Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/15098 Compute the base block checksum in `CompressAndVerifyBlock()` before `verify_compression` decompresses the compressed output. Parallel compression stores that base checksum on the block rep so worker threads can keep the CPU-heavy checksum and verification work off the ordered write path; the writer only applies the offset context modifier before writing the trailer. Update the regression test to cover both serial and parallel compression paths. Reviewed By: pdillinger Differential Revision: D115950785 fbshipit-source-id: b5e47f7d7c41680e7e7907443fc805bc0d043d6e
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.
