i read your some code,i cann’t understand how to handle hash collision? if the frequency of collison is high， what potential problem is there?

google's hash function -- cith_hash_128, has very good hash value output on your keys if they are not too short. based on this, the bucket order of high_load_factor_hash_table -> low_load_factor_hash_table -> very_small_full_search_array can work well.
