Summary: Concurrent memtable adds were incorrectly computing the last sequence number for a write batch group when the write batches were not solitary. This is the cause of https://github.com/facebook/mysql-5.6/issues/155 Test Plan: 1. unit tests 2. new unit test 3. parallel db_bench stress tests with batch size of 10 and asserts enabled Reviewers: igor, sdong Reviewed By: sdong Subscribers: IslamAbdelRahman, MarkCallaghan, dhruba Differential Revision: https://reviews.facebook.net/D53595
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.
