In our test case one of the steps involves caching a docker image into the file and restoring it later.
Problem is, if we cache a tar file, the script will compress it which is a time-consuming operation which doesn't really bring a big value.
Default cache command, provided by semaphore:
semaphore@semaphore-vm:~/app_cache_dir$ time tar czPf /tmp/app_image_cache-cac3c3500fc4aa1a4f8dece0edb86e57ad36510e.tar app-image.tar
real 0m34.813s
user 0m33.855s
sys 0m1.230s
without compression:
semaphore@semaphore-vm:~/app_cache_dir$ time tar cPf /tmp/app_image_cache-cac3c3500fc4aa1a4f8dece0edb86e57ad36510e.2.tar app-image.tar
real 0m0.708s
user 0m0.049s
sys 0m0.655s
The possible solution would be to provide a flag option to cache, like: cache store --compress=false my_file_or_directory which would add or remove z option from tar command.
