Example 1 with FlushDatasetOperatorDescriptor

use of org.apache.asterix.runtime.operators.std.FlushDatasetOperatorDescriptor in project asterixdb by apache.

the class FlushDatasetUtil method flushDataset.

public static void flushDataset(IHyracksClientConnection hcc, MetadataProvider metadataProvider, String dataverseName, String datasetName, String indexName) throws Exception {
    CompilerProperties compilerProperties = metadataProvider.getApplicationContext().getCompilerProperties();
    int frameSize = compilerProperties.getFrameSize();
    JobSpecification spec = new JobSpecification(frameSize);
    RecordDescriptor[] rDescs = new RecordDescriptor[] { new RecordDescriptor(new ISerializerDeserializer[] {}) };
    AlgebricksMetaOperatorDescriptor emptySource = new AlgebricksMetaOperatorDescriptor(spec, 0, 1, new IPushRuntimeFactory[] { new EmptyTupleSourceRuntimeFactory() }, rDescs);
    org.apache.asterix.common.transactions.JobId jobId = JobIdFactory.generateJobId();
    Dataset dataset = metadataProvider.findDataset(dataverseName, datasetName);
    FlushDatasetOperatorDescriptor flushOperator = new FlushDatasetOperatorDescriptor(spec, jobId, dataset.getDatasetId());
    spec.connect(new OneToOneConnectorDescriptor(spec), emptySource, 0, flushOperator, 0);
    Pair<IFileSplitProvider, AlgebricksPartitionConstraint> primarySplitsAndConstraint = metadataProvider.getSplitProviderAndConstraints(dataset, indexName);
    AlgebricksPartitionConstraint primaryPartitionConstraint = primarySplitsAndConstraint.second;
    AlgebricksPartitionConstraintHelper.setPartitionConstraintInJobSpec(spec, emptySource, primaryPartitionConstraint);
    JobEventListenerFactory jobEventListenerFactory = new JobEventListenerFactory(jobId, true);
    spec.setJobletEventListenerFactory(jobEventListenerFactory);
