报告内容摘要：   

This paper is aboout progress indicators(PIs) for SQL queries. Firstly, it discuss the MSRPI and the WiscPI(both of them are PIs) and studies their performance. Secondly, it introduces a new cost-based progress indicator, called GSLPI,which produces more accurate progress estimates than before. Thirdly, it discusses how to refine cardinality and cost estimates by using runtime information.

报告内容摘要：   

Very large data processing is increasingly becoming a necessity for modern applications. For state of the art parallel data processing systems, systematic monitoring and prediction of progress is a problem. This paper discuss the need for new type of progress indicators - the so called "progress indicators on steroids" for big data system to improve upon current progress indicators technology in every aspect.
