You can use Transducers.jl for this (disclaimer: I’m the author):

> [@Thread- and process-based parallelisms in Transducers.jl (+ some news)](https://discourse.julialang.org/t/thread-and-process-based-parallelisms-in-transducers-jl-some-news/32285/1):

> Transducers.jl now can be used to create various table types from DataFrames.jl, TypedTables.jl, StructArrays.jl, etc. See [`copy`](https://tkf.github.io/Transducers.jl/dev/manual/#Base.copy) and its parallel versions [`tcopy`](https://tkf.github.io/Transducers.jl/dev/manual/#Transducers.tcopy) and [`dcopy`](https://tkf.github.io/Transducers.jl/dev/manual/#Transducers.dcopy).
