These settings are available in system.settings and are autogenerated from source.
enable_filesystem_cache
Use cache for remote filesystem. This setting does not turn on/off cache for disks (must be done via disk config), but allows to bypass cache for some queries if intended
enable_filesystem_cache_log
Allows to record the filesystem caching log for each query
enable_filesystem_cache_on_write_operations
Enables or disables write-through cache. If set to false, the write-through cache is disabled for write operations. If set to true, write-through cache is enabled as long as cache_on_write_operations is turned on in the server config’s cache disk configuration section.
See “Using local cache” for more details.
Cloud default value: 1.
enable_filesystem_read_prefetches_log
Log to system.filesystem prefetch_log during query. Should be used only for testing or debugging, not recommended to be turned on by default
