@lidavidm I'm investigating both ArrowFlight and Plasma-like plans. For plasma-like plan, I may do this like: 1. Setup a grpc service in our storage server. 2. Client calls InternalScan interface to server. 3. Server will create an arrow record batch for response and store it into shared memory. (maybe zero-copy or one-copy) 4. Client get the reference of recordbatch from InternalScanResponse, and to recover this record batch with zero-copy BTW: If we use native plasma-store, one-copy is ineluctable, so we may borrow some ideas from plasma store. For ArrowFlight: We can not avoid the data copy and transfer in unix domain socket. I'm not sure the performance requirement of user, so I need to do some more investigates. -- This is an automated message from the Apache Git Service.
