NewSQL Through the Looking Glass

Abstract

Several applications require to handle large and heterogeneous data volumes as well as thousands of OLTP transactions per second. Traditional relational databases are not suitable for these requirements. On the other hand, NoSQL databases are able to deal with Big Data, but lacks the support to the traditional ACID properties. NewSQL is a new class of databases that combines the support to OLTP transactions of relational databases with the high availability and scalability of NoSQL databases. However, few works in the literature explore the differences among different NewSQL solutions. In this paper, we discuss the main features of the most prominent NewSQL products, besides we present benchmarking results for analyzing their performance. We believe that both analysis can be useful as a guide to a future choice of NewSQL technologies.
