Don't Let RPCs Constrain Your API

ABSTRACTAs data becomes increasingly distributed, traditional RPC and data serialization limits performance, result in rigidity, and hamper expressivity. We believe that technology trends including high-density persistent memory, high-speed networks, and programmable switches make this the right time to revisit prior research on distributed shared memory, global addressing, and content-based networking. Our vision combines the code mobility of RPC with first-class data references in a global address space by co-designing the OS and the network around pervasive data identity. We have initial results showing the promise of the proposed co-design.
