Summary: We see a failure of obsolete_files_test but aren't able to identify the issue. Improve the test in following way and hope we can debug better next time: 1. Place sync point before automatic compaction runs so race condition will always trigger. 2. Disable sync point before test finishes. 3. ASSERT_OK() instead of ASSERT_TRUE(status.ok()) Pull Request resolved: https://github.com/facebook/rocksdb/pull/5125 Differential Revision: D14669456 Pulled By: siying fbshipit-source-id: dccb7648e334501ad651eb212880096eef1f4ab2
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 specially suitable for storing multiple terabytes of data in a single database.
