>
> The {{Dispatcher}} should have a {{SerializableExecutionGraphStore}} which it
> can use to store completed jobs. This store can then be used to serve
> historic job requests from the web UI, for example. The default
> implementation should persist the jobs to disk and evict the in memory
> instances once they grow to big in order to avoid memory leaks. Additionally,
> the store should expire elements from disk after a user defined time.
