> Even though RegionStates is a highly accessed data structure in HMaster. Most of it's methods are synchronized. Which limits concurrency. Even simply making some of the getters non-synchronized by using concurrent data structures has helped with region assignments. We can go as simple as this approach or create locks per region or a bucket lock per region bucket.
