The Workshop on Principles and Practice of Consistency for Distributed Data will take place on April 18, 2016, in London, UK, and is co-located with the EuroSys 2016 conference. It is the direct successor of the EuroSys 2015 Workshop on Principles and Practice of Consistency for Distributed Data which brought together approximately 40 researchers and practitioners in the areas of distributed systems, programming languages, databases and concurrent programming.This workshop aims to investigate the principles and practice of weak consistency models for large-scale, distributed shared data systems. It will bring together theoreticians and practitioners from different horizons: system development, distributed algorithms, concurrency, fault tolerance, databases, language and verification, including both academia and industry.
