Summary: Recently db_stress starts to use a special Env that keeps all manifest files. This should not apply to checkpoint directory and causes test failure like this: Verification failed: Checkpoint gave inconsistent state. Status is IO error: While mkdir: /dev/shm/rocksdb/rocksdb_crashtest_whitebox/.checkpoint27.tmp: File exists Pull Request resolved: https://github.com/facebook/rocksdb/pull/6233 Test Plan: Run crash_test with high chance of checkpoint and make sure it doesn't reproduce. Differential Revision: D19207250 fbshipit-source-id: 12a931379e2e0572bb84aa658b6d03770c8551d4
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.
