Expand description

HummockStateStoreMetrics stores the performance and IO metrics of XXXStore such as RocksDBStateStore and TikvStateStore. In practice, keep in mind that this represents the whole Hummock utilization of a RisingWave instance. More granular utilization of per materialization view job or an executor should be collected by views like StateStats and JobStats.
