Is it possible for multiple values to be stored in one data storage bucket?

Yes, in data warehouses using the bucket concept (for example, in hash tables or distributed storage systems), a single bucket can store multiple values. This occurs when different keys hash to the same bucket — this situation is called a collision.

To handle collisions, different methods are used:

• Chaining — the bucket contains a list or another structure holding all elements with the same hash value.
• Open addressing — in case of collision, the next free bucket is searched according to a certain algorithm.

Thus, a bucket is not necessarily a single value, but rather a container that can hold multiple elements in case of collisions.
