compress_folder
Wrap tar
compression command.
This module is used both locally (in the environment where fractal-server
is running) and remotely (as a standalon Python module, executed over SSH).
This is a twin-module of extract_archive.py
.
The reason for using the tar
command via subprocess
rather than Python
built-in tarfile
library has to do with performance issues we observed
when handling files which were just created within a SLURM job, and in the
context of a CephFS filesystem.
