Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/12677 The patch contains two fixes related to printing `PutEntity` records with `ldb dump_wal`: 1) It adds the key to the printout (it was missing earlier). 2) It restores the formatting flags of the output stream after dumping the wide-column structure so that any `hex` flag that might have been set does not affect subsequent printing of e.g. sequence numbers.

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.

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.
