Summary: For the sake of making our options simpler, we should keep options.h as simple as possible and move more advanced/less common options to advaned_options.h I started with ColumnFamilyOptions and also did some re-ordering I have moved all ColumnFamilyOptions to advanced_options.h and only left these options in options.h ``` const Comparator* comparator = BytewiseComparator(); std::shared_ptr<MergeOperator> merge_operator = nullptr; const CompactionFilter* compaction_filter = nullptr; std::shared_ptr<CompactionFilterFactory> compaction_filter_factory = nullptr; size_t write_buffer_size = 64 << 20; CompressionType compression; int level0_file_num_compaction_trigger = 4; bool disable_auto_compactions = false; ``` Please feel free to comment on specific options if you think they should be advanced or should not be Closes https://github.com/facebook/rocksdb/pull/1847 Differential Revision: D4519996 Pulled By: IslamAbdelRahman fbshipit-source-id: abebd9a |

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 specially 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/
