> Thanks for opening this PR @Thesharing > I noticed a critical problem of this PR that it assumes the `ConsumedPartitionGroup` can either be consumed all intra-region or inter-region. However, it can happen that a ConsumedPartitionGroup contains both intra-region consumed partition and inter-region one. e.g. A(4) -- pointwise pipelined --> B(3), A(4) -- pointwise pipelined --> C(2), B(3) -- pointwise blocking --> C(2). > I think we need to have a clear idea about how to avoid this case or solve it before we continue with this PR.  -- This is an automated message from the Apache Git Service.
