Summary: The internal WriteBatch doc wrongly indicated which optypes are followed by varstring. Updated some optypes according to the following code:76383bea5d/db/write_batch.cc (L418-L429)
The `Iterator::Refresh()` + `DeleteRange()` bug was fixed in https://github.com/facebook/rocksdb/issues/9258; removed the warnings. `GetMergeOperands()` does populate `*number_of_operands` including upon successful return:76383bea5d/db/db_impl/db_impl.cc (L1917-L1919)

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.
