Structured Streaming Internals
With Lakehouse as the future of data architecture, Delta becomes the de facto data storage format for all the data pipelines. By using delta, to build the curated data lakes, users achieve efficiency and reliability end-to-end. Curated data lakes involve multiple hops in the end-to-end data pipeline, which are executed regularly (mostly daily) depending on the need. As data travels through each hop, its quality improves and becomes suitable for end-user consumption. On the other hand real-time capabilities are key for any business and an added advantage, luckily Delta has seamless integration with structured streaming which makes it easy for users to achieve real-time capability using Delta. Overall, Delta Lake as a streaming source is a marriage made in heaven for various reasons and we are already seeing the rise in adoption among our users.
In this talk, we will discuss various functional components of structured streaming with Delta as a streaming source. Deep dive into Query Progress Logs(QPL) and their significance for operating streams in production. How to track the progress of any streaming job and map it with the source Delta table using QPL. What exactly gets persisted in the checkpoint directory and its details. Mapping the contents of the checkpoint directory with the QPL metrics and understanding the significance of contents in the checkpoint directory with respect to Delta streams.
