How is data stored in key-value format inside a bucket?

Data inside a bucket stored in key-value format is usually kept using a hash table or a balanced tree, which provides quick access by key.

An example implementation in Go might use the built-in map:

bucket := make(map[string]string)

// Adding data
bucket["key1"] = "value1"

// Retrieving data
value := bucket["key1"]

In more complex systems, a bucket could be a structure that stores key-value pairs with additional mechanisms for collision management and efficient searching.
