> Fetcher was originally designed to fetch CommandInfo::URIs (e.g., executor
> binary) for executors/tasks. A recent refactor (MESOS-336) added caching
> support to the fetcher. The recent work on filesystem isolation/unified
> containerizer (MESOS-2840) requires Mesos to fetch filesystem images (e.g.,
> APPC/DOCKER images) as well. The natural question is: can we leverage the
> fetcher to fetch those filesystem images (and cache them accordingly)?
> Unfortunately, the existing fetcher interface is tightly coupled with
> CommandInfo::URIs for executors/tasks, making it very hard to be re used to
> fetch/cache filesystem images.
> Another motivation for the refactor is that we want to extend the fetcher to
> support more types of schemes. For instance, we want to support magnet URI to
> enable p2p fetching. This is in fact quite important for operating a large
> cluster (MESOS-3596). The goal here is to allow fetcher to be extended (e.g.,
> using modules) so that operators can add custom fetching support.
> The main design goal here is to decouple artifacts fetching from artifacts
> cache management. We can make artifacts fetching extensible (e.g. to support
> p2p fetching), and solve the cache management part later.
