Describe your usage question

Does multitransport support installing multiple transport components simultaneously (e.g., both RDMA and TCP at the same time)? If yes, since each transfer engine only has one segment, how can RDMA and TCP segments coexist? If not, suppose a SubmitTransfer call includes transfer requests for two remote segments—one requiring RDMA and another requiring TCP (but TCP transport is not installed locally). How would this scenario be handled?

We will release the next version of Mooncake Transfer Engine that supports multi-transport in the same batch in 25Q3.
