[GitHub] [arrow-julia] quinnj commented on issue #340: Feather file with compression and larger than RAM

   Hmmmm......we'll have to see what we can do here. I've had the idea for a while as a Tables.jl-wide feature to support projection/filter push down for sources in a generic way. That would translate really well to Arrow and would allow us to more easily avoid decompressing when not necessary. There's probably more we can do in the short-term though to avoid materializing when not needed.
