Duarte Nunes of ScyllaDB Discusses Materialized Views at ScyllaDB Summit 2017

At the ScyllaDB Summit 2017, Duarte Nunes, a software engineer at ScyllaDB with expertise in concurrent programming and distributed systems, discussed the implementation of Materialized Views in ScyllaDB. Materialized Views in ScyllaDB are designed to optimize data access by storing a subset of columns from a base table, enabling diverse query capabilities while ensuring consistency between view and base tables. Nunes highlighted the challenges of supporting these views in a multi-master, eventually consistent environment, where decentralization is key to maintaining cluster availability and minimizing latency. The talk delved into the design and algorithmic strategies employed to manage update propagation and ensure consistency, particularly addressing the challenges posed by concurrent updates. Attendees interested in distributed algorithms and ScyllaDB's architecture were the primary audience for this technical discussion, and further insights were available through ScyllaDB's public Slack and mailing list.
