Summary: Seems like NewTotalOrderPlainTableFactory is useless and is semantically incorrect.

Summary: In this patch, we enhance HashLinkList memtable to reduce performance outliers when a bucket contains too many entries. We switch to skip list for this case to enable binary search. Add threshold_use_skiplist parameter to determine when a bucket needs to switch to skip list. The new data structure is documented in comments in the codes.

Summary: As discussed in our internal group, we don't get much use of seek compaction at the moment, while it's making code more complicated and slower in some cases. This diff removes seek compaction and (hopefully) all code that was introduced to support seek compaction. There is one test case that relied on didIO information. I'll try to find another way to implement it.

Summary: This diff addresses task #4296714 and rethinks how users provide us with TablePropertiesCollectors as part of Options. Here's description of task #4296714: I'm debugging #4295529 and noticed that our count of user properties kDeletedKeys is wrong. We're sharing one single InternalKeyPropertiesCollector with all Table Builders. In LOG Files, we're outputting number of kDeletedKeys as connected with a single table, while it's actually the total count of deleted keys since creation of the DB. For example, this table has 3155 entries and 1391828 deleted keys. The problem with current approach that we call methods on a single TablePropertiesCollector for all the tables we create. Even worse, we could do it from multiple threads at the same time and TablePropertiesCollector has no way of knowing which table we're calling it for. Good part: Looks like nobody inside Facebook is using Options::table_properties_collectors. This means we should be able to painfully change the API. In this change, I introduce TablePropertiesCollectorFactory. For every table we create, we call `CreateTablePropertiesCollector`, which creates a TablePropertiesCollector for a single table. We then use it sequentially from a single thread, which means it doesn't have to be thread-safe. Test Plan: Added a test in table_properties_collector_test that fails on master (build two tables, assert that kDeletedKeys count is correct for the second one). Also, all other tests Reviewers: sdong, dhruba, haobo, kailiu Reviewed By: kailiu CC: leveldb Differential Revision: https://reviews.facebook.net/D18579

Summary: This diff adds a new CompactionFilterV2 API that roll up the decisions of kv pairs during compactions. These kv pairs must share the same key prefix. They are buffered inside the db. typedef std::vector<Slice> SliceVector; virtual std::vector<bool> Filter(int level, const SliceVector& keys, const SliceVector& existing_values, std::vector<std::string>* new_values, std::vector<bool>* values_changed ) const = 0; Application can override the Filter() function to operate on the buffered kv pairs.

Summary: (1) Fix SanitizeOptions() to also check HashLinkList. The current dynamic case just happens to work because the 2 classes have the same layout. (2) Do not delete SliceTransform object in HashSkipListFactory and HashLinkListFactory destructor. Reason: SanitizeOptions() enforces prefix_extractor and SliceTransform to be the same object when Hash**Factory is used. This makes the behavior strange: when Hash**Factory is used, prefix_extractor will be released by RocksDB. If other memtable factory is used, prefix_extractor should be released by user.

Summary: This diff does two things: (1) Log::Reader does not report a corruption when the last record in a log or manifest file is truncated (meaning that log writer died in the middle of the write). Inherited the code from LevelDB: https://code.google.com/p/leveldb/source/detail?r=269fc6ca9416129248db5ca57050cd5d39d177c8# (2) Turn off mmap writes for all writes to log and manifest files (2) is necessary because if we use mmap writes, the last record is not truncated, but is actually filled with zeros, making checksum fail. It is hard to recover from checksum failing. Test Plan: Added unit tests from LevelDB Actually recovered a "corrupted" MANIFEST file.

Since WriteBatch is not a very smart function (it takes raw CF id), client can add data to WriteBatch for column family that doesn't exist. In that case, we need to gracefully return failure status from DB::Write(). To do that, I added a return Status to WriteBatch functions PutCF, DeleteCF and MergeCF.
