    Description

      Lazy flag has known issues leading to cluster stability.

      lazy=false can be implemented with certain page size like pageSize==Long.MAX_VALUE.

      To improve stability of the default deployments we must

      • deprecate lazy flag in 2.15
      • make queries lazy by default.
      • remove lazy flag in 2.16
