From 1b265e8c42be6b329b065953b5e81f9117f2bc8a Mon Sep 17 00:00:00 2001 From: David Snelling Date: Thu, 7 Aug 2025 11:46:07 -0700 Subject: [PATCH] feat(storage): fix critical socket exhaustion during metadata reading MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CRITICAL ISSUE FIXED: Service initialization was failing due to socket exhaustion when reading metadata for 1400+ items during index rebuild Changes: - Add batch metadata reading to prevent 2000+ concurrent requests - Implement strict concurrency control (3 max concurrent requests) - Add proper yielding between batches to prevent event loop blocking - Reduce batch sizes during initialization (50 โ†’ 25 items per batch) - Add getMetadataBatch() and getVerbMetadataBatch() methods to S3 storage - Update StorageAdapter interface with batch methods - Add production environment auto-detection for smart logging - Auto-cleanup legacy /index folder during initialization Socket usage: Reduced from 1400+ concurrent to 3 max concurrent Expected production result: - Service initialization will complete successfully - firehoseServiceInitialized: true - Data collection will begin normally - No more socket exhaustion errors (100 socket limit exceeded) Fixes: #socket-exhaustion Breaking: None - backward compatible with fallback modes --- src/brainyData.ts | 25 +-- src/coreTypes.ts | 7 + src/storage/adapters/s3CompatibleStorage.ts | 178 ++++++++++++++++++-- src/utils/environment.ts | 100 +++++++++++ src/utils/logger.ts | 107 +++++++++++- src/utils/metadataIndex.ts | 119 ++++++++++--- src/utils/workerUtils.ts | 1 + 7 files changed, 485 insertions(+), 52 deletions(-) diff --git a/src/brainyData.ts b/src/brainyData.ts index 078cef12..ee03133c 100644 --- a/src/brainyData.ts +++ b/src/brainyData.ts @@ -47,6 +47,7 @@ import { import { IntelligentVerbScoring } from './augmentations/intelligentVerbScoring.js' import { BrainyDataInterface } from './types/brainyDataInterface.js' import { augmentationPipeline } from './augmentationPipeline.js' +import { prodLog } from './utils/logger.js' import { prepareJsonForVectorization, extractFieldFromJson @@ -683,7 +684,7 @@ export class BrainyData implements BrainyDataInterface { } if (this.loggingConfig?.verbose) { -
