Recent Projects


 

Raft consensus protocol based distributed key-value store. Designed as a final project for CMSC 23310 (Distributed Systems), nodes use RabbitMQ to communicate with each other and mapDB as a persistance layer. Such a system is partition-tolerant and consistent and can always make progress as long as a majority of nodes are active.
