Levi Tamasi 72daa92d3a Refactor blob file creation logic (#6066)
Summary:
The patch refactors and cleans up the logic around creating new blob files
by moving the common code of `SelectBlobFile` and `SelectBlobFileTTL`
to a new helper method `CreateBlobFileAndWriter`, bringing the implementation
of `SelectBlobFile` and `SelectBlobFileTTL` into sync, and increasing encapsulation
by adding new constructors for `BlobFile` and `BlobLogHeader`.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6066

Test Plan:
Ran `make check` and used the BlobDB mode of `db_bench` to sanity test both
the TTL and the non-TTL code paths.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

Linux/Mac Build Status Windows Build status PPC64le Build Status

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/
