Summary: Deprecate options.soft_rate_limit, which is hard to tune, with options.soft_pending_compaction_bytes_limit, which would trigger the slowdown if estimated pending compaction bytes exceeds the threshold. The hope is to make it more striaght-forward to tune. Test Plan: Modify DBTest.SoftLimit to cover options.soft_pending_compaction_bytes_limit instead; run all unit tests.

Summary: This patch adds OptionsUtil::LoadOptionsFromFile() and OptionsUtil::LoadLatestOptionsFromDB(), which allow developers to construct DBOptions and ColumnFamilyOptions from a RocksDB options file. Note that most pointer-typed options such as merge_operator will not be constructed. With this API, developers no longer need to remember all the options in order to reopen an existing rocksdb instance like the following: DBOptions db_options; std::vector<std::string> cf_names; std::vector<ColumnFamilyOptions> cf_opts; // Load primitive-typed options from an existing DB OptionsUtil::LoadLatestOptionsFromDB( dbname, &db_options, &cf_names, &cf_opts); // Initialize necessary pointer-typed options cf_opts[0].merge_operator.reset(new MyMergeOperator()); ... // Construct the vector of ColumnFamilyDescriptor std::vector<ColumnFamilyDescriptor> cf_descs; for (size_t i = 0; i < cf_opts.size(); ++i) { cf_descs.emplace_back(cf_names[i], cf_opts[i]); } // Open the DB DB* db = nullptr; std::vector<ColumnFamilyHandle*> cf_handles; auto s = DB::Open(db_options, dbname, cf_descs, &handles, &db); Test Plan: Augment existing tests in column_family_test options_test db_test Reviewers: igor, IslamAbdelRahman, sdong, anthony Reviewed By: anthony Subscribers: dhruba, leveldb Differential Revision: https://reviews.facebook.net/D49095

Summary: Since Andres' internship is over, I took over https://reviews.facebook.net/D42555 and rebased and simplified it a bit. The behavior in this diff is a bit simpler than in D42555: * only merge operators are passed through FilterMergeValue(). If fitler function returns true, the merge operator is ignored * compaction filter is *not* called on: 1) results of merge operations and 2) base values that are getting merged with merge operands (the second case was also true in previous diff) Do we also need a compaction filter to get called on merge results?

Summary: This patch fixes #7460559. It introduces SingleDelete as a new database operation. This operation can be used to delete keys that were never overwritten (no put following another put of the same key). If an overwritten key is single deleted the behavior is undefined. Single deletion of a non-existent key has no effect but multiple consecutive single deletions are not allowed (see limitations). In contrast to the conventional Delete() operation, the deletion entry is removed along with the value when the two are lined up in a compaction. Note: The semantics are similar to @igor's prototype that allowed to have this behavior on the granularity of a column family ( https://reviews.facebook.net/D42093 ). This new patch, however, is more aggressive when it comes to removing tombstones: It removes the SingleDelete together with the value whenever there is no snapshot between them while the older patch only did this when the sequence number of the deletion was older than the earliest snapshot. Most of the complex additions are in the Compaction Iterator, all other changes should be relatively straightforward. The patch also includes basic support for single deletions in db_stress and db_bench. Limitations: - Not compatible with cuckoo hash tables - Single deletions cannot be used in combination with merges and normal deletions on the same key (other keys are not affected by this) - Consecutive single deletions are currently not allowed (and older version of this patch supported this so it could be resurrected if needed) Test Plan: make all check Reviewers: yhchiang, sdong, rven, anthony, yoshinorim, igor Reviewed By: igor Subscribers: maykov, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D43179

Summary: In the first implementation of BackupEngine, LATEST_BACKUP was the commit point. The backup became committed after the write to LATEST_BACKUP completed. However, we can avoid the need for LATEST_BACKUP. Instead of write to LATEST_BACKUP, the commit point can be the rename from `meta/<backup_id>.tmp` to `meta/<backup_id>`. Once we see that there exists a file `meta/<backup_id>` (without tmp), we can assume that backup is valid. In this diff, we still write out the file LATEST_BACKUP. We need to do this so that we can maintain backward compatibility. However, the new version doesn't depend on this file anymore. We get the latest backup by `ls`-ing `meta` directory.

Summary: Initial implementation of Pessimistic Transactions. This diff contains the api changes discussed in D38913. This diff is pretty large, so let me know if people would prefer to meet up to discuss it. MyRocks folks: please take a look at the API in include/rocksdb/utilities/transaction[_db].h and let me know if you have any issues. Also, you'll notice a couple of TODOs in the implementation of RollbackToSavePoint(). After chatting with Siying, I'm going to send out a separate diff for an alternate implementation of this feature that implements the rollback inside of WriteBatch/WriteBatchWithIndex. We can then decide which route is preferable. Next, I'm planning on doing some perf testing and then integrating this diff into MongoRocks for further testing.
