Yueh-Hsuan Chiang 0bb8ea56be [RocksDB Options File] Add TableOptions section and support BlockBasedTable 
Summary:
Introduce TableOptions section and support BlockBasedTable in RocksDB
options file.  A TableOptions section has the following format:

  [TableOptions/<FactoryClassName> "<ColumnFamily Name>"]

which includes information about its TableFactory class and belonging
column family.  Below is an example TableOptions section of a
BlockBasedTableOptions that belongs to the default column family:

  [TableOptions/BlockBasedTable "default"]
    format_version=0
    whole_key_filtering=true
    block_size_deviation=10
    block_size=4096
    block_restart_interval=16
    filter_policy=nullptr
    no_block_cache=false
    checksum=kCRC32c
    cache_index_and_filter_blocks=false
    index_type=kBinarySearch
    hash_index_allow_collision=true
    flush_block_policy_factory=FlushBlockBySizePolicyFactory

Currently, Cache-type options (i.e., block_cache and block_cache_compressed)
are not supported.

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

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 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/
