FPTree: A Hybrid SCM-DRAM Persistent and Concurrent B-Tree for Storage Class Memory
Summary: FPTree is a hybrid SCM-DRAM persistent B+-Tree with leaves in SCM and inner nodes in DRAM (rebuilt on recovery). It uses fingerprinting to cap in-leaf probes and a partial HTM-based concurrency scheme, delivering up to 8.2x speedups and 88-core scalability, with memcached/DB integration.
