Jim Meyering b3fd162267 build: remove unportable use of sed in favor of $(CXX)'s -MT Summary: The code being removed would invoke sed differently to work around a portability difference in how sed -i works (different on MacOS). Yet performing a host-type-based ifdef fails when the tools installed do not match. That sed use was solely to post-process the .d file. Instead, generate the desired output directly, by using the compiler's -MT<FILE> option. * Makefile (%.d: %.cc): With the prior use of Makefile-ifdef'd sed, when building on MacOS with gnu sed, every run of this rule would fail with a sed usage error. Also list each .d file as a dependent. Test Plan: Ensure that a selected .d file is the same as before both with g++ and with clang++. However, note that the new .d files each contain a new reference to the .d file itself.

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.

Start with example usage here: https://github.com/facebook/rocksdb/tree/master/examples

See the github wiki for more explanation.

The public interface is in include/. Callers should not include or rely on the details of any other header files in this package. Those internal APIs may be changed without warning.

Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/
