Also,
since you can do node.getGraphDatabase(), I think we don't need to
pass in the graphdb instance in
new SortedTree( graphDb(), graphDb().createNode(), new IdComparator(),

you talk about type I am assuming that you are referring to an interface that
both (Btree,Rtree) can implement, for the data types I'd like to understand
the use cases first before

At this moment Btree only supports the primitive datatype long, while Rtree
only supports the datatype double. For Btree it makes sense to at least support
strings, floats, doubles and ints too. Use cases for these data types

I have previously used two solutions to deal with multiple types in btrees:
- My first index in 2009 was a btree-like n-dim index using generics to
support int[], long[], float[] and double
on the Btree component that is now in neo4j-graph-collections, so we
can eventually have one implementation that meets a broad variety of needs?

It is technically possible, but it is a somewhat specialized index, not a
normal BTree, so I think you would want both (mine and a classic btree). My
index performs better for certain data patterns
Great... Looking forward to your contributions. Once the port is done, we can

A couple of weeks ago Peter Neubauer set up a repository for in-graph

The RTree in principle should be generalizable, but the current
implementation in neo4j-spatial does make a few assumptions specific to
spatial data, and makes use of spatial envelopes for the tree node bounding
boxes. It is also specific to 2D. We could make a few improvements first,

As to the issue of n-dim doubles, it would be interesting to consider
creating a set of classes of type Orderable (supporting , =, , =
operations), this we can use in both Rtree and Btree. Right now Btree only
supports datatype Long. This should also become
