Interview Prompt
We're a data services company and our enterprise client sends us two kinds of data: a continuous stream of transactions throughout the day, and a large daily batch file that reconciles and corrects the day's activity. Both need to land in the same warehouse and both matter to the analysts. Design a pipeline that handles both paths.
