This updates the AdapterCacheRedis instance to be able to handle updating itself when reading from the cache. For this to work we need to pass a `fetchData` function to the `get` method. In the case of a cache miss, we will read the data via the `fetchData` function, and store it in the cache, before returning the value to the caller. When coupled with a `refreshAheadFactor` config, we will go a step further and implement the "Refresh Ahead" caching strategy. What this means is that we will refresh the contents of the cache in the background, this happens on a cache read and only once the data in the cache has only a certain percentage of the TTL left, which is set as a decimal value between 0 and 1. e.g. ttl = 100s refreshAheadFactor = 0.2; Any read from the cache that happens _after_ 80s will do a background refresh |
