We have a new post up exploring memory mapping and the new Apache Arrow data format via Clojure and A few times in my career I have used memory mapping and found it both simpler and faster than stream-based IO. Using it we can 'load' datasets far larger than physical RAM or load only 1 column/row out of many in a dataset without loading the rest. We hope you enjoy this simple demonstration!
