Summary: If the corruption of a table file is done before flushing, then db manifest may record the checksum for the corrupted table, which results in "matching checksums" when backup engine tries to verfiy the checksum, and causes a flaky test. Fix the issue by adding `Flush()` before trying to corrupt a table file in *db*. Pull Request resolved: https://github.com/facebook/rocksdb/pull/7082 Test Plan: `buck test` Without the fix, failed 5 of 100 tests. Suspected whether the pseudo randomness causes the issue: doubling `keys_iteration` resulted in 2 of 100 tests failed; deterministically corrupting tables file also caused 2 of 100 tests to fail. With the fix, passed 200 of 200 tests. Reviewed By: pdillinger Differential Revision: D22375421 Pulled By: gg814 fbshipit-source-id: 7304618e7520684b6087e42d0b58329c5ad18329
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.
