Summary: In this patch, try to allocate the whole iterator tree starting from DBIter from an arena 1. ArenaWrappedDBIter is created when serves as the entry point of an iterator tree, with an arena in it. 2. Add an option to create iterator from arena for following iterators: DBIter, MergingIterator, MemtableIterator, all mem table's iterators, all table reader's iterators and two level iterator. 3. MergeIteratorBuilder is created to incrementally build the tree of internal iterators. It is passed to mem table list and version set and add iterators to it. Limitations: (1) Only DB::NewIterator() without tailing uses the arena. Other cases, including readonly DB and compactions are still from malloc (2) Two level iterator itself is allocated in arena, but not iterators inside it.

dynamic_bloom: replace some divide (remainder) operations with shifts in locality mode, and other improvements Summary: This patch changes meaning of options.bloom_locality: 0 means disable cache line optimization and any positive number means use CACHE_LINE_SIZE as block size (the previous behavior is the block size will be CACHE_LINE_SIZE*options.bloom_locality). By doing it, the divide operations inside a block can be replaced by a shift. Performance is improved: https://reviews.facebook.net/P471 Also, improve the basic algorithm in two ways: (1) make sure num of blocks is an odd number (2) rotate bytes after every probe in locality mode. Since the divider is 2^n, unless doing it, we are never able to use all the bits.

Summary: At the end of BackgroundCallCompaction(), we call SignalAll(), even though we don't need to. If compaction hasn't done anything and there's another compaction running, there is no need to signal on the condition variable. Doing so creates a tight feedback loop which results in log files like: wait for memtable flush compaction nothing to do wait for memtable flush compaction nothing to do This change eliminates that Test Plan: make check Also: icanadi@dev1440 ~ $ grep "nothing to do" /fast-rocksdb-tmp/rocksdb_test/column_family_test/LOG | wc -l 7435 icanadi@dev1440 ~ $ grep "nothing to do" /fast-rocksdb-tmp/rocksdb_test/column_family_test/LOG | wc -l 372 First version is before the change, second version is after the change.

Summary: We've seen some production issues where column family is detected as stale, although there is only one column family in the system. This is a quick fix that: 1) doesn't flush stale column families if there's only one of them 2) Use 4 as a coefficient instead of 2 for determening when a column family is stale. This will make flushing less aggressive, while still keep a nice dynamic flushing of very stale CFs.

Summary: https://github.com/facebook/rocksdb/commit/220132b65ec17abb037d3e79d5abf6ca8d797b96 correctly fixed the issue of thread ID printing when terminating a thread. Nothing wrong with it. This diff prints the ID in the same way as in PosixLogger::logv() so that users can be more easily to correlates them. Test Plan: run env_test and make sure it prints correctly.

Summary: 1. Move disOwnNativeHandle() function from RocksDB to RocksObject to allow other RocksObject to use disOwnNativeHandle() when its ownership of native handle has been transferred. 2. RocksObject now has an abstract implementation of dispose(), which does the following two things. First, it checks whether both isOwningNativeHandle() and isInitialized() return true. If so, it will call the protected abstract function dispose0(), which all the subclasses of RocksObject should implement. Second, it sets nativeHandle_ = 0. This redesign ensure all subclasses of RocksObject have the same dispose behavior. 3. All subclasses of RocksObject now should implement dispose0() instead of dispose(), and dispose0() will be called only when isInitialized() returns true.

ThreadPool to allow decrease number of threads and increase of number of threads is to be instantly scheduled Summary: Add a feature to decrease the number of threads in thread pool. Also instantly schedule more threads if number of threads is increased. Here is the way it is implemented: each background thread needs its thread ID. After decreasing number of threads, all threads are woken up. The thread with the largest thread ID will terminate. If there are more threads to terminate, the thread will wake up all threads again. Another change is made so that when number of threads is increased, more threads are created and all previous excessive threads are woken up to do the work. Test Plan: Add a unit test.

Summary: This diff adds rapidjson (https://code.google.com/p/rapidjson/) to RocksDB repository. First step to adding JSON is to add a JSON parser :) I'm not sure if rapidjson is the right choice. I only considered folly as an alternative. Using folly JSON parser has serious downsides. I tried extracting folly::json from the folly library. However, it depends on folly::dynamic, which basically depends on everything else. I would prefer to avoid adding complete folly library as RocksDB dependency. Folly has a lot of its own dependencies (https://github.com/facebook/folly) and also looks like open source world has some trouble installing it (https://groups.google.com/forum/#!forum/facebook-folly -- 60% of the posts are compile errors). We can discuss this if you think otherwise. RapidJSON does not have any dependencies whatsoever. No boost, no STL. We don't need to compile it since it's all header files. The performance results are also impressive: https://code.google.com/p/rapidjson/wiki/Performance. However, I'll make sure to write code in a way that we can easily switch JSON implementations going forward.
