 - The memory requirement of `logreplay` operation mode without preload isn't deterministic and depends on the columnstore structures loaded. In extreme cases, you might require 50% of the memory of the primary instance. The memory for `logreplay` operation mode is independent on whether you chose to have the data preloaded set or not.
