Summary: This change adds pmem-rocksdb-plugin link in PLUGINS.md. The link is: https://github.com/pmem/pmem-rocksdb-plugin. It provides a collection plugins to enable Persistent Memory (PMEM) on RocksDB. The pmem-rocksdb-plugin repo contains RocksDB’s plugins for LSM-tree based KV store to fit it on the PMEM by effectively utilize its characteristics. The first two basic plugins are: 1) Providing a filesystem API wrapper to write RocksDB's WAL (Write Ahead Log) files on PMEM to optimize write performance. 2) Using PMEM as secondary cache to optimize read performance.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
