gatherNext(n: Int): ColumnarBatch

def
getBitSizeMap(n: Int): ColumnView
Get the bit count size map for the next n rows to be gathered.
Get the bit count size map for the next n rows to be gathered. It returns a column of INT64 values. One for each of the next n rows requested. This is a bit count to deal with validity bits, etc. This is an INT64 to allow a prefix sum (running total) to be done on it without overflowing so we can compute an accurate cuttoff point for a batch size limit.
