Summary: Expose the inverse of ToString(hex=true) on Slice: Slice::DecodeHex Refactor the other implementation of to/from hex in ldb_cmd.h to use the Slice version (Difference between the 2 is whether 0x is expected/produced in front of the hex string or not) Eliminated support for invalid odd length hex string - this is now invalid instead of having 1/2 byte set Added (inverse of HexToString) test for LDBCommand::StringToHex which also indirectly tests Slice::ToString(true) After moving the original implementation from ldb_cmd.h, updated it to much simpler/efficient version (originally/inspired from https://github.com/facebook/wdt/blob/master/util/EncryptionUtils.cpp#L140-L169 ) Test Plan: run tests Reviewers: uddipta, sdong Reviewed By: sdong Subscribers: andrewkr, dhruba Differential Revision: https://reviews.facebook.net/D56121
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.
