Hi there,

you may be interested in this thread [Best Data Manipulation packages 2020-09 [video]](https://discourse.julialang.org/t/best-data-manipulation-packages-2020-09-video/46690)

Lazy.jl can give you lazy evaluation: [https://github.com/MikeInnes/Lazy.jl](https://github.com/MikeInnes/Lazy.jl)

And then there is Transducers.jl and the things that use it, not lazy AFAIK but pretty cool: [GitHub - JuliaFolds/Transducers.jl: Efficient transducers for Julia](https://github.com/JuliaFolds/Transducers.jl)
