The Generic Hash Implementation Code Path: src/t_hash.c The generic hash type is a wrapper around listpack and dict, it will switch between two different implementation and call the routines accordingly. Listpack Implementation Code Path: src/listpack.c Listpack is a densed storage of a series of keys and values, it supports storing both integers and strings. If the hash size is lower than hash_max_listpack_value, it will be saved as a listpack. If the hash size is higher than hash_max_listpack_value, it will create a dict and copy the data from listpack to the dict....
