The most efficient and flexible way to gather and assess time series data in redis combines two different structures: the sorted set and the hash. Every entry in a sorted set is a combination of a double “score” and a string “member,” with the former acting as the sorted value in the tree and the latter acting as a key in the hash.
We can similarly extract more granular features if we have the time stamp. For instance, we can determine the hour or minute of the day when the data was recorded and compare the trends between the business hours and non-business hours.
