Yes, I see the same phenomenon. Could someone suggest a workaround
until this is fixed? I'm under the gun to submit output tables and the
only thing I can think of is a crawling slow loop to step through each
window twice: once using the plain aggregation and another without just
get all rows. I highly doubt it will be worthwhile, given it's going to
be about 1000 iterations, and each one would take about 30-45 min...
