Hey I'm the author of this blog post and the CEO of the company that did the benchmark report. That was a very poor choice of words on my part, and I appreciate you flagging it. I reworked the paragraph to remove the janitor comment and (hopefully) make it clearer.
I agree that it's a bad idea to use "janitor" as a disparaging term, and that was very far away from my intention. If that was what you took away from reading it, then that's more evidence that I didn't do a great job with writing the original draft.
Here's the original paragraph for reference:
Data engineers are the janitors who keep your data clean and flowing. Insights are great, and you need them. But to deliver insights at scale, you need data infrastructure. That’s delivered by data engineering. It’s not as fun to talk about as D3 visualizations and business intelligence dashboards, but it’s every bit as important.
