Fixes critical scalability bottleneck where metadata was stored in non-sharded
directories, causing performance degradation at scale (1M+ entities).
Changes:
- Add UUID-based sharding to metadata operations in S3Compatible, FileSystem, and OpFS storage
- Implement complete UUID-based sharding for OpFS storage (nouns, verbs, metadata)
- Update pagination methods to iterate through all 256 UUID-based shards
- Add integration tests verifying sharding behavior across storage adapters
Impact:
- Metadata now scales to millions of entities without directory bottlenecks
- All storage adapters now use consistent UUID-based sharding (256 buckets: 00-ff)
- Improves GCS/S3/R2/OpFS performance at scale
- Path format: entities/{type}/{subtype}/{shard}/{id}.json
Breaking change: Requires data migration for existing S3/GCS/R2/OpFS deployments.
See .strategy/UNIFIED-UUID-SHARDING.md for migration guidance.
Resolves API accessibility issues reported by Brain Cloud Studio team:
1. Export ImportManager and createImportManager
- ImportManager class was fully implemented but not exported
- Consumers can now access AI-powered import features
- Includes ImportOptions and ImportResult types
2. Add brain.getStats() convenience method
- Documentation showed getStats() as top-level method
- Implementation had it nested under brain.counts.getStats()
- Added convenience method that delegates to counts API
- Maintains backward compatibility
3. Update API documentation
- Corrected getStats() signature and return type
- Added comprehensive ImportManager documentation
- Included examples for all import patterns
These changes expose existing, tested functionality without
modifying core behavior. All tests pass.
Add IntelligentImportAugmentation with support for:
- CSV: auto-detection of encoding, delimiters, and field types
- Excel: multi-sheet extraction with metadata preservation
- PDF: text extraction, table detection, and metadata extraction
Features:
- Automatic format detection from file extension or content
- Intelligent type inference (string, number, boolean, date)
- Seamless integration with neural entity extraction
- Production-ready with 69 comprehensive tests
Dependencies added:
- xlsx@^0.18.5 for Excel parsing
- pdfjs-dist@^4.0.379 for PDF parsing
- csv-parse@^6.1.0 for CSV parsing
- chardet@^2.0.0 for encoding detection
Documentation:
- Updated README with import examples
- Updated API_REFERENCE with comprehensive import() docs
- Updated import-anything.md guide
- Added working example: import-excel-pdf-csv.ts
- Updated augmentations README
- Add @deprecated JSDoc tags to TypeScript definitions
- Update all documentation examples to use modern add() and relate() API
- Preserve batch operations (addNouns, addVerbs) as they remain current
- Mark deprecated methods in both source and compiled definitions
Migration guide:
- addNoun(data, type, metadata) → add(data, { nounType: type, ...metadata })
- addVerb(source, target, type, metadata) → relate(source, target, type, metadata)
- Implement self-configuring validation that adapts to system resources
- Add validation for all CRUD operations (add, update, delete, find, relate)
- Auto-configure limits based on available memory (1GB = 10K limit, 8GB = 80K)
- Monitor and auto-tune performance based on query response times
- Fix multiple type filtering with proper anyOf structure
- Enhance type safety by requiring NounType/VerbType enums
- Fix tests to validate correct behavior (no fake implementations)
- Add comprehensive VALIDATION.md documentation
- Update API_REFERENCE.md with validation rules and examples
- Clarify metadata update behavior (null keeps existing, {} clears)
BREAKING CHANGE: getFieldsForType() now requires NounType enum instead of string
