In this blog post, we will introduce Spark, a unified analytics engine for large-scale data processing, and discuss how to use it to do SQL on a NoSQL database like Cassandra. We will also give you a quick demo to show how you can quickly test it out yourself. This is Part 2 of our series on “Doing SQL and Reporting on Apache Cassandra with Open Source Tools”, and part 1 is linked below. Also, be on the lookout for Parts 3 and 4 coming soon!
