Spotify has built several real-time pipelines using Apache Storm for use cases like ad targeting, music recommendation, data visualization, and notifications. Each of these real-time pipelines have Apache Storm wired to different systems like Apache Kafka, Apache Cassandra, Apache Zookeeper, and other sources and sinks. In this talk the speaker, Kinshuk Mishra, will share his experiences of scaling Apache Storm pipelines at Spotify. The talk will cover the topics such as Spotify's data architecture, best practices, caching, tuning event sources and sinks, monitoring pipeline health and miscellaneous optimizations to make Apache Storm pipelines more robust.
