Size of void pointer or size of character pointer are same because both variable contain address or we can say memory location

It depends on the amount of primary memory one has for the process. If we can store 1 million records in primary memory, then we can very well take a hash table with a consistent hashing scheme for avoiding collisions. It will take O(1). 

In most cases however this is not possible. In circumtances like this, there are two ways:

B Trees or Extensible Hashing both of them have interesting time complexities.
