Li Liu 96c7ef094a enhance: Go search path optimizations for improved QPS (#47734) ... issue: #47827 Key optimizations: - O(1) task lookup in scheduler via unissuedTasksIndex map - Channel→indexed slice in searchSegments, eliminating channel alloc/sync - Single segment fast path skipping errgroup/goroutine overhead - Single channel fast path in LB policy - Shallow copy SearchRequest instead of proto.Clone deep copy - Pipeline.String()→p.name in debug log to avoid eager evaluation - TimeRecorder: fix double time.Now(), pre-compute logLabel, IsRecording guard - Batch 2D array allocation for resultOffsets in search reduce - Pre-allocate Scores/Topks slices with nq*topk capacity - Replace fmt.Sprint(nodeID) with paramtable.GetStringNodeID() on hot paths - Eliminate fmt.Sprintf in CtxElapse calls, use static strings Signed-off-by: Li Liu <li.liu@zilliz.com> Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>		2026-02-24 22:12:47 +08:00
