What is the purpose of the Options object in RocksDB's API?

The Options object is the central configuration structure passed when opening a RocksDB database, controlling nearly every tunable aspect of its behavior.

• Covers settings like MemTable size, compaction style, compression, block cache configuration, and the number of background threads
• Some settings apply database-wide, while others can be set per column family for finer-grained control
• Sensible defaults exist for most options, letting a simple application get started without tuning everything manually

Because so much of RocksDB's performance behavior is configurable, the Options object is effectively where an operator translates their understanding of a workload into RocksDB's actual runtime behavior.
