Tutorials and Talks

Talk "NoSQL Databases - An Overview" at Data Natives 2015 in Berlin.

Talk "Replication and Synchronization Algorithms for Distributed Databases" at Distributed Matters 2015 in Berlin.
Abstract:
This talk will provide in-depth background on strategies for replication and synchronization as implemented in modern distributed databases. The following topics will be covered: master-slave vs multi-master replication; epidemic protocols; two-phase commit vs Paxos; multiversion concurrency control; read and write quorums. A concise overview of implementations in current NoSQL databases will be presented.
