Summary: Add a new field: BackupableDBOptions.max_background_copies. CreateNewBackup() and RestoreDBFromBackup() will use this number of threads to perform copies. If there is a backup rate limit, then max_background_copies must be 1. Update backupable_db_test.cc to test multi-threaded backup and restore. Update backupable_db_test.cc to test backups when the backup environment is not the same as the database environment. Test Plan: Run ./backupable_db_test Run valgrind ./backupable_db_test Run with TSAN and ASAN Reviewers: yhchiang, rven, anthony, sdong, igor Reviewed By: igor Subscribers: yhchiang, anthony, sdong, leveldb, dhruba Differential Revision: https://reviews.facebook.net/D40725 |

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 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.
