    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. Darwin: Scale-In Stream Processing

    ·

    In the 99th reading group meeting, we discussed stream processing. The paper we read, “Darwin: Scale-In Stream Processing” by Lawrence Benson and Tilmann Rabl, argues that many stream processing systems are relatively inefficient in utilizing the hardware. These inefficiencies stem from the need to ingest large volumes of data to the requirement of durably storing…

    “Achieving High Throughput and Elasticity in a Larger-than-Memory Store” paper by Chinmay Kulkarni, Badrish Chandramouli, and Ryan Stutsman discusses elastic, scalable distributed storage. The paper proposes Shadowfax, an extension to the FASTER single-node KV-store. The particular use case targeted by Shadowfax is the ingestion of large volumes of (streaming) data. The system does not appear…

    Our 93rd paper in the reading group was “ByShard: Sharding in a Byzantine Environment” by Jelle Hellings, Mohammad Sadoghi. This VLDB’21 paper talks about sharded byzantine systems and proposes an approach that can implement 18 different multi-shard transaction algorithms. More specifically, the paper discusses two-phase commit (2PC) and two-phase locking (2PL) in a byzantine environment.…
