A value in the range (0.0, 1.0) that specifies the fractional point at
which the original stream should be split. The actual split point is
evaluated on pre-filtered rows, so if a filter is provided, then there is
no guarantee that the division of the rows between the new child streams
will be proportional to this fractional value. Additionally, because the
server-side unit for assigning data is collections of rows, this fraction
will always map to to a data storage boundary on the server side.
