Online Learning with Structured Streaming

Download Slides

Structured Streaming is a new API in Spark 2.0 that simplifies the end to end development of continuous applications. One such continuous application is online model updates: Online models are incrementally updated with new data and can be continuously queried while being updated. As a result, they can be fast to train and leverage new data faster than offline algorithms. In this talk, we give a brief introduction the area of online learning and describe how online model updates can be built using structured streaming APIs. The end result is a robust pipeline for updating models that is scalable, fast and fault tolerant.
