  The Belle II experiment at the SuperKEKB accelerator is a next-generation
B-factory aiming to collect 50 ab$^{-1}$, about 50 times the data collected at
Belle, to study rare processes and make precision measurements that may expose
physics beyond the Standard Model. Corresponding to roughly 100 PB of storage
for raw data, plus dozens of PBs per year for Monte Carlo (MC) and analysis
data, these massive samples require careful planning for the storage,
processing, and analysis of data. This white paper notes some of the challenges
that await grid-based user-analysis at the intensity frontier and invites
further discussion and exploration to improve the tools and techniques
necessary to leverage the massive data samples that will be available at Belle
II as part of the Snowmass process.
