Andrew Kryczka 0a5b16c7c5 Cleanup staging directory at start of checkpoint (#4035)
Summary:
- Attempt to clean the checkpoint staging directory before starting a checkpoint. It was already cleaned up at the end of checkpoint. But it wasn't cleaned up in the edge case where the process crashed while staging checkpoint files.
- Attempt to clean the checkpoint directory before calling `Checkpoint::Create` in `db_stress`. This handles the case where checkpoint directory was created by a previous `db_stress` run but the process crashed before cleaning it up.
- Use `DestroyDB` for cleaning checkpoint directory since a checkpoint is a DB.

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

Linux/Mac Build Status Windows Build status PPC64le 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/
