In the example below, what is the best way to define y without allocating x

Is this how it should be done?

using DataFrames
x=repeat(vcat("someString"),1_000_000));
y = DataFrames.PooledArrays.PooledArray(x)

invpool=Dict{String,UInt8}("someString"=>1)
pool=DataFrames.PooledArrays._invert(invpool)
refs=repeat(vcat(UInt8(1)),1_000_000)
y2 = DataFrames.PooledArray(DataFrames.PooledArrays.RefArray(refs),invpool,pool)

@assert isequal(y,y2)
