Hui Xiao	e66e6d2faa	Use SpecialEnv to speed up some slow BackupEngineRateLimitingTestWithParam (#9974) ... Summary: **Context:** `BackupEngineRateLimitingTestWithParam.RateLimiting` and `BackupEngineRateLimitingTestWithParam.RateLimitingVerifyBackup` involve creating backup and restoring of a big database with rate-limiting. Using the normal env with a normal clock requires real elapse of time (13702 - 19848 ms/per test). As suggested in https://github.com/facebook/rocksdb/pull/8722#discussion_r703698603, this PR is to speed it up with SpecialEnv (`time_elapse_only_sleep=true`) where its clock accepts fake elapse of time during rate-limiting (100 - 600 ms/per test) **Summary:** - Added TEST_ function to set clock of the default rate limiters in backup engine - Shrunk testdb by 10 times while keeping it big enough for testing - Renamed some test variables and reorganized some if-else branch for clarity without changing the test Pull Request resolved: https://github.com/facebook/rocksdb/pull/9974 Test Plan: - Run tests pre/post PR the same time to verify the tests are sped up by 90 - 95% `BackupEngineRateLimitingTestWithParam.RateLimiting` Pre: ``` [ RUN ]

Peter Dillinger	6534c6dea4	Fix remaining uses of "backupable" (#9792) ... Summary: Various renaming and fixes to get rid of remaining uses of "backupable" which is terminology leftover from the original, flawed design of BackupableDB. Now any DB can be backed up, using BackupEngine.

Peter Dillinger	cff0d1e8e6	New backup meta schema, with file temperatures (#9660) ... Summary: The primary goal of this change is to add support for backing up and restoring (applying on restore) file temperature metadata, without committing to either the DB manifest or the FS reported "current" temperatures being exclusive "source of truth". To achieve this goal, we need to add temperature information to backup metadata, which requires updated backup meta schema. Fortunately I prepared for this in https://github.com/facebook/rocksdb/issues/8069, which began forward compatibility in version 6.19.0 for this kind of schema update. (Previously, backup meta schema was not extensible! Making this schema update public will allow some other "nice to have" features like taking backups with hard links, and avoiding crc32c checksum computation when another checksum is already available.) While schema version 2 is newly public, the default schema version is still 1. Until we change the default, users will need to set to 2 to enable features like temperature data backup+restore. New metadata like temperature information will be ignored with a warning in versions before this change and since 6.19.0. The metadata is considered ignorable because a functioning DB can be restored without it. Some detail: * Some renaming because "future schema" is now just public schema 2. * Initialize some atomics in TestFs (linter reported) * Add temperature hint support to SstFileDumper (used by BackupEngine) Pull Request resolved: https://github.com/facebook/rocksdb/pull/9660 Test Plan: related unit test majorly updated for the new functionality, including some shared testing support for tracking temperatures in a FS. Some other tests and testing hooks into production code also updated for making the backup meta schema change public.

Peter Dillinger	78aee6fedc	Remove obsolete backupable_db.h, utility_db.h (#9438) ... Summary: This also removes the obsolete names BackupableDBOptions and UtilityDB. API users must now use BackupEngineOptions and DBWithTTL::Open. In C API, `rocksdb_backupable_db_*` is replaced `rocksdb_backup_engine_*`. Similar renaming in Java API.

Peter Dillinger	3bfd3ed2f3	Begin forward compatibility for new backup meta schema (#8069) ... 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.
