Yu Zhang 16bdb1f999 Add timestamp support to DBImplReadOnly (#10004 ) Summary: This PR adds timestamp support to a read only DB instance opened as `DBImplReadOnly`. A follow up PR will add the same support to `CompactedDBImpl`. With this, read only database has these timestamp related APIs: `ReadOptions.timestamp` : read should return the latest data visible to this specified timestamp `Iterator::timestamp()` : returns the timestamp associated with the key, value `DB:Get(..., std::string* timestamp)` : returns the timestamp associated with the key, value in `timestamp` Test plan (on devserver): ``` $COMPILE_WITH_ASAN=1 make -j24 all $./db_with_timestamp_basic_test --gtest_filter=DBBasicTestWithTimestamp.ReadOnlyDB* ``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/10004 Reviewed By: riversand963 Differential Revision: D36434422 Pulled By: jowlyzhang fbshipit-source-id: 5d949e65b1ffb845758000e2b310fdd4aae71cfb		3 years ago

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)

This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.

Start with example usage here: https://github.com/facebook/rocksdb/tree/main/examples

See the github wiki for more explanation.

The public interface is in include/. Callers should not include or rely on the details of any other header files in this package. Those internal APIs may be changed without warning.

Questions and discussions are welcome on the RocksDB Developers Public Facebook group and email list on Google Groups.
