Concurrent Path-Copying Update to Tree Structures

Summary: ConTree enables concurrent, order-preserving path-copying updates for general-purpose trees, beyond Contreap’s augmented BSTs. Its AERT and BeTree instantiations optimize ART and B+Tree snapshotting, delivering scalable updates and substantial speedups over serial designs. (summarized by gpt-5.6-luna on Jul 26 2026)
