How vLLM schedules requests and manages the KV cache
An article published on September 26, 2026 follows a vLLM request from queue to decoding and explains per-iteration scheduling and KV-cache block allocation.
Published on September 26, 2026, the article follows a request in vLLM from the queue through prefill and decoding. It describes scheduling at each iteration and how PagedAttention allocates KV-cache blocks as sequences grow.
The article connects these mechanisms to batching and KV-cache memory management during inference. To check the details, consult the original article and compare its concepts with vLLM documentation or code; the available summary gives no measurements or quantitative results.
