Summary: In hopes of eventually removing some ugly and awkard code for compress_format_version < 2, users can no longer write files in that format and its read support is marked deprecated. For continuing to test that read support, there is a back door to writing the files in unit tests. If format_version < 2 is specified, it is quietly sanitized to 2. (This is similar to other BlockBasedTableOptions.) Pull Request resolved: https://github.com/facebook/rocksdb/pull/13463 Test Plan: unit tests updated.

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.
