Summary: - Completed the switch statement for all possible `Code` values (the only one missing was `kCompactionTooLarge`). - Removed the default case so compiler can alert us if a new value is added to `Code` without handling it in `Status::ToString()`. Pull Request resolved: https://github.com/facebook/rocksdb/pull/7872 Test Plan: verified the log message for this scenario looks right ``` 2021/01/15-17:26:34.564450 7fa6845fe700 [ERROR] [/db_impl/db_impl_compaction_flush.cc:2621] Waiting after background compaction error: Compaction too large: , Accumulated background error counts: 1 ``` Reviewed By: ramvadiv Differential Revision: D25934539 Pulled By: ajkr fbshipit-source-id: 2e0b3c0d993e356a4987276d6f8a163f0ee8be7a |

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/ and https://rocksdb.slack.com/
