| Variable | CACHE_STORAGE_PERCENTAGE | |
| Description | Enable caching of files from a slow network file system (EBS) or for a file system on spinning disks | |
| Default | 90 | |
Enable caching of files from a slow network file system (EBS) or for a
file system on spinning disks. The cache should be placed on local NVME or
similar drives, providing more than 200 MB/s/core in the machine.
CACHE_STORAGE_PERCENTAGE Defaults to 90 and controls how
full the cache file system is allowed to become. LogScale manages the
files in the cache directory and will delete files when there is too
little space remaining. (Do not add a RAM-disk as cache: RAM is better
kept for page cache.) Caching is disabled by default as most install do
not benefit from turning it on.
See CACHE_STORAGE_DIRECTORY above for an example of this
variable and more information.
