1. What is Memory versus speed ? Junior A. choosing capacity large enough to hold the actively accessed data without wasting memory on cold entries B. the period of poor hit rates right after startup before a store has accumulated useful entries C. the balance between consuming more RAM to retain entries and accepting slower fetches from the source D. the tension between serving the most current data and minimizing expensive recomputation or fetches
