RDataSource currently does not support reading fixed/variable size arrays from RRootDS. I am not sure how RDataSource reads fixed/variable size arrays from other sources like CSV, Arrow, etc. It would be nice to add this feature in RRootDS and allows RDataFrame to read arrays from RRootDS.

the data source reads arrays as ROOT does and an idea could be to expose them as RVec instances. It should not be a big change.
