Subsection on dataframes_load_save about Arrow.jl

[storopoli]

Arrow seems the future of data storage. We should cover that also.

[lazarusA]

never actually used it before. Do you have some specifics? who/where/why/when is used?

[storopoli]

Especially in the context of big data, since it allows for out-of-memory (Hard Drive) data wrangling as fast as in-memory (RAM).

Take a look at https://arrow.apache.org/ and https://en.wikipedia.org/wiki/Apache_Arrow.

It is really fast to read and write data, while being overall highly-performant.

Let's only add this if one of us actually used Arrow in a real-world use-case?

[storopoli]

Yes, that's why I have not labelled this with any version.
