Big Data was about being able to store and query data beyond the limits of a single machine or existing database. The point being to store as much data as you possibly can and then extract value out of it. That grew out of Hadoop/MapReduce which let you cheaply store and access data that doesn't fit into one machine. Streaming was not part of the initial marketing pitch. That said if you want to do streaming nowadays then you just integrate with Segment. If you want to track your database then you can dump data using Fivetran. If you want to track client events in excruciating detail then you can use Fullstory/Heap to do so in real time. That's all now table stakes for any company and outsourced to those platforms.
