Summary: Existing API `VerifyChecksum()` allows application to verify sst files' block checksums. Since whole file, user-specified checksum is tracked in MANIFEST, we can expose a new API to verify sst files' file checksums. ``` // Compute table file checksums if applicable and compare with MANIFEST. // Returns OK if no file has mismatching whole-file checksum. Status DB::VerifyFileChecksums(const ReadOptions& /*read_options*/); ``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/7578 Test Plan: make check Reviewed By: pdillinger Differential Revision: D24436783 Pulled By: riversand963 fbshipit-source-id: 52b51519b842f2b3c4e3351998a97c86cbec85b3
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.

internal APIs may be changed without warning.
