Jepseni

Jepseni, also known as Jepsen, is a software tool used for testing the correctness of distributed systems. It was developed by Kyle Kingsbury and is widely used in the industry to ensure that distributed databases and other distributed systems behave correctly under various failure scenarios. Jepsen is particularly known for its ability to simulate network partitions, node failures, and other types of faults to see how a system responds. This helps in identifying potential issues such as data inconsistencies, deadlocks, and other correctness problems. The tool is designed to be easy to use, with a focus on generating comprehensive and reproducible test reports. Jepsen supports a variety of distributed systems, including databases like Cassandra, Riak, and Redis, as well as messaging systems and other distributed applications. By running Jepsen tests, developers and operators can gain confidence in the reliability and correctness of their distributed systems, making it an essential tool in the field of distributed computing.
