What is the role of buckets within the implementation of the Map data structure?

In the implementation of the Map data structure in Go (Golang), a bucket is an internal structure used to store key-value pairs. A Map in Go is implemented as a hash table, and a bucket is one of the elements of this table, containing several records.

When you add a key-value pair to a Map, the key is hashed, and the result of the hash function determines which bucket this pair will go into. Each bucket can contain multiple elements to handle collisions (when different keys have the same hash).

Thus, a bucket provides efficient storage and quick access to data, minimizing the number of comparisons when searching for a value by key.

It can be roughly represented as follows:

  • The Map contains an array of buckets.
  • Each bucket stores several key-value pairs.
  • When searching for a key, a hash is computed, a bucket is selected, and then the key is searched within the bucket.
