Abstract
In this talk I will discuss the design of a new Geo-distributed key-value datastore, named ChainReaction, that offers causal+ consistency, with high performance, fault-tolerance, and scalability. ChainReaction enforces causal+ consistency, which is stronger than eventual consistency, by leveraging a new variant of chain replication which I will also address in the talk. Experimental results obtained using the Yahoo! Cloud Serving Benchmark show that ChainReaction has better performance in read intensive workloads while offering competitive performance for other workloads compared with relevant competing solutions while requiring less metadata when compared with previous work.
