I am utilizing a funnel view concept. I have joined different metric-sets on the funnel. The performance however is not great. One more obvious way to improve it (for my situation) would be to take the funnel, that serves the base of the explore, and persist the values that are from the day prior and earlier. Once we have that, unioning the current day’s worth of data should be a much smaller deal and can therefore reduce the total time spent creating the PDT for the funnel. Is there any ways that I can union the one PDT that can be run on a nightly update schedule and the other with our current day values for my explore?
