retrography / parallelRDS.R

Last active May 20, 2022 12:45 — forked from russellpierce/parallelRDS.R

Parallelize RDS compression/decompression to improve serialization performance in R

	# The functions below use parallelized versions of gzip, xz, and bzip2 to
	# improve compression/decompression performance of RDS serialization in R.
	# Each function searches for the appropriate program (based on the required
	# compression format) and if found, offloads the compression handling to the
	# external program and therefore leaves R free to do the data import/export.
	# The two main functions (saveRDS and readRDS) mask R's native read and write
	# functions. The functions have been only tested on macOS, but they must work
	# on any Linux/Unix.
	#
	# Requires the following packages: pxz, pbzip2, and pigz.
