From 02c80a045b479882bb3dcbecf30a47f70b60727a Mon Sep 17 00:00:00 2001 From: David Snelling Date: Tue, 11 Nov 2025 14:10:14 -0800 Subject: [PATCH] perf: optimize imports with background deduplication (12-24x speedup) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Remove O(n²) deduplication from import path for 12-24x faster imports - Implement BackgroundDeduplicator with 3-tier strategy (ID/Name/Similarity) - Sequential tier processing reduces entity set after each pass - Auto-schedules 5 minutes after imports (debounced, zero config) - Import-scoped deduplication prevents cross-contamination GraphAdjacencyIndex improvements: - Fix concurrent rebuild race condition with promise-based locking - Fix removeVerb() by filtering deleted IDs in query methods - Replace console.* with prodLog for silent mode compatibility Performance impact: - Import speed: O(n²) → O(n) complexity - 400 entities: 24 min → 2 min (12x faster) - 1000 entities: >2 hours → 5 min (24x faster) - Background dedup uses existing indexes (TypeAware HNSW, MetadataIndexManager) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/graph/graphAdjacencyIndex.ts | 149 +++++++-- src/import/BackgroundDeduplicator.ts | 439 +++++++++++++++++++++++++++ src/import/ImportCoordinator.ts | 72 ++--- src/import/index.ts | 5 + src/storage/baseStorage.ts | 255 +++++++++------- 5 files changed, 743 insertions(+), 177 deletions(-) create mode 100644 src/import/BackgroundDeduplicator.ts diff --git a/src/graph/graphAdjacencyIndex.ts b/src/graph/graphAdjacencyIndex.ts index 876f6cf0..7221a68f 100644 --- a/src/graph/graphAdjacencyIndex.ts +++ b/src/graph/graphAdjacencyIndex.ts @@ -41,8 +41,14 @@ export class GraphAdjacencyIndex { private lsmTreeSource: LSMTree // sourceId -> targetIds (outgoing edges) private lsmTreeTarget: LSMTree // targetId -> sourceIds (incoming edges) -
