Is it possible to controll the number of RHDG cache entries by the size of the persistence store

Issue

• We want to prevent that filesystem for leveldb, rocksdb or filestore get filled and cause issues, is that possible?
• Is there a setting for expiration which is based on the size of the cache?
• Can we use a 'kind of eviction' for leveldb cache-store in remote client server? Is there any other way to prevent that leveldb storage got filled?
• With eviction there is a method to prevent memory to be overused, is there a method to do the same vor a persistence store?
