The cache is based on dates and date intervalls. It can be parameterized to define the size (timeSpan) and the amount of update iterations (updateIntervall).
The cache holds values for the following intervall (2022-03-19 -> 2022-03-26)
- parameter
timeSpan= 5 (days) - parameter
updateIntervall= 10 (days)
This means the cache would be updated every 10 days. Every 10 days the timespan will get reduced so that the oldest entry in the cache is not older than 5 days.
Cache: 2022-03-19, 2022-03-20, 2022-03-21, 2022-03-22, 2022-03-23, 2022-03-24, 2022-03-25, 2022-03-26 (last udpated 2022-03-09)
- The cache gets updated with a value for 2022-03-27 the last updated date of the cache is 2022-03-09
2022-03-27 - 2022-03-09 = 18-> older than 10 days that means the following action will happen:2022-3-27 - 5 days = 2022-3-22-> everything older than2022-3-22will be deleted
New Cache: 2022-03-22, 2022-03-23, 2022-03-24, 2022-03-25, 2022-03-26, 2022-03-27 (last updated 2022-03-27)
