########## learning/prompts/documentation-lookup/08_basic_windowing.md: ########## @@ -0,0 +1,28 @@ +Prompt: +What is Windowing in Apache Beam? +Response: +Windowing is a key concept in stream processing, as it allows you to divide streams of data into logical units for efficient and correct parallel processing. +With an unbounded data set, it is impossible to collect all of the elements, since new elements are constantly being added. In the Beam model, any PCollection (including unbounded PCollections) can be subdivided into [logical windows](https://beam.apache.org/documentation/programming-guide/#windowing-basics). Grouping transforms then consider each PCollection’s elements on a per-window basis. Review Comment: Done -- This is an automated message from the Apache Git Service.
