FACT-Finder Cache
When the cache is enabled, FACT-Finder caches search results, thereby reducing search time and the load on the system. Under More settings, in the System information menu, you can view the current status using the Cache tab and, if necessary, empty the cache manually.
If the cache is not emptied during the day by importing, manually initiating the emptying of the cache or setting the time-to-live of the individual cache entries accordingly, it will be automatically emptied by FACT-Finder between midnight and 6 a.m.
Some configuration changes require you to clear the cache manually if you want them to take effect immediately.
FACT-Finder signals this with a yellow sing with arrows and an exclamation mark visible below.
If you click on it, FACT-Finder opens a dialog box that informs you that the cache needs to be cleared and also offers an opportunity to empty it and/or perform an import.
Regardless of emptying the entire cache, each cache entry has its own lifetime until it is deleted. There are two strategies for managing the lifetime.
time-to-live
This is the default strategy. Each entry has a fixed lifetime (default= 15 minutes) until it is deleted again.time-to-idle
With this strategy, the lifetime of a cache entry is renewed with each call. Only when an entry has not been called for the set duration is it deleted.The use of delta updates has no effect on the lifetime of existing cache entries.
If a time-to-live strategy of 3 minutes is used, all requests would return the new information no later than 3 minutes after the delta update is sent.
