Method Details

getImmutablePlanByKey

@Nullable
public @Nullable ImmutableChain getImmutablePlanByKey(@NotNull
 @NotNull PlanKey planKey)

Description copied from interface: ImmutablePlanCacheService

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.

Specified by:

getImmutablePlanByKey in interface ImmutablePlanCacheService

• ImmutablePlanCacheService.withHiddenPlans(Collection, Supplier)

getImmutablePlanByKeyWithConsistencyGuarantee

@Nullable
public @Nullable ImmutableChain getImmutablePlanByKeyWithConsistencyGuarantee(@NotNull
 @NotNull PlanKey planKey)

Description copied from interface: ImmutablePlanCacheService

public @NotNull Stream<ImmutableChain> getImmutablePlansByKeysWithConsistencyGuarantee(@NotNull
 @NotNull Collection<PlanKey> planKeys,

getImmutablePlansByKeysWithConsistencyGuarantee

@NotNull
public @NotNull Stream<ImmutableChain> getImmutablePlansByKeysWithConsistencyGuarantee(@NotNull
 @NotNull Collection<PlanKey> planKeys,
 boolean onlyLoaded,
 @NotNull
 @NotNull Collection<PlanKey> whiteListedPlans)

Description copied from interface: ImmutablePlanCacheService

Returns a stream of found plans for requested plan keys. There are no nulls in the stream. There is a guarantee that the data will be up-to-date. If BambooClusterSettings.isOptimisticLockingEnabled() is disabled, then no consistency is made.

Specified by:

getImmutablePlansByKeysWithConsistencyGuarantee in interface ImmutablePlanCacheService

Parameters:

planKeys - the plan keys to retrieve data for

onlyLoaded - determines if keys not found in the cache will be loaded (false) or not (true)

whiteListedPlans - the plans that are already considered up-to-date, i.e., they are already highly-consistent and no check will be made if they are found in the cache.

Returns:

the plans found in the cache and, if onlyLoaded=false, the eventual ones that were loaded.
