DescriptionCACHE_STORAGE_PERCENTAGE Environment Variable

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. Humio 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.
