Add detailed documentation explaining Brainy's 4-index architecture:
- MetadataIndex: inverted indexing with temporal bucketing (v3.41.0)
- HNSWIndex: hierarchical vector similarity search
- GraphAdjacencyIndex: O(1) bidirectional relationship traversal
- DeletedItemsIndex: soft-delete tracking
Includes explanation of UnifiedCache for coordinated memory management
across all indexes, integration patterns, performance characteristics,
and best practices for developers.
Updated overview.md to reference the new index architecture documentation.
Critical fix for GCS/S3 native storage adapters crashing on metadata index keys.
Problem:
- GCS and S3 adapters crashed with "Invalid UUID format" errors
- System keys like __metadata_field_index__status are NOT UUIDs
- Adapters incorrectly tried to shard all metadata keys as UUIDs
Solution:
- Move sharding/routing logic from adapters to BaseStorage class
- Add analyzeKey() method to detect system keys vs entity UUIDs
- System keys route to _system/ directory (no sharding)
- Entity UUIDs route to sharded directories (256 shards)
- All adapters now implement 4 primitive operations:
* writeObjectToPath(path, data)
* readObjectFromPath(path)
* deleteObjectFromPath(path)
* listObjectsUnderPath(prefix)
Benefits:
- Impossible for future adapters to repeat this mistake
- Zero breaking changes, full backward compatibility
- No data migration required
- Cleaner architecture with better separation of concerns
Updated adapters: GcsStorage, S3CompatibleStorage, OPFSStorage,
FileSystemStorage, MemoryStorage
Added: docs/architecture/data-storage-architecture.md
Updated: README.md with architecture docs link
- Removed ImportManager class and exports (use brain.import() instead)
- Fixed all documentation: getStatistics() → getStats()
- Updated 41 files across codebase for consistency
- Removed ImportManager section from API docs
- Added v3.30.0 migration guide to CHANGELOG
Co-Authored-By: Claude <noreply@anthropic.com>
Improve documentation to explicitly show that:
- type: 'gcs' requires gcsStorage config (S3-compatible, HMAC)
- type: 'gcs-native' requires gcsNativeStorage config (native SDK, ADC)
- Mixing type and config objects will fall back to memory storage
- Auto-detection works when type is omitted
Added 'Common Mistakes' section with examples of incorrect usage.
Enhanced migration guide with step-by-step instructions.
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.
Previously, clusterByDomain() and clusterByTime() methods contained
stub implementations that always returned empty arrays. This caused
empty results when attempting domain-based or temporal clustering.
Changes:
- Implement _getItemsByField() to query brain storage
- Implement _getItemsByTimeWindow() to filter by time windows
- Fix _groupByDomain() to check root, metadata, and data fields
- Implement _findCrossDomainMembers() for cross-domain analysis
- Implement _findCrossDomainClusters() to merge similar clusters
- Add comprehensive tests for domain and time clustering
- Update documentation structure to include VFS guides
The methods now properly query the brain's storage, filter results,
and return functional clustering data.
Fixed bug where getMetadataBatch() was reading from wrong directory:
- FileSystemStorage: Changed to use getNounMetadata() instead of getMetadata()
- OPFSStorage: Changed to use getNounMetadata() instead of getMetadata()
- MetadataIndex fallback: Fixed to use getNounMetadata()
- Added getNounMetadata() to StorageAdapter interface
This resolves 0% success rate during metadata index rebuild.
Also added comprehensive API documentation for return values and data field behavior.
