Summary: reland https://reviews.facebook.net/D62523 - Update SstFileWriter to include a property for a global sequence number in the SST file `rocksdb.external_sst_file.global_seqno` - Update TableProperties to be aware of the offset of each property in the file - Update BlockBasedTableReader and Block to be able to honor the sequence number in `rocksdb.external_sst_file.global_seqno` property and use it to overwrite all sequence number in the file Something worth mentioning is that we don't update the seqno in the index block since and when doing a binary search, the reason for that is that it's guaranteed that SST files with global seqno will have only one user_key and each key will have seqno=0 encoded in it, This mean that this key is greater than any other key with seqno> 0. That mean that we can actually keep the current logic for these blocks Test Plan: unit tests Reviewers: sdong, yhchiang Subscribers: andrewkr, dhruba Differential Revision: https://reviews.facebook.net/D65211

Summary: InlineSkipList::InsertConcurrently should invalidate the sequential-insertion cache prev_[] for all inserts of multi-level nodes, not just those that increase the height of the skip list. The invariant for prev_ is that prev_[i] (i > 0) is supposed to be the predecessor of prev_[0] at level i. Before this diff InsertConcurrently could violate this constraint when inserting a multi-level node after prev_[i] but before prev_[0]. This diff also reenables kConcurrentSkipList as db_test's MultiThreaded/MultiThreadedDBTest.MultiThreaded/29. Test Plan: 1. unit tests 2. temporarily hack kConcurrentSkipList timing so that it is fast but has a 1.5% failure rate on my dev box (1ms stagger on thread launch, 1s test duration, failure rate baseline over 1000 runs) 3. observe 1000 passes post-fix Reviewers: igor, sdong Reviewed By: sdong Subscribers: MarkCallaghan, dhruba Differential Revision: https://reviews.facebook.net/D53751

Summary: Moved all the tests that verify property correctness into a separate file. The goal is to reduce compile time and complexity of db_test. I didn't add parallelism for db_properties_test, even though these tests were parallelized in db_test, since the file is small enough that it won't matter. Some of these moves may be controversial since it's hard to say whether the test is "verifying property correctness," or "using properties to verify rocksdb's correctness." I'm interested in any opinions.

Summary: DBTest.SuggestCompactRangeTest fails for the case when jemalloc is disabled, including ASAN and valgrind builds.
