Interface ImmutablePlanCacheService

  • All Known Implementing Classes:
    ImmutablePlanCacheServiceImpl
    @Internal
public interface ImmutablePlanCacheService
    An experimental API for getting immutable, weakly held, cached ImmutableChain. This Service does not check for permissions currently. Only works for Chain. Cache is disabled by default and should be explicitly enabled by application (preferably by calling initialiseCache())
    Concepts:
    cache invalidation
    Temporary removal of plan from cache (ie as an effect of changed plan configuration). Cache invalidation will remove Plan from cache but will not remove metadata information (ie planKey->id mapping)
    cache reset
    Permament removal of plan from cache (ie as an effect of plan deletion or move to another project). Cache reset will remove Plan and all related data from the cache.
    This class is for internal use only, you should probably be using CachedPlanManager instead. If the method does not contain `...WithConsistencyGuarantee` in its name, then it does not guarantee that the data is up-to-date a.k.a. highly consistent in the cluster mode.
    Since:
    v3.4

      • getImmutablePlanByKey

        @Nullable
@Nullable ImmutableChain getImmutablePlanByKey​(@NotNull
                                               @NotNull PlanKey planKey)
        Returns a plan if one exists with the key. Returns null if the plan doesn't exist or if the cache entry is currently inaccessible because it is locked by another caller. In clustered mode, there is NO consistency guarantee.
