I have a period over period block that makes use of a fair amount of Liquid syntax to cut down on the amount of rendered SQL. It occured to me that I don’t know if dimensions that are not used, still execute their Liquid syntax. If so, it would make sense for me to add something like
{% if period_value == '3' %}
around all of them so they don’t execute. Probably doesn’t make a huge difference in execution time, but I would prefer to be as efficient as possible.
