Description

Saves arbitrary large object to disk using saveRDS. If compression is 'xz', then the file is first saved quickly with no compression, and then the background process is spawned that compresses the file in multithreaded fassion using 'pxz', if the program is available.

Usage

save_large_object(obj, file, compress = "xz", wait_for = c("save",
  "compress", "none"), flag_use_tmp_storage = FALSE,
  fn_to_run_after_save = NULL, fn_to_run_after_compress = NULL,
  parallel_cpus = NULL, flag_detach = FALSE)

Arguments

obj	The object to be saved
file	Path to the file
compress	Compression method with the same meaning as saveRDS. Default is 'xz'.
wait	If set the function exits only after the object is available to read.
fn_to_run_afters_save	Function that will be run after save. The function will get a single argument - path to the newly created file

Value

parallel job with the backgroud save, if wait is not 'none'
