okay, thanks for the explanation, so from the 3GB of Cache (default cache for SSD) only a 0.5GB is going to K/V and 2.5 going to metadata.
Is there a way of knowing how much k/v, metadata, data is storing and how full cache is so I can adjust my ratios?, I was thinking some ratios (like 0.9 k/v, 0.07 meta 0.03 data) but only speculating, I dont have any real data.
