WebMar 28, 2024 · Disadvantages of Hash: Hash is inefficient when there are many collisions. Hash collisions are practically not be avoided for large set of possible keys. Hash does not allow null values. Hash tables have a limited capacity and will eventually fill up. Hash tables can be complex to implement. WebNov 2, 2024 · Disadvantages: The cache performance of chaining is not good as keys are stored using a linked list. Open addressing provides better cache performance as everything is stored in the same table.
