DataCategoryHashMap

What it does

This class provides a cached mapping of category IDs to their subcategory IDs in Magento 2's URL rewrite system.

Developers use it to efficiently retrieve all child categories for a given parent category without repeatedly querying the database, improving performance during URL rewrite generation.

It implements a hash map pattern with automatic cache invalidation and request-scoped reset capabilities.
