Joins are a common and well-understood operation in batch data processing to connect the records of two data sets based on a relationship. However, the semantics of joins on dynamic data streams (data in-motion) are much less obvious or even confusing.

Stream processing presents a complex paradigm of matching data in motion to achieve meaningful correlation of data points.


In this guide, we will walk you through:

• Various components and complexities of Streaming Joins
• How to simplify Streaming Joins execution with accuracy and speed.
