+- `max_size` - maximum size of the cache in bytes or in readable format, e.g. `ki, Mi, Gi, etc`, example `10Gi` (such format works starting from `22.9` version). When the limit is reached, cache files are evicted according to the cache eviction policy. Default: None, this setting is obligatory.
 
 - `cache_on_write_operations` - allow to turn on `write-through` cache (caching data on any write operations: `INSERT` queries, background merges). Default: `false`. The `write-through` cache can be disabled per query using setting `enable_filesystem_cache_on_write_operations` (data is cached only if both cache config settings and corresponding query setting are enabled).
