Constructor Detail

CompactionPlannerInitParams

public CompactionPlannerInitParams(CompactionServiceId serviceId,
                                   Map<String,String> plannerOpts,
                                   ServiceEnvironment senv)

Method Detail

getServiceEnvironment

public ServiceEnvironment getServiceEnvironment()

Specified by:

getServiceEnvironment in interface CompactionPlanner.InitParameters

getOptions

public Map<String,String> getOptions()

Specified by:

getOptions in interface CompactionPlanner.InitParameters

Returns:

The configured options. For example if the system properties tserver.compaction.major.service.s1.planner.opts.p1=abc and tserver.compaction.major.service.s1.planner.opts.p9=123 were set, then this map would contain p1=abc and p9=123. In this example s1 is the identifier for the compaction service. Each compaction service has a single planner.

getFullyQualifiedOption

public String getFullyQualifiedOption(String key)

Specified by:

getFullyQualifiedOption in interface CompactionPlanner.InitParameters

Returns:

For a given key from the map returned by CompactionPlanner.InitParameters.getOptions() determines the fully qualified tablet property for that key. For example if a planner was being initialized for compaction service CS9 and this method were passed prop1 then it would return tserver.compaction.major.service.CS9.planner.opts.prop1.

getExecutorManager

public ExecutorManager getExecutorManager()

Specified by:

getExecutorManager in interface CompactionPlanner.InitParameters

Returns:

an execution manager that can be used to created thread pools within a compaction service.

getRequestedExecutors

public Map<CompactionExecutorId,Integer> getRequestedExecutors()

getRequestedExternalExecutors

public Set<CompactionExecutorId> getRequestedExternalExecutors()
