Does the WriteAPI client support context management? If so what does the context manager do - flush, close, wait for batch to complete? I cannot answer any of these queststions reading the doucmentation so I don't know if I should be creating a new instance of WriteApi client evey time I want to write a new batch..

Important: The WriteApi in batching mode (default mode) is suppose to run as a singleton. To flush all your data you should call _write_client.close() at the end of your script.

This part of the documentation I find contradictory - singleton implies never create another instance - but it goes on to say I should close to flush?? What if I have a service continuously running? How can I flush what has already been written if I want to? I don't feel confident reading the documentation using this library...
