Package btree/plus implements the ubiquitous B+ tree. As of this writing, the tree is not quite finished. The delete-node merge functionaly needs to be added. There are also some performance improvements that can be made, with some possible concurrency mechanisms.

This is a mutable b-tree so it is not threadsafe.

Performance characteristics: Space: O(n) Insert: O(log n) Search: O(log n)
