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
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.
