fsttable-package: Lightning Fast Serialization of Data Frames for R.

In fstpackage/fsttable: Interface to on-disk data manipulation on fst files

Description

Multithreaded serialization of compressed data frames using the 'fst' format. The 'fst' format allows for random access of stored data which can be compressed with the LZ4 and ZSTD compressors.

Details

The fst package is based on three C++ libraries:

• fstlib: library containing code to write, read and compute on files stored in the fst format. Written and owned by Mark Klik.

• LZ4: library containing code to compress data with the LZ4 compressor. Written and owned by Yann Collet.

• ZSTD: library containing code to compress data with the ZSTD compressor. Written by Yann Collet and owned by Facebook, Inc.

The following copyright notice, list of conditions and disclaimer apply to the use of the ZSTD library in the fst package:
