Got you, thanks Neal. It does seem like it'll be tricky to implement in javascript without native compression. We've managed to trick our server to serve .feather.gz as .feather with compression headers, so we save on storage & runtime server compression, and the native browser http decompression.

FWIW the C++ compute library now uses https://github.com/JuliaStrings/utf8proc, so assuming it does all of the things you want, it could save you some trouble if you used it in Gandiva too--cmake is already set up to use it. Neal On Tue, Dec 22, 2020 at 3:41 PM Sagnik Chakraborty wrote: > We ar
