Don't Let RPCs Constrain Your API

Abstract

As 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.
