Streaming SQL is the latest hot technology that takes a fundamentally familiar topic and adds modern techniques. SQL is ubiquitous and probably will continue to be for a long time, so if you start with that foundation and add modern streaming functionality, you get a technology that is ideal for querying real-time data streams. The widespread familiarity of SQL will help with adopting it in new environments and new use cases.
As big data is shifting from a world at rest to a world in motion, more of our non-technical colleagues need to get involved with streaming data. This means we need visualization applications that have been architected to handle streaming systems for use cases like cybersecurity, IoT, and regulatory compliance. After all, time is money, and the sooner you deliver insights the greater the impact.
