From 65703dbe59d6ef893985b7e96bce23016abc8274 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Tue, 6 Jan 2026 16:02:13 -0800 Subject: [PATCH] fix: resolve 50-100x slower add() on cloud storage (GCS/S3/R2/Azure) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause: Storage type detection at setupIndex() relied on this.config.storage.type which was never set after createStorage() auto-detected the storage type. This caused cloud storage to use 'immediate' persistence mode instead of 'deferred', resulting in 20-30 GCS writes per add() operation (7-12 seconds instead of 50-200ms). Fix: Added getStorageType() helper that detects storage type from the storage instance class name (e.g., GcsStorage → 'gcs'), used as fallback when config.storage.type is not explicitly set. Also added: - Performance regression tests (10 new tests) - test:perf npm script for running performance tests 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- package.json | 1 + src/brainy.ts | 34 ++- .../unit/performance/add-performance.test.ts | 213 ++++++++++++++++++ 3 files changed, 246 insertions(+), 2 deletions(-) create mode 100644 tests/unit/performance/add-performance.test.ts diff --git a/package.json b/package.json index ebef25a9..24caa828 100644 --- a/package.json +++ b/package.json @@ -83,6 +83,7 @@ "test:watch": "NODE_OPTIONS='--max-old-space-size=8192' vitest --config tests/configs/vitest.unit.config.ts", "test:coverage": "NODE_OPTIONS='--max-old-space-size=8192' vitest run --config tests/configs/vitest.unit.config.ts --coverage", "test:unit": "NODE_OPTIONS='--max-old-space-size=8192' vitest run --config tests/configs/vitest.unit.config.ts", + "test:perf": "vitest run tests/unit/performance --reporter=basic", "test:integration": "NODE_OPTIONS='--max-old-space-size=32768' vitest run --config tests/configs/vitest.integration.config.ts", "test:s3": "vitest run tests/integration/s3-storage.test.ts", "test:distributed": "vitest run tests/integration/distributed.test.ts", diff --git a/src/brainy.ts b/src/brainy.ts index 31bc9084..16be6a3e 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -5276,6 +5276,31 @@ export class Brainy implements BrainyInterface { return storage as BaseStorage } + /** + * Detect storage type from the storage instance class name + * + * v7.1.1: Fixes storage type detection for HNSW persistence mode. + * Previously relied on this.config.storage.type which was often not set + * after storage creation, causing cloud storage to use 'immediate' mode + * and resulting in 50-100x slower add() operations. + * + * @returns Storage type string ('gcs', 's3', 'memory', etc.) + */ + private getStorageType(): string { + if (!this.storage) return 'memory' + + const className = this.storage.constructor.name + if (className.includes('Gcs') || className.includes('GCS')) return 'gcs' + if (className.includes('S3')) return 's3' + if (className.includes('R2')) return 'r2' + if (className.includes('Azure')) return 'azure' + if (className.includes('OPFS')) return 'opfs' + if (className.includes('FileSystem')) return 'filesystem' + if (className.includes('Memory')) return 'memory' + + return 'unknown' + } + /** * Setup index * @@ -5295,11 +5320,15 @@ export class Brainy implements BrainyInterface { } // v6.2.8: Determine persist mode (user config > smart default) + // v7.1.1: Fixed to use getStorageType() for reliable detection let persistMode: 'immediate' | 'deferred' = this.config.hnswPersistMode || 'immediate' // Smart default: Use deferred mode for cloud storage adapters if (!this.config.hnswPersistMode) { -
