Chapter 5. Efficiency and Scalability
In this final chapter, we focus on the crucial aspects of optimizing and scaling the data pipelines we’ve developed. We start by defining what we mean by “efficiency” and “scalability” to set the boundaries for our discussion.

The chapter culminates with a dual-focused discussion. First, we explore the process of collaboration, particularly how to scale effectively in terms of team size and skill set. Second, we delve into creating an optimal developer experience, a key factor in efficient data pipeline management.
