Summary: 1. As part of IOTracing project, Add a class IOTracer, IOTraceReader and IOTracerWriter that writes the file operations information in a binary file. IOTrace Record contains record information and right now it contains access_timestamp, file_operation, file_name, io_status, len, offset and later other options will be added when file system APIs will be call IOTracer. 2. Add few unit test cases that verify that reading and writing to a IO Trace file is working properly and before start trace and after ending trace nothing is added to the binary file. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6958 Test Plan: 1. make check -j64 2. New testcases for IOTracer.

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.
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/ and https://rocksdb.slack.com/
