Summary: Add request_id in IODebugContext which will be populated by underlying FileSystem for IOTracing purposes. Update IOTracer to trace request_id in the tracing records. Provided API IODebugContext::SetRequestId which will set the request_id and enable tracing for request_id. The API hides the implementation and underlying file system needs to call this API directly. Update DB::StartIOTrace API and remove redundant Env* from the argument as its not used and DB already has Env that is passed down to IOTracer. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8045 Test Plan: Update unit test.

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/
