Hi there, starting just following up what we've discussed in the demo meeting The two use-cases I was talking about: 1) I'm fetching daily data from Global Forecast server since 2021-01-01. To do that, I use just one multi-paritioned asset with two keys. the second key assuming 81 values. That said, I would have to materialize ~56K (no 48, my mistake kkk) assets, which I suppose I could do by batches. 2) That is not my current problem, but another IoT common situation is having to mine a bunch of devices (let us pick 100, for example), each one having a bunch of operating signals, like temperatures, current, voltages, etc (50 signals). One could want to mine all this data and stream some calculation, what would yield 5K materializations

@owen - should you want to pick up the thread!

In fact, that run_coordinator totally solved this issue
