache Cassandra (see here) and
Akka clusters (see here), and also has a Node.js implementation.
