RDataFrame <-> awkward - example time series support (to be ported to separate github) Tools/RDataFrame

[miranov25]

ROOT team works on simplification of the user interface for RDataFrame as stated in the Root user workshop 2022.

• https://indico.fnal.gov/event/23628/

In the meantime, we will try prototyping using example Time series support on the top of the RDataFrame+RVec implementing part of the time series algorithm: https://bookdown.org/rdpeng/timeseriesbook/filtering-time-series.html

Preferred to use TClass to

• Define in RDtaFrame in internal namespace
• JITed only at the beginning
• slower after O(1000 lines)
