What is the RetainSameConnection property and what is its impact? in SSIS

Whenever a task uses a connection manager to connect to source or destination database, a connection is opened and closed with the execution of that task. Sometimes you might need to open a connection, execute multiple tasks and close it at the end of the execution. This is where RetainSameConnection property of the connection manager might help you. When you set this property to TRUE, the connection will be opened on first time it is used and remain open until execution of the package completes.
