This talk is part of the System Research Seminar series

 

Abstract: Exisiting big data systems, such as MapReduce and Spark, are designed for programmability, scalability and fault tolerance at the price of absolute performance. We discuss the fault tolerance and performance and conclude that they are not mutually exclusive. We give a high performance distributed graph processing system, as an example of a big data system designed for performance. It only requires 10% memory required by GraphX and is 50X faster than GraphX for typical graph processing workloads.
