Slides: http://www.slideshare.net/DataStax/lessons-from-cassandra-spark-matthias-niehoff-stephan-kepser-codecentric-ag-c-summit-2016 | We built an application based on the principles of CQRS and Event Sourcing using Cassandra and Spark. During the project we encountered a number of challenges and problems with Cassandra and the Spark Connector. In this talk we want to outline a few of those problems and our actions to solve them. While some problems are specific to CQRS and Event Sourcing applications most of them are use case independent.
