    Description

      It might be worth providing read-only views of tablets on multiple servers, while writes go to a single authoritative server. This could improve query performance in some cases.

      Some things to consider:

      1. Consistency: can I read what I've just written?
      2. Configuration: how many copies?
      3. Configuration: how long between syncs?
      4. Performance: locality, number of file replicas

      Variation:

      Permit multiple hosting only on tables that have been locked for writes (useful with a strictly enforced clone-and-lock feature).
