@lgo Thanks for your contribution, I have applied this patch to our internal version and get a better rescale performance . In my test, the cost of `deleteRange` only at `ms` level . After we introduce the `deleteRange` api, I think we should tune the `OVERLAP_FRACTION_THRESHOLD` for the initial handle. The current default value is `0.75` is somehow conservative . With the fast `deleteRange` we can choose at least an initial handle . By this we can reduce the cost to `iterator` for one fragmented DB. -- This is an automated message from the Apache Git Service.
