Time series data is everywhere: IoT, sensor data, financial transactions. The industry has moved to databases like Cassandra to handle the high velocity and high volume of data that is now common place. However data is pointless without being able to process it in near real time or do batch analytics.
That’s where Spark combined with Cassandra comes in, what was one just your storage system can be transformed into your analytics system, and you’ll be surprised how easy it is!
