Core API¶
The Core API provides the fundamental functionality of MatGraphDB, offering a robust interface for managing a graph database. This module contains the essential classes and methods that enable database-like operations The core components include:
EdgeStore- The main interface class that provides database-like operations over Parquet files. This class handles data storage, retrieval, querying, schema evolution, and complex data type management through an intuitive API that wraps PyArrow’s functionality.edge_generator- A decorator that validates the input arguments of a function and converts them into a dataframe.GeneratorStore- A store for managing generator functions in a graph database. This class handles serialization, storage, and loading of functions that generate edges between nodes.NodeStore- A store for managing node features in a graph database. This class handles data storage, retrieval, querying, schema evolution, and complex data type management through an intuitive API that wraps PyArrow’s functionality.node_generator- A decorator that validates the input arguments of a function and converts them into a dataframe.GraphDB- A manager for a graph storing multiple node types and edge types. Each node type and edge type is backed by a separate ParquetDB instance (wrapped by NodeStore or EdgeStore).
