Summary: Hello from a happy user of rocksdb java :-) Default constructor of TraceOptions is supposed to initialize size to 64GB but the expression contains an integer overflow. Simple test case with JShell: ``` jshell> 64 * 1024 * 1024 * 1024 $1 ==> 0 jshell> 64L * 1024 * 1024 * 1024 $2 ==> 68719476736 ``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/9157 Reviewed By: pdillinger, zhichao-cao Differential Revision: D32369273 Pulled By: mrambacher fbshipit-source-id: 6a0c95fff7a91f27ff15d65b662c6b101756b450
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.
