Example 1 with TransferReplyProto

use of org.apache.ratis.proto.ExperimentsProtos.TransferReplyProto in project incubator-ratis by apache.

the class ClientProto method execProto.

public void execProto(int reps) throws Exception {

            // creates a ByteString refrencing buffer data. Avoids Copying.
            // Something similar is missing in flatbuffers.
            TransferMsgProto msg = TransferMsgProto.newBuilder().setPartId(partId).setData(UnsafeByteOperations.unsafeWrap(bf)).build();
            requestObserver.onNext(msg);
            i++;
