"Supporting OLTP and OLAP Queries on Cloud Platforms"

 

Abstract:
 

MapReduce-based systems have been widely used for large-scale data analysis. Although these systems achieve storage-system independence, high scalability, and fine-grained fault tolerance, their performance have been shown to be unsatisfactory.It has also been shown that MapReduce-based systems are significantly slower than Parallel Database systems in performing a variety of analytic tasks. Some attribute the performance gap between MapReduce-based and Parallel Database systems to architectural design. This speculation yields an interesting question: Must a system sacrifice performance to achieve flexibility and scalability?  Consequently, we conducted an in-depth performance study of MapReduce in its open source implementation, Hadoop. We identified various factors that have significant performance effect on the system. Subsequently, based on what we have learned,  we propose a new architectural design as an attempt to support both OLTP and OLAP queries on Cloud platforms. I shall describe some of our ongoing work in this talk.
