Implements client-side encryption for vector embeddings before transmission to a remote database, using symmetric encryption (likely AES-256-GCM or similar) with key management handled entirely on the client. Vectors are encrypted at rest and in transit, with decryption occurring only after retrieval on the client side. This architecture ensures the database server never has access to plaintext vectors or their semantic content, enabling privacy-preserving similarity search without trusting the backend infrastructure.
Unique: Implements client-side encryption for vector embeddings with transparent key management in TypeScript, enabling encrypted similarity search without exposing vector semantics to the database server — a rare architectural pattern in vector database clients that typically assume trusted infrastructure
vs alternatives: Provides stronger privacy guarantees than Pinecone or Weaviate's native encryption (which encrypt at rest but expose vectors to the server during queries) by ensuring the server never handles plaintext vectors, though at the cost of client-side computational overhead
Executes similarity search queries against encrypted vector embeddings using approximate nearest neighbor (ANN) algorithms, likely implementing locality-sensitive hashing (LSH), product quantization, or HNSW-compatible approaches adapted for encrypted data. The client constructs encrypted query vectors and retrieves candidate results from the backend, then decrypts and re-ranks results locally to ensure accuracy despite the encryption layer. This enables semantic search without the server inferring query intent.
Unique: Adapts approximate nearest neighbor search algorithms to work with encrypted vectors by performing server-side ANN on ciphertext and client-side re-ranking on decrypted results, maintaining privacy while leveraging ANN efficiency — most vector databases either skip ANN for encrypted data or don't support encryption at all
vs alternatives: Enables semantic search with stronger privacy than Weaviate's encrypted search (which still exposes vectors during query processing) while maintaining better performance than fully homomorphic encryption approaches that are computationally prohibitive
Validates vector dimensions against expected embedding model output sizes and checks compatibility between query vectors and stored vectors before operations, preventing dimension mismatches that would cause silent failures or incorrect results. The implementation likely maintains a registry of common embedding models (OpenAI, Anthropic, Sentence Transformers) with their output dimensions, validates vectors at insertion and query time, and provides helpful error messages when mismatches occur.
Unique: Implements proactive dimension validation with embedding model compatibility checking, preventing silent failures from dimension mismatches — most vector clients lack this validation, allowing incorrect operations to proceed
vs alternatives: Catches dimension mismatches at operation time rather than discovering them through incorrect search results, providing better developer experience than manual dimension tracking
Deduplicates vector search results based on vector ID or metadata fields, and re-ranks results by relevance score or custom ranking functions after decryption. The implementation likely supports multiple deduplication strategies (exact match, fuzzy match on metadata), custom ranking functions (e.g., boost recent documents), and result normalization (score scaling, percentile ranking). This enables sophisticated result presentation without exposing ranking logic to the server.
Unique: Implements client-side result deduplication and custom ranking for encrypted vector search, enabling sophisticated result presentation without exposing ranking logic to the server — most vector databases lack built-in deduplication and ranking
vs alternatives: Provides more flexible result ranking than server-side ranking (which is limited by what the server can see) while maintaining privacy by keeping ranking logic on the client
Provides a client-side key management abstraction that handles encryption key generation, storage, rotation, and versioning for vector data. The implementation likely supports multiple key derivation strategies (PBKDF2, Argon2, or direct key material) and maintains key version metadata to support rotating keys without re-encrypting all historical vectors. Keys can be sourced from environment variables, key management services (AWS KMS, Azure Key Vault), or derived from user credentials.
Unique: Implements client-side key versioning and rotation for encrypted vectors without requiring server-side key management, allowing users to rotate keys independently while maintaining backward compatibility with older encrypted vectors — a critical feature for long-lived vector databases that most encrypted vector clients omit
vs alternatives: Provides more flexible key management than database-native encryption (which typically requires server-side key rotation) while remaining simpler than full KMS integration, making it suitable for teams with moderate compliance requirements
Provides a strongly-typed TypeScript API for vector database operations, with full type inference for vector payloads, metadata schemas, and query results. The implementation likely uses generics to allow users to define custom metadata types, with compile-time validation of metadata field access and query filters. This enables IDE autocomplete, compile-time error detection, and self-documenting code for vector operations.
Unique: Implements a generic TypeScript API for vector operations with compile-time metadata schema validation, allowing users to define custom types for vector metadata and catch schema mismatches before runtime — most vector clients (Pinecone, Weaviate SDKs) provide minimal type safety for metadata
vs alternatives: Offers stronger type safety than Pinecone's TypeScript SDK (which uses loose metadata typing) while remaining simpler than full schema validation frameworks, making it ideal for teams seeking a middle ground between flexibility and safety
Supports bulk insertion and upsert operations for multiple encrypted vectors in a single API call, with client-side batching and encryption applied to all vectors before transmission. The implementation likely chunks large batches to respect network and memory constraints, applies encryption in parallel using Web Workers or Node.js worker threads, and handles partial failures gracefully with detailed error reporting per vector. This enables efficient bulk loading of vector stores while maintaining end-to-end encryption.
Unique: Implements parallel client-side encryption for batch vector operations using worker threads, with intelligent batching and partial failure handling — most vector clients encrypt vectors sequentially, making bulk operations significantly slower
vs alternatives: Achieves 3-5x higher throughput for bulk vector insertion than sequential encryption approaches while maintaining end-to-end encryption guarantees, though still slower than plaintext bulk operations due to encryption overhead
Applies metadata-based filtering to vector search results after decryption on the client side, supporting complex filter expressions (AND, OR, NOT, range queries, string matching) without exposing filter logic to the server. The implementation likely parses filter expressions into an AST, evaluates them against decrypted metadata objects, and returns only results matching all filter criteria. This enables privacy-preserving filtered search where the server cannot infer filtering intent.
Unique: Implements client-side metadata filtering with complex boolean logic evaluation, ensuring filter criteria remain hidden from the server while supporting rich query expressiveness — most encrypted vector systems either lack filtering entirely or require server-side filtering that exposes filter intent
vs alternatives: Provides stronger privacy for filtered queries than Weaviate's encrypted search (which still exposes filter logic to the server) while remaining more flexible than simple equality-based filtering
