Blocking call detected by BlockHound in DaprGrpcClient

[yshulzh]

Expected Behavior

Implementation of DaprGrpcClient does not make blocking calls.

Actual Behavior

The DaprGrpcClient class has blocking calls in it. For example:

 @Override
  public Mono<byte[]> getState(String actorType, String actorId, String keyName) {
    return Mono.fromCallable(() -> {
      DaprProtos.GetActorStateRequest req =
          DaprProtos.GetActorStateRequest.newBuilder()
              .setActorType(actorType)
              .setActorId(actorId)
              .setKey(keyName)
              .build();

      ListenableFuture<DaprProtos.GetActorStateResponse> futureResponse = client.getActorState(req);
      return futureResponse.get();
    }).map(r -> r.getData().toByteArray());
  }

Note: there are two DaprGrpcClient classes in the project, blocking calls were fixed in one of them, The one I am talking about is in the io.dapr.actors.runtime package.

Release Note
