Stores memories as nodes in a directed graph structure with domain-driven design principles, enabling relationships between memory entities to be explicitly modeled and traversed. Uses embedding vectors to index memory content semantically, allowing memories to be retrieved not just by exact match but by conceptual similarity. The graph structure persists relationships between domain entities (e.g., users, conversations, events) as first-class citizens rather than denormalized fields.
Unique: Implements domain-driven design patterns (aggregates, value objects, bounded contexts) as first-class concepts in the memory layer, allowing developers to define domain models that automatically structure the graph topology rather than forcing a generic key-value or document model
vs alternatives: Differs from vector-only RAG systems (Pinecone, Weaviate) by explicitly modeling entity relationships as graph edges, enabling reasoning over connected entities rather than just similarity-ranked documents
Implements vector similarity search by computing embeddings for memory queries and comparing them against stored memory embeddings using distance metrics (cosine, Euclidean). Returns ranked results ordered by semantic relevance rather than keyword overlap. Supports configurable embedding models and distance functions, allowing swapping between different embedding providers without changing query logic.
Unique: Integrates embedding computation and similarity search as a core abstraction within the domain model layer, allowing domain entities to define custom embedding strategies (e.g., embedding only certain fields, combining multiple embeddings) rather than treating embeddings as a separate indexing concern
vs alternatives: More flexible than specialized vector databases (Pinecone, Weaviate) for small-to-medium deployments because it allows embedding model swapping and custom distance metrics without vendor lock-in, though it lacks the distributed scale and query optimization of dedicated vector DBs
Provides an abstraction layer for memory persistence that decouples the domain model from storage implementation. Developers can implement custom storage adapters (file-based, database, cloud storage) by conforming to a standard interface, enabling memories to be persisted to any backend without changing application code. Supports both synchronous and asynchronous persistence operations.
Unique: Uses adapter pattern at the domain layer rather than the infrastructure layer, allowing domain aggregates to define persistence requirements (e.g., 'this memory must be encrypted') that adapters must satisfy, rather than treating persistence as a generic concern
vs alternatives: More flexible than ORMs (TypeORM, Sequelize) for memory-specific workloads because it doesn't assume relational schemas and allows custom serialization logic, though it requires more manual adapter implementation than full-featured ORMs
Allows defining typed relationships between memory entities (e.g., 'mentions', 'references', 'contradicts') and traversing the graph to discover connected memories. Relationships are first-class objects with properties, enabling rich semantic connections beyond simple foreign keys. Supports depth-limited traversal, filtering by relationship type, and aggregating results across multiple paths.
Unique: Models relationships as domain aggregates with properties and behavior, rather than simple edges, enabling relationship-specific logic (e.g., a 'contradicts' relationship can compute contradiction strength) and relationship versioning
vs alternatives: Richer than simple document references (MongoDB, Firestore) because relationships are typed and queryable; simpler than dedicated graph databases (Neo4j) for small-to-medium graphs and doesn't require a separate database system
Tracks memory creation, modification, and access timestamps, enabling time-based queries and memory aging strategies. Supports marking memories as archived, deleted, or expired, and provides hooks for lifecycle events (on-create, on-update, on-access). Enables implementing memory decay (older memories ranked lower) and retention policies without manual cleanup.
Unique: Integrates temporal tracking as a domain concern rather than a storage concern, allowing domain aggregates to define custom decay functions and lifecycle policies that are independent of the storage backend
vs alternatives: More flexible than TTL-based expiration (Redis, DynamoDB) because it supports custom decay functions and lifecycle hooks; simpler than time-series databases (InfluxDB, TimescaleDB) for memory-specific workloads
Provides a framework for defining domain models (entities, value objects, aggregates) with type safety, enabling developers to structure memories according to domain concepts rather than generic key-value pairs. Supports validation, serialization, and custom methods on domain objects. Type definitions enable IDE autocomplete and compile-time checking for memory operations.
Unique: Implements domain-driven design at the type level, allowing domain models to be defined as classes with methods and validation logic, rather than as separate schema definitions, enabling domain logic to live with domain data
vs alternatives: More expressive than JSON Schema for domain modeling because it supports methods and inheritance; more flexible than ORMs (TypeORM) because it doesn't assume relational structure
Supports performing multiple memory operations (create, update, delete, relate) as a logical unit with rollback on failure. Implements optimistic concurrency control or pessimistic locking depending on configuration. Enables efficient bulk operations without individual round-trips to storage, useful for syncing large memory sets or performing complex multi-step memory updates.
Unique: Implements transaction semantics at the domain layer rather than delegating to storage, allowing domain-specific rollback logic (e.g., cascading deletes, relationship cleanup) that adapters don't need to understand
vs alternatives: Simpler than distributed transactions (Saga pattern) for single-instance deployments; more flexible than database transactions because it can span multiple storage adapters
Provides a query API for filtering memories by properties, relationships, and temporal criteria, with support for aggregation operations (count, group-by, statistics). Queries are composable and can be combined with semantic search. Supports both simple property filters and complex nested queries on related entities.
Unique: Integrates structured filtering with semantic search in a single query API, allowing developers to combine property filters with similarity scores without separate query paths
vs alternatives: More flexible than document database queries (MongoDB) for memory-specific workloads because it understands domain relationships; simpler than SQL for non-relational memory structures

vs alternatives: More flexible than static schema definitions because it reflects live database state, including recent migrations or schema changes
Enforces Supabase Row-Level Security policies within agent queries, ensuring that agents can only access rows permitted by RLS rules defined in the database. Evaluates policies based on authenticated user context (JWT claims, user ID) and applies WHERE clause filters automatically, preventing unauthorized data access at the database layer rather than application layer.
Unique: Delegates authorization enforcement to PostgreSQL RLS policies rather than implementing authorization in agent code, ensuring that data access rules are centralized and cannot be bypassed by agent logic
vs alternatives: More secure than application-level authorization because RLS is enforced at the database layer, preventing accidental data leaks even if agent code has bugs
