Hash-based indexing is a technique used to store and retrieve records efficiently by mapping keys to specific locations using a hash function. Unlike tree-based indexing, which organizes data hierarchically, hash-based indexing directly maps keys to buckets or slots, making it particularly efficient for point queries.

What Is Hash-Based Indexing?

Hash-based indexing employs a hash function to compute a hash value for each key, determining the bucket or slot where the corresponding record will be stored
