It does not look like there are any compression options in libxgboost, and as such I don't think it's appropriate to add additional dependencies to this library for compression.
There is of course nothing stopping you from compressing the serialized output, see, for example TranscodingStreams.jl for a convenient way of doing this. For example, you can do something like
open(GzipCompressorStream, "booster.dat.gz", write=true) do io
XGBoost.save(booster, io)
end
to write the XGBoost model booster
to a file using gzip compression.
Thanks a lot for the suggestion!
Glad it helped. I'm going to close this now, but feel free to comment if you feel the interface could use improvement, as it was not really written with compression in mind. Again, I don't think it's a good idea to add a dependency, but there are always possibilities for small API tweaks and improvements.
I was wondering if compression can be added to the save booster saving method.
