sdong 12117b26a3 Fix flaky DBTest2.RateLimitedCompactionReads (#9185)
Summary:
DBTest2.RateLimitedCompactionReads sometime shows following failure:

  what():  db/db_test2.cc:3976: Failure
Expected equality of these values:
  i + 1
    Which is: 4
  NumTableFilesAtLevel(0)
    Which is: 0

The assertion itself doesn't appear to be correct. Fix it.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9185

Test Plan: Removing an assertion shouldn't break anything.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

CircleCI Status TravisCI Status Appveyor Build status PPC64le Build Status

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/main/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/
