  • All Implemented Interfaces:
    org.elasticsearch.action.bulk.BulkProcessor.Listener, Computation

    public class BulkIndexComputation
    extends AbstractComputation
    implements org.elasticsearch.action.bulk.BulkProcessor.Listener

    • Method Detail

      • init

        public void init​(ComputationContext context)
        Description copied from interface: Computation
        Called when the framework has registered the computation successfully. Gives users a first opportunity to schedule timer callbacks and produce records. This method can be called multiple times.
        Specified by:
        init in interface Computation
        Overrides:
        init in class AbstractComputation
        Parameters:
        context - The computation context object provided by the system.
      • processRecord

        public void processRecord​(ComputationContext context,
                                  String inputStream,
                                  Record record)
        Description copied from interface: Computation
        Process an incoming record on one of the computation's input streams.
        Specified by:
        processRecord in interface Computation
        Parameters:
        context - The computation context object provided by the system.
        inputStream - Name of the input stream that provides the record.
        record - The record.
      • destroy

        public void destroy()
        Description copied from interface: Computation
        Called when the framework is ready to shutdown the computation. Gives users a chance to perform some cleanup before the process is killed.
        Specified by:
        destroy in interface Computation
