02-02-2019 Full Totem Analysis based on RDataFrame and distributed on a big Spark cluster with PyRDF!
Milosz Blaszkiewicz and Aleksandra Mnich (AGH University of Science and Technology - Poland) wanted to evaluate a set of Big Data tools for the analysis of the data from the TOTEM experiment which will enable interactive or semi-interactive work with large amounts of data. They ended up re-implementing a full Totem analysis in a declarative fashion using RDataFrame and distributing their calculations over a big Spark cluster with PyRDF.

11-07-2018 RDataFrame session at CHEP 2018

Join the CHEP 2018 BOF to discuss bout the Future of ROOT Based Analysis: sign up here and visit the indico agenda.

Too much data? Too many cores? TTree analysis is tedious? Come and enjoy an intro plus discussion of RDataFrame, ROOT's current-generation way of writing super-efficient analyses! It moves all the intricacies into ROOT's responsibility, leaving you simply with a declarative formulation of the filters and computations that make up your analysis.
