On the Recovery of R-Trees

IEEE Transactions on Knowledge and Data Engineering, 2013
We consider the recoverability of traditional R-tree index structures under concurrent updating transactions, an important issue that is neglected or treated inadequately in many proposals of R-tree concurrency control. We present two solutions to ARIES-based recovery of transactions on R-trees.

Hilbert R-tree: An Improved R-tree using Fractals [PDF]

, 2018
We propose a new R-tree structure that outperforms all the older ones. The heart of the idea is to facilitate the deferred splitting approach in R-trees. This is done by proposing an ordering on the R-tree nodes. This ordering has to be `good', in the sense that it should group `similar' data rectangles together, to minimize the area and perimeter of ...
