Summary: When inplace_update_support and memtable_veirfy_per_key_checksum_on_seek are enabled at the same time, it would cause data race in memtable. inplace_update_support allows key/value pair in place update in memtable. memtable_veirfy_per_key_checksum_on_seek performs key checksum verification during seek. It is possible that one thread is updating the key/value pair in place, while another thread is reading the key/value pair for checksum verification during seek. Therefore, there these 2 configurations could not be enabled at the same time Pull Request resolved: https://github.com/facebook/rocksdb/pull/14023 Test Plan: local stress test run stops reporting race condition Reviewed By: anand1976 Differential Revision: D83812322 Pulled By: xingbowang fbshipit-source-id: 6cb9f0f3faa8deba97305bfe87266f2fe78e0501
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.
