What are the consequences in the Map data structure if one of its buckets reaches maximum capacity and overflows?

In the Map data structure in Go, which is implemented based on a hash table with buckets, when one of the buckets overflows, it is expanded and elements are redistributed. When the number of elements in a bucket reaches a certain threshold, the following occurs:

• Increasing the number of buckets (usually doubling).
• Rehashing and redistributing all elements across the new buckets.

This helps maintain the efficiency of search, insert, and delete operations, preventing performance degradation due to a large number of collisions in a single bucket.

Thus, bucket overflow leads to redistribution of elements and increasing the hash table's capacity, ensuring stable Map performance.
