  • Smaller ids (64-bit?)

Effects

  • + Capacity
    • Strictly necessary for this reason alone
  • + Throughput/Latency
    • + Avoid hot spots
    • Multiple hosts can service requests in parallel
    • Do either of these matter if nodes can handle 1M requests/sec?
  • - Throughput/Latency
    • Cost to map address -> shard, shard -> host on client

  • - Consistency
  • - Reliability
