> ColumnSize inside RecordBatchSizer while computing the totalDataSize for VariableWidthVector throws IndexOutOfBoundException when the underlying vector is empty without any allocated memory.
> This happens because the way totalDataSize is computed is using the offsetVector value at an index n where n is total number of records in the vector. When vector is empty then n=0 and offsetVector drillbuf is empty as well. So while retrieving value at index 0 from offsetVector exception is thrown.
