WebROOT RDataFrame code. (b): PyRDF equivalent code: only the import directive changes. The goal of the package is to expose RDataFrame to a variety of distributed backends. The current implementation fully supports Spark, a widespread framework for cluster computing [5], and it is designed to be extensible to other backends. WebRDataFrame is ROOT’s high-level interface for efficient data analysis. With RDataFrame, it is possible to read, select, modify and write ROOT data, as well as easily produce histograms, cut-flow reports and other results.
