Example 5 with MetadataProvider

use of org.apache.asterix.metadata.declared.MetadataProvider in project asterixdb by apache.

the class CommitPOperator method contributeRuntimeOperator.

@Override
public void contributeRuntimeOperator(IHyracksJobBuilder builder, JobGenContext context, ILogicalOperator op, IOperatorSchema propagatedSchema, IOperatorSchema[] inputSchemas, IOperatorSchema outerPlanSchema) throws AlgebricksException {
    MetadataProvider metadataProvider = (MetadataProvider) context.getMetadataProvider();
    RecordDescriptor recDesc = JobGenHelper.mkRecordDescriptor(context.getTypeEnvironment(op), propagatedSchema, context);
    int[] primaryKeyFields = JobGenHelper.variablesToFieldIndexes(primaryKeyLogicalVars, inputSchemas[0]);
    //get dataset splits
    IPushRuntimeFactory runtime = dataset.getCommitRuntimeFactory(metadataProvider, jobId, primaryKeyFields, isSink);
    builder.contributeMicroOperator(op, runtime, recDesc);
    ILogicalOperator src = op.getInputs().get(0).getValue();
    builder.contributeGraphEdge(src, 0, op, 0);
