Summary: Add some basic test for user-defined timestamp to db_stress. Currently, read with timestamp always tries to read using the current timestamp. Due to the per-key timestamp-sequence ordering constraint, we only add timestamp- related tests to the `NonBatchedOpsStressTest` since this test serializes accesses to the same key and uses a file to cross-check data correctness. The timestamp feature is not supported in a number of components, e.g. Merge, SingleDelete, DeleteRange, CompactionFilter, Readonly instance, secondary instance, SST file ingestion, transaction, etc. Therefore, db_stress should exit if user enables both timestamp and these features at the same time. The (currently) incompatible features can be found in `CheckAndSetOptionsForUserTimestamp`. This PR also fixes a bug triggered when timestamp is enabled together with `index_type=kBinarySearchWithFirstKey`. This bug fix will also be in another separate PR with more unit tests coverage. Fixing it here because I do not want to exclude the index type from crash test.

Summary: Since our stress/crash tests by default generate values of size 8, 16, or 24, it does not make much sense to set `min_blob_size` to 256.

Summary: This does not add any new public APIs or published functionality, but adds the ability to read and use (and in tests, write) backups with a new meta file schema, based on the old schema but not forward-compatible (before this change). The new schema enables some capabilities not in the old: * Explicit versioning, so that users get clean error messages the next time we want to break forward compatibility. * Ignoring unrecognized fields (with warning), so that new non-critical features can be added without breaking forward compatibility. * Rejecting future "non-ignorable" fields, so that new features critical to some use-cases could potentially be added outside of linear schema versions, with broken forward compatibility. * Fields at the end of the meta file, such as for checksum of the meta file's contents (up to that point) * New optional 'size' field for each file, which is checked when present * Optionally omitting 'crc32' field, so that we aren't required to have a crc32c checksum for files to take a backup. (E.g. to support backup via hard links and to better support file custom checksums.) Because we do not have a JSON parser and to share code, the new schema is simply derived from the old schema. BackupEngine code is updated to allow missing checksums in some places, and to make that easier, `has_checksum` and `verify_checksum_after_work` are eliminated. Empty `checksum_hex` indicates checksum is unknown. I'm not too afraid of regressing on data integrity, because (a) we have pretty good test coverage of corruption detection in backups, and (b) we are increasingly relying on the DB itself for data integrity rather than it being an exclusive feature of backups.

Summary: In previous codebase, if WAL is used, all the retryable IO Error will be treated as hard error. So write is stalled. In this PR, the retryable IO error from WAL sync is separated from SST file flush io error. If WAL Sync is ok and retryable IO Error only happens during SST flush, the error is mapped to soft error. So user can continue insert to Memtable and append to WAL. Resolve the bug that if WAL sync fails, the memtable status does not roll back due to calling PickMemtable early than calling and checking SyncClosedLog.

Summary: WriteController had a number of issues: * It could introduce a delay of 1ms even if the write rate never exceeded the configured delayed_write_rate. * The DB-wide delayed_write_rate could be exceeded in a number of ways with multiple column families: * Wiping all pending delay "debts" when another column family joins the delay with GetDelayToken(). * Resetting last_refill_time_ to (now + sleep amount) means each column family can write with delayed_write_rate for large writes. * Updating bytes_left_ for a partial refill without updating last_refill_time_ would essentially give out random bonuses, especially to medium-sized writes. Now the code is much simpler, with these issues fixed. See comments in the new code and new (replacement) tests.

Summary: When timestamp is enabled, key comparison should take this into account. In `BlockBasedTableReader::Get()`, `BlockBasedTableReader::MultiGet()`, assume the target key is `key`, and the timestamp upper bound is `ts`. The highest key in current block is (key, ts1), while the lowest key in next block is (key, ts2). If ``` ts1 > ts > ts2 ``` then ``` (key, ts1) < (key, ts) < (key, ts2) ``` It can be shown that if `Compare()` is used, then we will mistakenly skip the next block. Instead, we should use `CompareWithoutTimestamp()`. The majority of this PR makes some existing tests in `db_with_timestamp_basic_test.cc` parameterized so that different index types can be tested. A new unit test is also added for more coverage.

Summary: For performance purposes, the lower level routines were changed to use a SystemClock* instead of a std::shared_ptr<SystemClock>. The shared ptr has some performance degradation on certain hardware classes. For most of the system, there is no risk of the pointer being deleted/invalid because the shared_ptr will be stored elsewhere. For example, the ImmutableDBOptions stores the Env which has a std::shared_ptr<SystemClock> in it. The SystemClock* within the ImmutableDBOptions is essentially a "short cut" to gain access to this constant resource. There were a few classes (PeriodicWorkScheduler?) where the "short cut" property did not hold. In those cases, the shared pointer was preserved. Using db_bench readrandom perf_level=3 on my EC2 box, this change performed as well or better than 6.17: 6.17: readrandom : 28.046 micros/op 854902 ops/sec; 61.3 MB/s (355999 of 355999 found) 6.18: readrandom : 32.615 micros/op 735306 ops/sec; 52.7 MB/s (290999 of 290999 found) PR: readrandom : 27.500 micros/op 871909 ops/sec; 62.5 MB/s (367999 of 367999 found) (Note that the times for 6.18 are prior to revert of the SystemClock).

Summary: This PR adds support for custom file systems to ldb and sst_dump by adding command line options for specifying --fs_uri and --backup_fs uri (for ldb backup/restore commands). fs_uri is already supported in db_bench and db_stress, and there is already support in ldb and db stress for specifying customized envs. The PR also fixes what looks like a bug in the ldb backup/restore commands. As it is right now, backups can only be made from and to the same environment/file system which does not seem to be the intended behavior. This PR makes it possible to do/restore backups between different envs/file systems. Example: `./ldb backup --fs_uri=zenfs://dev:nvme2n1 --backup_fs_uri=posix:// --backup_dir=/tmp/my_rocksdb_backup --db=rocksdbtest/dbbench ` Pull Request resolved: https://github.com/facebook/rocksdb/pull/8010 Reviewed By: jay-zhuang Differential Revision: D26904654 Pulled By: ajkr fbshipit-source-id: 9b695ed8b944fcc6b27c4daaa9f52e87ee2c1fb4

Summary: Removed confusing, awkward, and undocumented internal API ReadOneLine and replaced with very simple LineFileReader. In refactoring backupable_db.cc, this has the side benefit of removing the arbitrary cap on the size of backup metadata files. Also added Status::MustCheck to make it easy to mark a Status as "must check." Using this, I can ensure that after LineFileReader::ReadLine returns false the caller checks GetStatus(). Also removed some excessive conditional compilation in status.h Pull Request resolved: https://github.com/facebook/rocksdb/pull/8026 Test Plan: added unit test, and running tests with ASSERT_STATUS_CHECKED Reviewed By: mrambacher Differential Revision: D26831687 Pulled By: pdillinger fbshipit-source-id: ef749c265a7a26bb13cd44f6f0f97db2955f6f0f
