Description

When a RowGroup is added with AppendRowGroup, it must be filled with exactly the number of rows specified, or an exception will be thrown.

It should be possible go back and modify the RowGroupSize metadata after a column has completed prematurely. This would be useful in scenarios where the total number of rows to be written is not known in advance.
