Real-time data is becoming increasingly important in today’s fast-paced business world, as companies seek to gain valuable insights and make informed decisions based on the most up-to-date information available. However, processing and analyzing real-time data can be a challenge, particularly when it comes to joining multiple streams of data together in real-time. In this article, we’ll explore the concept of multi-stream joins in SQL, and discuss some tips and techniques for performing these joins effectively using a streaming database.
A multi-stream join involves combining two or more streams of data together in real-time to create a single output stream that reflects the current state of the data. This can be a powerful technique for analyzing real-time data from multiple sources, such as IoT devices, social media feeds, e-commerce apps, or financial markets.
