  Analysis cyberinfrastructure refers to the combination of software and
computer hardware used to support late-stage data analysis in High Energy
Physics (HEP). For the purposes of this white paper, late-stage data analysis
refers specifically to the step of transforming the most reduced common data
format produced by a given experimental collaboration (for example, nanoAOD for
the CMS experiment) into histograms. In this white paper, we reflect on
observations gathered from a recent experience with data analysis using a
recent, python-based analysis framework, and extrapolate these experiences
though the High-Luminosity LHC era as way of highlighting potential R\&D topics
in analysis cyberinfrastructure.
