Hystrix vs seneca: What are the differences?

What is Hystrix? Latency and fault tolerance library. Hystrix is a latency and fault tolerance library designed to isolate points of access to remote systems, services and 3rd party libraries, stop cascading failure and enable resilience in complex distributed systems where failure is inevitable.

What is seneca? A Micro-Services toolkit for Node.js. Seneca is a toolkit for organizing the business logic of your app. You can break down your app into "stuff that happens", rather than focusing on data models or managing dependencies.

Hystrix and seneca are primarily classified as "Fault Tolerance" and "Microservices" tools respectively.

Some of the features offered by Hystrix are:

• Latency and Fault Tolerance
• Realtime Operations
• Concurrency

On the other hand, seneca provides the following key features:

• pattern matching: a wonderfully flexible way to handle business requirements
• transport independence: how messages get to the right server is not something you should have to worry about
• maturity: 5 years in production (before we called it micro-services), but was once taken out by lightning

Hystrix and seneca are both open source tools. It seems that Hystrix with 17.7K GitHub stars and 3.63K forks on GitHub has more adoption than seneca with 3 GitHub stars and 1 GitHub forks.
