About

Currently I'm a Query Engine Technical Director  at LeanXcale  and associate researcher at HASLab, one of the INESC TEC research units. I obtained a degree in Computer Science and Systems Engineering from University do Minho in 2005 and the Ph.D in the MAP-i Doctoral Programme in Computer Science in 2012. I have a strong background in distributed systems and large scale data management and more than 10 years of experience in national and international research projects in distributed systems: Big Data, Large scale query processing, Cloud computing, NoSQL and SQL databases,  and database replication.
Currently, I'm working in FP7 European research projects LeanBigData and CloudDBAppliance. I had co-supervise several research grant holders and master thesis. I had published research papers on large scale and dependable distributed systems and has served as reviewer for several highly reputed conferences and workshops such as SRDS, Middleware, LADC, DAIS and MW4SOC. He serve as PC of the MW4NG workshop and DADS conference. I also created and served as chair of the WPSDS workshop.

Abstract
The ability of NoSQL systems to scale better than traditional relational databases motivates a large set of applications to migrate their data to NoSQL systems, even without aiming to exploit the provided schema exibility. However, accessing structured data is costly due to such exibility, incurring in a lot of bandwidth and processing unit usage. In this paper, we analyse this cost in Apache HBase and propose a new scan operation, named Prepared Scan, that optimizes the access to data structured in a regular manner by taking advantage of a well-known schema by application. Using an industry standard benchmark, we show that Prepared Scan improves throughput up to 29% and decreases network bandwidth consumption up to 20%. © 2017 ACM.
