About Data Pipelines

Lars dove into data pipelines, and emerged bearing arrows and wishing for a lot fewer copies.

What is there to think about regarding data pipelines, what is interesting about them?

Which tools are out there, and why might you want to use them?

Why all this talk about making fewer copies of data?

What does Lars' current ideal pipeline look like, and where does Elixir fit in?
