Summary: Run the basic range deletion tests against the standard set of configurations. This testing exposed that files with hash indexes and partitioned indexes were not handling the case where the file contained only range deletions--i.e., where the index was empty. Additionally file a TODO about the fact that range deletions are broken when allow_mmap_reads = true is set. /cc ajkr nvanbenschoten Best viewed with ?w=1: https://github.com/facebook/rocksdb/pull/4021/files?w=1 Pull Request resolved: https://github.com/facebook/rocksdb/pull/4021 Differential Revision: D8811860 Pulled By: ajkr fbshipit-source-id: 3cc07e6d6210a2a00b932866481b3d5c59775343
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.
