Jet 3.0
  • Method Details

    • hazelcastInstance

      @Nonnull HazelcastInstance hazelcastInstance()
      Returns the current Hazelcast instance.
    • jetInstance

      @Nonnull @Deprecated JetInstance jetInstance()
      Use hazelcastInstance().getJet() instead.
      Returns the current Jet instance.
    • jobId

      long jobId()
      Returns the job ID. Job id is unique for job submission and doesn't change when the job restarts. It's also unique for all running and archived jobs.
    • executionId

      long executionId()
      Returns the job execution ID. It's unique for one execution, but changes when the job restarts.
    • jobConfig

      @Nonnull JobConfig jobConfig()
      Returns the JobConfig.
    • totalParallelism

      int totalParallelism()
      Returns the total number of Processors that will be created across the cluster. This number remains stable for entire job execution. It is equal to memberCount() * localParallelism().
    • localParallelism

      int localParallelism()
      Returns the number of processors that each ProcessorSupplier will be asked to create once deserialized on each member. All members have equal local parallelism. The count doesn't change unless the job restarts.
    • memberCount

      int memberCount()
      Returns the number of members running this job.

      Note that the value might be lower than current member count if members were added after the job started. The count doesn't change unless the job restarts.

    • vertexName

      @Nonnull String vertexName()
      Returns the name of the associated vertex.
    • logger

      @Nonnull ILogger logger()
      Returns a logger for the associated ProcessorMetaSupplier.
    • snapshottingEnabled

      default boolean snapshottingEnabled()
      Returns true, if snapshots will be saved for this job.
    • processingGuarantee

      ProcessingGuarantee processingGuarantee()
      Returns the guarantee for current job.
    • maxProcessorAccumulatedRecords

      long maxProcessorAccumulatedRecords()
      Returns the maximum number of records that can be accumulated by any single Processor. The returned value is strictly positive (>=1).
    • isLightJob

      boolean isLightJob()
      Returns if this job runs as a light job, see JetService.newLightJob(Pipeline).
    • partitionAssignment

      Map<Address,int[]> partitionAssignment()
      Returns the partition assignment used by this job. This is the assignment partitioned edges will use and the assignment processors dealing with Hazelcast data structures should use. Each mapped partitions id array must be sorted.
    • classLoader

      ClassLoader classLoader()
      Processor classloader configured via JobConfig.addCustomClasspath(String, String)
      processor classloader, null if no custom classpath elements are configured
    • dataConnectionService

      DataConnectionService dataConnectionService()
      A service to access DataConnections in processors.
    • checkPermission

      void checkPermission(@Nonnull Permission permission) throws AccessControlException
      Check if the current Subject has the given permission granted (or implied).
      permission - Permission to be checked
      AccessControlException - when the security is enabled and the checked permission is not implied for the current Subject
