Connection

Core-Lib provides a standard interface to connect to any data source. It offers two base classes for each data source type (Connection and ConnectionRegistry). While keeping the same coding structure and making it easy to support any new data source

Connection

core_lib.connection.connection.Connection [source]

The Connection class is the base class of all connection types. It abstracts the Context Manager 1 __enter__ method to allocate and return the session/client instance and the __exit__ method for releasing resources automatically. The connection class will come to use along the "with" statement.

ConnectionRegistry

core_lib.connection.connection_registry.ConnectionRegistry [source]

ConnectionRegistry is an abstract class that extends the Registry [source] capabilities to provide a Connection instance using the get function, and it’s the base class for all ConnectionRegistry classes.

Built-in Connections

By default, Core-Lib connections support four types of connection.

Database

MongoDB

The MongoDB connection uses PyMongo to provide the MongoDB client instance.

Neo4j

The Neo4j connection uses ne04j-python-driver to provide the Neo4J Session instance.

The SOLR connection uses pysolr to provide the Solr client instance.
