v1.0.3

Highlights

Yi-aligned DiskANN update path, coroutine-based async I/O, and search hot-path optimizations — targeting 100M+ scale search throughput.

What's New

Query-level coroutine pipelining

search_pipelined() drives concurrent query coroutines over a shared io_uring reactor. Each query suspends on beam-wave reads instead of parking a thread; throughput follows Little's law. Requires update_io=uring.

Batched PQ distance kernel

pq_distance_batch() gathers code rows into a contiguous stack tile with software prefetch, then accumulates chunk-major so the dist_table row stays L1-hot. Eliminates the per-neighbor dependent random 32B code fetch that dominated eval at 100M scale. Bit-identical to the scalar path.

Coroutine async update I/O

The update path uses a cooperatively-polled io_uring reactor for asynchronous disk I/O, replacing blocking threads during page reads/writes.

Unified page pool

Searches peek and fill the shard page cache, so hot pages written by updates are visible to subsequent searches without cold reads.

Performance improvements

• Dirty-word visited bitset: clear() costs O(words set) instead of full-array memset, removing ~12MB per-query DRAM bandwidth wall at 100M slots.
• Page cache node recycling: at steady-state capacity, write() splices the LRU victim's map node and 4KB buffer in-place instead of erase+alloc.
• Tombstone snapshot skip: make_search_snapshot() skips bitmap copy when count is zero — zero overhead on the common post-compaction path.

Build & tooling

• Modular CMake rewrite with presets-based layout
• Official Conan dependency provider replaces hand-rolled scripts
• make format now routes through pre-commit pinned formatters (no more version-drift)
• Python runtime dependencies corrected; rag subpackage repaired

Fixes

• Portable alaya::prefetch_l3() replaces __builtin_prefetch for MSVC compatibility
• io_engine.hpp adds <io.h> and ssize_t typedef for Windows builds
• uring_reactor_test gated behind Linux platform check
