NewSQL [Valduriez & Jimenez-Peris 2019] is the latest technology in the big data management landscape, enjoying a fast-growing rate in the DBMS and BI markets. NewSQL combines the scalability and availability of NoSQL with the consistency and usability of SQL. By blending capabilities only available in different kinds of database systems such as fast data ingestion and SQL queries and by providing online analytics over operational data, NewSQL opens up new opportunities in many application domains where real-time decision is critical. Important use cases are eAdvertisement (such as Google Adwords), IoT, performance monitoring, proximity marketing, risk monitoring, real-time pricing, real-time fraud detection, etc. NewSQL may also simplify data management, by removing the traditional separation between NoSQL and SQL (ingest data fast, query it with SQL), as well as between operational database and data warehouse / data lake (no more ETLs!). However, a hard problem is scaling out transactions in mixed operational and analytical (HTAP) workloads over big data, possibly coming from different data stores (HDFS, SQL, NoSQL). Today, only a few NewSQL systems have solved this problem. In this talk, I introduce the solution for scalable transaction and polystore data management in LeanXcale, a recent NewSQL DBMS.

Short Bio

Patrick Valduriez is a senior scientist at Inria, France, and the scientific advisor of the LeanXcale company. He has also been a professor of computer science at University Pierre et Marie Curie (UPMC), now Sorbonne University, in Paris(2000-2002) and a researcher at Microelectronics and Computer Technology Austin, Texas (1985-1989). He iscurrently the head of the Zenith team that focuses on data science, in particular, scientific data management. He has authored and co-authored many technical papers and several textbooks, among which “Principles of Distributed Database Systems” (with Professor Tamer Ozsu,University of Waterloo). He has served as PC chair of major conferences such as SIGMOD and VLDB. He was the general chair of SIGMOD04, EDBT08 and VLDB09. He received prestigious awards and prizes. He obtained several best paper awards, including VLDB00. He was the recipient of the 1993 IBM scientific prize in Computer Science in France and the 2014Innovation Award from the French Academy of Science. He is an ACM Fellow.
