Summary: An early design of BackupEngine used stackable DB, so I guess a DB had to opt-in to being backupable. Unfortunately the naming of that obsolete design still infects our public API and implementation. This change fixes the public API, with a deprecated backward-compatibility header. `BackupableDBOptions` is renamed to `BackupEngineOptions` (copy-replace in the public header) and backup_engine.h replaces backupable_db.h (present for backward compatibility). The only other change in backupable_db.h -> backup_engine.h is cleaning up headers. Later changes will fix the internal implementation. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8274 Test Plan: The internal implementation of BackupEngine uses the name BackupEngineOptions, while the unit tests use the old name BackupableDBOptions. This gives me confidence that both still work. Reviewed By: mrambacher Differential Revision: D28259471 Pulled By: pdillinger fbshipit-source-id: a25dbe327b9772143488e7bb0ec7139ee42d0613
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.

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/
