Tutorial 3c – GroupBy, GroupByKey, CoGroupByKey and GroupIntoBatches Transform in Apache Beam

github url: https://github.com/vigneshSs-07/Cloud-AI-Analytics/tree/main/Apache%20Beam%20-Python In this videos we are going to discuss about what is Transformations - GroupBy, GroupByKey, CoGroupByKey and GroupIntoBatches. GroupBy: ● Takes a collection of elements and produces a collection grouped, by properties of those elements. GroupByKey: ● GroupByKey is a Beam transform for processing collections of key/value pairs. ● Takes a keyed collection of elements and produces a collection where each element consists of a key and all values associated with that key. CoGroupByKey: ● While GroupByKey performs this operation over a single input collection and thus a single type of input values, CoGroupByKey operates over multiple input collections. ● CoGroupByKey expects a dictionary of named keyed PCollections, and produces elements joined by their keys. GroupIntoBatches: ● Batches the input into desired batch size.
