1. Nonvolatile memory(e.g., Phase Change Memory) blurs the boundary between memory and storage and it could greatly facilitate the construction of in-memory durable data structures. Data structures can be processed and stored directly in NVRAM. To XXX, YYY is a widely adopted mechanism. However, XXXXXXXX. By leveraging the XXXXX, we can YYYYYY. We tested our YYYYYY. Experiment results show that ZZZZZZZ, which can help extend the lifetime of NVRAM and improve performance.

2. By enabling efficient XXXX, YYY serve as the foundation for ZZZ. For example: By enabling efficient insertions, point lookups, and range queries, key-value stores serve as the foundation for this growing group of important applications.

3. For write-intensive workloads, key-value stores based on Log-Structured Merge-Trees(LSM-trees)[1] have become the state of the art. Various distributed and local stores built on LSM-trees are widely deployed in large-scale production environments, such as BigTable [2] and LevelDB [3] at Google, Cassandra [4], HBase [5] and RocksDB [6] at Facebook, and Riak [7] at Basho. The main advantage of LSM-trees over other indexing structures (such as B-trees) is that they maintain sequential access patterns for writes. Small updates on B-trees may involve many random writes, and are hence not efficient on either solid-state storage devices or hard-disk drives.
