Summary: The current build is failing on some platforms due to an __unused__ attribute. This patch prevents the problem by using a pattern similar to MergeHelper (assert not on the variable but inside a condition that uses the variable). We should have better error handling in both cases in the future. Test Plan: make clean all check Reviewers: rven, anthony, yhchiang, sdong, igor, aekmekji Reviewed By: aekmekji Subscribers: dhruba, leveldb Differential Revision: https://reviews.facebook.net/D46623
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.
