Talk: Robert Kubis (Spanner – a fully managed horizontally scalable relational database with ACID transactions that speaks SQL)

Google Developer Advocat Robert Kubis will talk about the global distributed NewSQL database Spanner at April 3 16:40-18:10 room APB E008. The talk is part of the Architektur von Datenbanksystemen II lecture.

Abstract

Live coding and demos! In this presentation you’ll learn what Spanner is all about! I’ll talk about TrueTime, horizontal scale, the CAP theorem and best practices. You’ll see how to setup your first Spanner instance and database. We walk through design decisions when coming up with your schema and queries that are enabled to scale to terabytes. Come prepared to see some code, queries and query explains.
