Levi Tamasi 217ce20021 Remove GetSortedWalFiles/GetCurrentWalFile from the crash test (#6491 ) Summary: Currently, `db_stress` tests a randomly picked one of `GetLiveFiles`, `GetSortedWalFiles`, and `GetCurrentWalFile` with a 1/N chance when the command line parameter `get_live_files_and_wal_files_one_in` is specified. The problem is that `GetSortedWalFiles` and `GetCurrentWalFile` are unreliable in the sense that they can return errors if another thread removes a WAL file while they are executing (which is a perfectly plausible and legitimate scenario). The patch splits this command line parameter into three (one for each API), and changes the crash test script so that only `GetLiveFiles` is tested during our continuous crash test runs.

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/
