Make it easier to start using RocksDB Summary: This diff is addressing multiple things with a single goal -- to make RocksDB easier to use: * Add some functions to Options that make RocksDB easier to tune. * Add example code for both simple RocksDB and RocksDB with Column Families. * Rewrite our README.md Regarding Options, I took a stab at something we talked about for a long time: * https://www.facebook.com/groups/rocksdb.dev/permalink/563169950448190/ I added functions: * IncreaseParallelism() -- easy, increases the thread pool and max_background_compactions * OptimizeLevelStyleCompaction(memtable_memory_budget) -- the easiest way to optimize rocksdb for less stalls with level style compaction. This is very likely not ideal configuration. Feel free to suggest improvements. I used some of Mark's suggestions from here: https://github.com/facebook/rocksdb/issues/54 * OptimizeUniversalStyleCompaction(memtable_memory_budget) -- optimize for universal compaction. Test Plan: compiled rocksdb. ran examples. Reviewers: dhruba, MarkCallaghan, haobo, sdong, yhchiang Reviewed By: dhruba CC: leveldb Differential Revision: https://reviews.facebook.net/D18621

CompactFiles, EventListener and GetDatabaseMetaData Summary: This diff adds three sets of APIs to RocksDB. = GetColumnFamilyMetaData = * This APIs allow users to obtain the current state of a RocksDB instance on one column family. * See GetColumnFamilyMetaData in include/rocksdb/db.h = EventListener = * A virtual class that allows users to implement a set of call-back functions which will be called when specific events of a RocksDB instance happens. * To register EventListener, simply insert an EventListener to ColumnFamilyOptions::listeners = CompactFiles = * CompactFiles API inputs a set of file numbers and an output level, and RocksDB will try to compact those files into the specified level. = Example = * Example code can be found in example/compact_files_example.cc, which implements a simple external compactor using EventListener, GetColumnFamilyMetaData, and CompactFiles API.
