ABSTRACTInterest in recoverable, persistent-memory-resident (PMEM-resident) data structures is growing as availability of Intel Optane Data Center Persistent Memory increases. An interesting use case for inmemory, recoverable data structures is for database indexes, which need high availability and reliability. RECIPE, a popular conversion technique to make existing, proven-correct algorithms recoverable, is limited to certain classes of algorithms and does not prescribe how to reference data stored in relocatable regions of memory. The Untitled Persistent Skip List (UPSkipList) is a PMEM-resident recoverable skip list derived from Herlihy et al.'s lock-free skip list algorithm. It is developed using a new conversion technique that extends the RECIPE algorithm by Lee et al. to work on lock-free algorithms with non-blocking writes and no inherent recovery mechanism. The algorithm is also extended to support concurrent data node splitting to improve performance. Comparison was done against the BzTree of Arulraj et al., as implemented by Lersch et al., which has non-blocking, non-repairing writes implemented using the persistent multi-word CAS (PMwCAS) primitive by Wang et al. Tested with the Yahoo Cloud Serving Benchmark (YCSB), UPSkipList achieves better performance in write-heavy workloads at high levels of concurrency than BzTree, showing that the extension to RECIPE is an effective alternative. |
