Announcing Silk: a silky smooth fiber runtime for ClickHouse
Scored daily by a customisable AI persona to surface the most relevant engineering leadership news.
Silk fiber runtime for ClickHouse is a novel, technically deep project directly relevant to data engineering.
ClickHouse announced Silk, a stackful-fiber C++ library with a NUMA-aware work-stealing scheduler and io_uring as the I/O ground truth, designed to eliminate heap allocation in the steady-state hot path. Unlike OS threads or C++20 stackless coroutines, Silk yields in tens of nanoseconds and avoids cache aliasing issues that plagued prior fiber implementations like Alibaba's Photon. The first integration target is ClickHouse's distributed cache, targeting I/O-bound workloads where tail latency at the 99th and 99.9th percentile dominates query performance.
