The fastest delimited reader for R, 1.27 GB/sec. vroom doesn’t stop to actually read all of your data, it simply indexes where each record is located so it can be read later. The vectors returned use the Altrep framework to lazily load the data on-demand when it is accessed, so you only pay for what you use. This lazy access is done automatically, so no changes to your R data-manipulation code are needed.

A simple library for parsing CSV in Java, based on the OpenCSV library. After trying unsuccessfully to fix some of the key bugs in OpenCSV, I concluded that the core of the library -- the CSVParser -- was too complicated a patchwork to salvage. I decided to rewrite it.
