Abstract

The talk will present a new system and protocol for scaling out transactional processing.

The talk will describe why traditional and current systems fail to scale, and how LeanXcale has managed to overcome the bottlenecks of current systems.

The approach to scale out transactions relies in separating the commit of transactions from the visibility of the committed state. In this way, transactions can fully in parallel without any coordination removing any bottleneck.

The regulation of the visibility of the committed state enables applications to observe a consistent state despite the uncoordinated commitment of the transactions. The approach additionally scales out each of the ACID properties independently but in a composable way.

Speaker's biography

Professor Ricardo Jimenez-Peris is Director of the Distributed Systems Lab at Technical University of Madrid (UPM). He has co-authored a book on scalable database replication and a number of papers and articles at international conferences and journals, and is co-inventor of several patents. He has devoted most of his scientific career to study how to scale transactional processing and data management and provide high availability. He is technical coordinator of the CumuloNimbo, CoherentPaaS and LeanBigData European projects. He is now co-founding a startup that will commercialize the result of this research.
