Summary: Since the hashes should not be persisted in output_validator nor mock_env. Also updated NPHash64 to use 64-bit seed, and comments. Pull Request resolved: https://github.com/facebook/rocksdb/pull/7632 Test Plan: make check, and new build setting that enables modification to NPHash64, to check for behavior depending on specific values. Added that setting to one of the CircleCI configurations. Reviewed By: jay-zhuang Differential Revision: D24833780 Pulled By: pdillinger fbshipit-source-id: 02a57652ccf1ac105fbca79e77875bb7bf7c071f |

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.
Start with example usage here: https://github.com/facebook/rocksdb/tree/master/examples
See the github wiki for more explanation.
The public interface is in include/. Callers should not include or
rely on the details of any other header files in this package. Those
internal APIs may be changed without warning.
Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/ and https://rocksdb.slack.com/
