Hi Casey, All, As mentioned in [1] : "Unfortunately, there is no mechanism to refresh a cache entry in the current experimental version of the fetcher cache."
So in the community there is a need for a maintenance policy to keep the cache up-to-date and I would like to solve this problem as a 1-day hackaton project. So if any of the Mesos Fetcher Cache folks are attending the hackathon I would like to team up with them and solve this problem. In my phd I proposed some optimizations of increasing the freshness of the task outcome when cache data providers apply some restrictions on the number of accesses which is briefly explained here [2]. So after we designed the maintenance policy, we can optimized it for these constraints based accesses using this idea as well.
