>> can't MutablePointValues behave like a single-leaf PointValues instance? There is some friction there. First, in theory we should have the min/max point value for that leaf which currently don't always have (we are throwing a UnsupportedOperationException() ). Another issue is that strictly we are not complying with the PointValues contract that says that for 1D case, we should emit values in a specific order which is not true for MutablePointValues. Finally what happen if the number of points in bigger than Integer.MAX_VALUE? MaxPointPerLeafNode is an integer so we will have trouble representing such structure. I have tried that approach, trying to make MutablePointValues / PointValues with different segments look like a one leaf tree and my feeling is that it makes things much harder, but indeed this patch proposes to add a new abstraction but I was hoping it would reflect better the data structures we are using. -- This is an automated message from the Apache Git Service.
