Try: perform I/O with Uproot #50

Closed maxgalli closed 4 years ago

Try to perform the I/O part with Uproot https://github.com/scikit-hep/uproot4 and check whether there is a speed improvement, and how much it is. If this is huge, it is probably worth inserting a dependency in order to gain something in performance.

After brief investigation, it doesn't seem possible to mix the two worlds, i.e. perform the I/O with uproot and feed RDataFrame (which specifically takes TChains in the current implementation of the software). Closing.
