Hi, this is a quick note for whomever is in charge of the wiki (my wiki account no longer has write ability)
Built-In_Reduce_Functions says that you need to emit numbers for the _sum operation. As of 1.2.x, this can also be a list of numbers. I just emitted a list of numbers and got what I expected...that is, a sum over each element of the list (not a summing up of the elements, summed. Example: no reducing, I emit a list of 4 items for each key: ["2007-02-27", "1213122", "2007-02-27 14:46:00 UTC"] [0.000007830687904038072, 0.000001032961291729275,0.0000012756780418961, 2.209310910297831e-7] ["2007-02-27", "1213122", "2007-02-27 14:46:30 UTC"] [0.000008151766266816958, 0.000001042421330553939,0.000001315925015500657, 2.278253064474915e-7] "Exact" reducing, same as emit with no reduce: ["2007-02-27", "1213122", "2007-02-27 14:46:00 UTC"] [0.000007830687904038072, 0.000001032961291729275,0.0000012756780418961, 2.209310910297831e-7] ["2007-02-27", "1213122", "2007-02-27 14:46:30 UTC"] [0.000008151766266816958, 0.000001042421330553939,0.000001315925015500657, 2.278253064474915e-7] level=1 reducing, summing up over each day ["2007-02-27"] [0.003547119931415267, 0.005496433891250249, 0.007064010452051014,0.003552803842322634] ["2007-02-28"] [0.008437247339553495, 0.01664606221946668, 0.01779585111017863,0.01036210620457586] I observed this behavior in 1.2.x. I know this hasn't always been a feature, but I couldn't find whether it was 1.1 or 1.0, or what. Regards, James Marca
