Yueh-Hsuan Chiang e29a73b89e Fixed a tsan warning in db_stress.cc 
Summary:
Fixed the following tsan warning in db_stress.cc

  WARNING: ThreadSanitizer: data race (pid=3163194)

    #2 StartThreadWrapper util/env_posix.cc:1648 (db_stress+0x00000028bbbd)

The cause is that in VerifyDb(), the static local const variable long max_key
can be read and written at the same time.  This patch fixed it by making it
non-static.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

Build Status

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 specially 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/
