When set to `map` the cache files will be updated in real time (check `man mmap` - do not set this on systems with heavy load or slow disks - the disks will continuously sync the in-memory database of netdata). When set to `dbengine` it behaves similarly to `map` but with much better disk and memory efficiency, however, with higher overhead.
