In this short demo we showcase stream joins, our new feature that enables you to do stateful data transformations in Matterbeam.
đź“Ť
Stream joins are often used in situations where data from one stream needs to be enriched with data from another stream, as well as for various other analytics use cases.
In this demo we cover:
Creating stream joins within transforms by joining data from separate datasets, all directly in the UI
Writing and editing a custom transform using the UI Python code editor
