Hi Yue, Thanks for your feedback!

Do we need to support it ？ Yes. If we want to support MultiGet on existing synchronous access mode, we have to introduce a grouping component akin to the AEC described in FLIP-425[1]. I think such a change would introduce additional complexity to the current synchronous model, and the extent of performance gains remains uncertain. Therefore, I recommend only asynchronous interfaces support "Grouping Remote State Access", which is designed to efficiently minimize latency in accessing remote state storage. > 2.

Note that the multiget in this Flip is an internal interface, not a user-facing interface. > 3. I also agree with XiaoRui's viewpoint.

Yes, we would offer some configurable options that allow users to adjust the behavior of batching and grouping state access (eg. batching size, etc.).
