Describe your problem

issue:
Status RPCClient::TransferRemoteBlobWithRDMA(std::shared_ptr buffer,
const Payload& payload,
RDMAClient::rdma_opt_t rdma_opt)
When the rdma_opt of TransferRemoteBlobWithRDMA is Read,
RETURN_ON_ERROR(rdma_client_->GetTXCompletion(-1, nullptr)) maybe change to
RETURN_ON_ERROR(rdma_client_->GetRXCompletion(-1, nullptr))

Is so?
