👉 Cache veins are a type of data structure that is used to represent the connections between different sets of data within a database or other complex data structures. They are essentially a collection of pointers or references to related data blocks, allowing for efficient and fast access to related data without having to scan through all the data repeatedly. Cache veins are typically implemented as hash tables or other data structures optimized for quick lookups. By using cache veins, applications can significantly reduce their memory footprint and improve performance by minimizing redundant data accesses.
