.. _core-api-index: 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: - :class:`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. - :func:`edge_generator ` - A decorator that validates the input arguments of a function and converts them into a dataframe. - :class:`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. - :class:`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. - :func:`node_generator ` - A decorator that validates the input arguments of a function and converts them into a dataframe. - :class:`ParquetGraphDB ` - 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). .. toctree:: :maxdepth: 2 node_store node_generator edge_store edge_generator generator_store parquet_graphdb
