Summary: Move them to MutableCFOptions and perform appropriate refactorings to make that work. I didn't want to mix up refactoring with interesting functional changes. Potentially non-trivial bits here: * During DB Open or RegisterRecordSeqnoTimeWorker we use `GetLatestMutableCFOptions()` because either (a) there might not be a current version, or (b) we are in the process of applying the desired next options. * Upgrade some test infrastructure to allow some options in MutableCFOptions to be mutable (should be a temporary state) * Fix a warning that showed up about uninitialized `paranoid_memory_checks` Pull Request resolved: https://github.com/facebook/rocksdb/pull/13114 Test Plan: existing tests, manually check options are still not settable with SetOptions Reviewed By: jowlyzhang Differential Revision: D65429031 Pulled By: pdillinger fbshipit-source-id: 6e0906d08dd8ddf62731cefffe9b8d94149942b9 |

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/main/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.
