      Value Statement

      Address:

      1. Historical query from OOTB grafana dashboard times out. We know that this happens when they increase the time range. 
      2. We also know of cases where even at a lower time range the sheer cardinality of metrics creates issues - like a namespace that has 4k pods breaks certain displays.
      3. We find that the compactor crashes or gets stuck - reasons may be different (and that is the goal of this exercise), but this problem does arise when we start accumulating data.
      4. Store PVs keep on increasing in size continuously (and this we have seen even when compactor works)
