SGLang's Radix Cache explained via LeetCode problems

The Radix Cache, a key component in SGLang's high-throughput LLM processing, optimizes performance by reusing computed KV cache prefixes across requests. This is achieved by storing these prefixes in a Radix Tree, similar to how an LRU cache manages entries. The implementation combines algorithms from classic LeetCode problems like LRU Cache and Kth Largest Element in a Stream to efficiently handle data eviction and retrieval. AI
