The Cost of Hash Tables - The Backend Engineering Show

Explore the costs and limitations of hash tables in this informative video from The Backend Engineering Show. Dive into the effectiveness of hash tables for caching, database joins, sets, load balancing, partitioning, and sharding. Learn about arrays, CPU costs (including NUMA and M1 Ultra), hash joins, and the remapping costs associated with hash tables. Discover the concept of consistent hashing and gain insights into the trade-offs involved in using this powerful data structure across various programming languages and applications.
