. Hystrix has thread and signal isolation with fallback mechanism and circuit breaker functionality, request caching and request packaging (requests collapsing, i.e., automatic batching, translator note), and monitoring and configuration functions. Hystrix is based on the Flex engineering work launched by the Netflix API team in 2011, which currently handles tens of billions of of isolated threads and hundreds of millions of of isolated signal calls per day in Netflix. Hystrix is an open source

Linux under the multi-process management tools for development and operations are very useful, common features of the main mainstream tools are Monit, supervisor. However, it is recommended to use the lightweight gadget goreman in development. Goreman is a rewrite of the widely used foreman under Ruby, after all, Golang-based tools are much easier to use. Incidentally: Goreman's author is Mattn, a Japanese programm
