MongoDB connector for BI SQLAlchemy Dialect

Project description

MongoDB connector for BI SQLAlchemy dialect.

https://img.shields.io/pypi/v/sqlalchemy_mongobi.svg https://img.shields.io/travis/smarzola/sqlalchemy-mongobi.svg

MongoDB connector for BI does not have support for transactions but SQLAlchemy DBAPI layer uses ROLLBACKs after the connection initialization even if the connection pool is configured with reset_on_return=False. This dialect ignores COMMITs and ROLLBACKs, and uses the NullPool connection pool (which means no pooling, opens and closes the underlying DB-API connection per each connection open/close).

Usage

The DSN format is similar to that of mysql:

engine = create_engine(
    "mongobi://user?source=auth_db:password@url:port/database",
    connect_args={
        "ssl": {
            "mode": "PREFERRED"
        }
    },
    pool_reset_on_return=False,
)

DBAPI Support

The following DBAPI options are available:

  • mysqlclient:

    mongobi+mysqldb://user?source=auth_db:password@url:port/database
    
  • PyMySQL:

    mongobi+pymysql://user?source=auth_db:password@url:port/database
