| # Evaluates a sample of keys/values from each redis database, computing statistics for each key pattern: | |
| # keys: number of keys matching the given pattern | |
| # size: approximation of the associated memory occupied (based on size/length of value) | |
| # percent: the proportion of this 'size' relative to the sample's total | |
