Example 25 with ProcessBundleDescriptor

use of org.apache.beam.model.fnexecution.v1.BeamFnApi.ProcessBundleDescriptor in project beam by apache.

the class FnApiControlClientPoolService method getProcessBundleDescriptor.

@Override
public void getProcessBundleDescriptor(BeamFnApi.GetProcessBundleDescriptorRequest request, StreamObserver<BeamFnApi.ProcessBundleDescriptor> responseObserver) {
    String bundleDescriptorId = request.getProcessBundleDescriptorId();
    LOG.info("getProcessBundleDescriptor request with id {}", bundleDescriptorId);
    BeamFnApi.ProcessBundleDescriptor descriptor = processBundleDescriptors.get(bundleDescriptorId);
    if (descriptor == null) {
        String msg = String.format("ProcessBundleDescriptor with id %s not found", bundleDescriptorId);
        responseObserver.onError(new StatusException(Status.NOT_FOUND.withDescription(msg)));
        LOG.error(msg);
    } else {
        responseObserver.onNext(descriptor);
        responseObserver.onCompleted();
    }
