Quarantine DB Talk 2020: ksqlDB: A Stream-Relational Database System

Event Date: Monday November 23, 2020
Event Time: 05:00pm EDT
Speaker: Matthias J. Sax [INFO]

Title: KsqlDB: A Stream-Relational Database System

ksqlDB is a distributed event streaming database system that allows users to express SQL queries over relational tables and event streams. The project was released by Confluent in 2017 and is hosted on Github and developed with an open-source spirit. ksqlDB is built on top of Apache Kafka, a distributed event streaming platform.

In this talk, we discuss ksqlDB’s architecture that is influenced by Apache Kafka and its stream processing library, Kafka Streams. We explain how ksqlDB executes continuous queries, while achieving fault-tolerance and high-availability. Furthermore, we explore ksqlDB’s streaming SQL dialect, and the different types of supported queries.

This talk is part of the Quarantine Database Tech Talk Seminar Series.
