Yep, the Spark UI's Shuffle Write Size/Records" column can sometimes show
incorrect record counts *when data is retrieved from cache or persisted
data*. This happens because the record count reflects the number of records
written to disk for shuffling, and not the actual number of records in the

Just to further clarify that the Shuffle Write Size/Records column in
the Spark UI can be misleading when working with cached/persisted data
because it reflects the shuffled data size and record count, not the
entire cached/persisted data., So it is fair to say that this is a
limitation of the UI's
