sqlalchemy-mongobi

MongoDB connector for BI SQLAlchemy dialect.

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
