Summary: 1. Move kUniversalSubcompactions up before kEnd in db_test_util.h, so tests that cycle through all the option_configs include this 2. Skip kUniversalSubcompactions wherever kUniversalCompaction and kUniversalCompactionMultilevel are skipped Related to #3935 Pull Request resolved: https://github.com/facebook/rocksdb/pull/4125 Differential Revision: D8828637 Pulled By: anand1976 fbshipit-source-id: 650dee15fd27d85281cf9bb4ca8ab460e04cac6f
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.
