v2.13.0
7c60a65

Highlights

  • Bounds the default idle RDMA connection pool at 16 QPs per node and lane instead of 256. This retains 2x headroom for the measured SGLang C32 fan-out while preventing transient thread spikes from retaining enough idle QPs to consume the server shared receive segment.
  • Records the resolved DFKV_RDMA_POOL_MAX value in the startup configuration dump. Workloads that prove connection churn can still raise the value explicitly.
  • Aligns the dfkv-common, LMCache, and vLLM connector package versions and dependency pins with 2.13.0.

Compatibility

  • No protocol or data-format change.
  • DFKV_RDMA_POOL_MAX remains configurable and accepts the same values; only its default changes from 256 to 16.
  • Portable artifact is statically linked with libstdc++; observed GLIBC floor is 2.34.

CI

All main-branch CI jobs passed: GCC, Clang, ThreadSanitizer, RDMA compile, RDMA datapath workflow, runtime deployment smoke, connector wheels, and portable static artifacts.
