Description

In https://github.com/NVIDIA-NeMo/Curator/pull/1630, we added errors and warnings about the blocksize or files_per_partition parameter being too large. However, those checks are only on the storage size of the data file(s), which can expand greatly in memory. We should consider adding more checks and warnings about the DocumentBatch.data size(s) once they are loaded in memory.
