Class StorageMetricsStore

  • @ApplicationScoped
public class StorageMetricsStore
extends Object
    This class provides a set of per-tenant counters. Counters such as "number of artifacts" This counters have to be "distributed" or at least work in a clustered deployment. Currently this implementation uses CheckPeriodCache for storing the counters, it's "auto-eviction" nature allows to re-initialize the counters with information from the database periodically, making it "useful" for clustered deployments. This implementation is far from perfect, ideally redis or some other externalized cache should be used, but for now this implementation could work, it's extremely simple and it does not require the deployment of external infrastructure.
