The use of machine learning in real-time environments is a complex problem that has not received enough attention from framework developers. Most frameworks support the "learning" part of machine learning but lack support for the "predict" side. Redis-ML, a module built into Redis 4.0.0, aims to address this gap by providing a native datatype for linear regression and other machine learning algorithms. The Redis-ML module uses the new Modules API to add standard machine learning commands, making it easier to implement real-time predictions in applications. By using Redis as a predictive engine, developers can build fast and reliable applications that can make predictions based on data stored in Redis.
