Can you help me understand this query execution plan. Especially what is the thickness of the lines indicate? e,g some lines are very thin, some are medium and some are quite thick. I know about the query cost and know that if the cost is more then i need to do something about it, also understand that where to create the indexes as per query plan., but still would be great if you can guide me.
