Performance of creating a demo dataset

using InMemoryDatasets

function demo_data()
    n = 100000
    time = 0.1:0.1:n*0.1
    d1 = rand(Int8(11):Int8(40), n)
    d2 = 21:n + 20
    d3 = rand(Int8(31):Int8(60), n)
    ds = Dataset(time=time, d1=d1, d2=d2, d3=d3)
    ds.d1[5] = missing
    ds
end

demo_data()
@time ds=demo_data()

This looks quite nice… Only 2 to 8 ms instead of 5s! :slight_smile:

So a for loop is not always a good idea…
