# Redis system design | Distributed cache System design

**[Tech Dummies - Narendra L](https://daily.dev/sources/techdummies)** · 34 min read · 0 upvotes · 0 comments

## Summary

A walkthrough of distributed cache system design covering core concepts and implementation details. Topics include cache access patterns (write-through, write-around, write-back), hash table internals with collision handling, LRU eviction policy implemented using a hash table combined with a doubly linked list for O(1) operations, event-driven request handling with thread pools, persistence strategies (snapshots and log reconstruction), and high availability through master-slave replication with consistent hashing for horizontal scaling.
