TensorRT-LLM adds Mooncake cache sharing to its v1.4 release candidate

NVIDIA's TensorRT-LLM v1.4.0rc1 release candidate, published October 22nd, lists an integration with Mooncake Store that lets serving instances share KV-cache prefixes, with Mooncake's project update dating the merge to October 10th. The connector trades repeated prompt computation for shared host-memory capacity and KV-transfer overhead, and operators must weigh those costs against the GPU KV capacity still needed to serve cache hits.

By Ryan Merket https://runtimewire.com/author/ryan-merket · Published Primary source: The Cloudflare Blog https://blog.cloudflare.com/kv-cache-exposure-remediation/ Why it matters Shared prefix reuse can cut repeated prompt computation when requests arrive at different serving instances. Operators must weigh that potential saving against host-memory reservations, transfer copies and the GPU KV capacity still required to serve cache hits.
