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.
TensorRT-LLM's v1.4.0rc1 release candidate, released October 22nd, lists an integration with Mooncake Store for sharing KV-cache prefixes across serving instances. Mooncake's project update dates the merge to October 10th.…
