    Description

      It would be a valuable design improvement to allow for a high/low priority on DCP streams similar to how we handle bucket IO priority.

      Intra-cluster DCP should always be prioritized over anything else to protect against single node failure and especially false-positive autofailover

      Others such as XDCR and views should initially be low priority, with a future improvement to allow for end-user configuration if needed.
