Reading Group Special Session: Scalability and Fault Tolerance in YDB
YDB is an open-source Distributed SQL Database. YDB is used as an OLTP Database for mission-critical user-facing applications. It provides strong consistency and serializable transaction isolation for the end user. One of the main characteristics of YDB is scalability to very large clusters together with multitenancy, i.e. ability to provide an isolated user environment for…

Reading Group Special Session: Fast General Purpose Transactions in Apache Cassandra
Modern distributed databases employ leader-based consensus protocols to achieve consistency, entailing certain trade-offs: typically either a scalability bottleneck or weak isolation. Leaderless protocols have been proposed to address these and other shortcomings of leader-based techniques, but these have not yet materialized into production systems. This paper outlines compromises entailed by existing leaderless protocols versus leader-based…
