Summary: Context: As need for new feature of resource management using RocksDB's rate limiter like [https://github.com/facebook/rocksdb/issues/8595](https://github.com/facebook/rocksdb/pull/8595) arises, it is about time to re-learn our rate limiter and make this learning process easier for others by improving its readability. The comment/assertion/one extra else-branch are added based on my best understanding toward the rate_limiter.cc and rate_limiter_test.cc up to date after giving it a hard read. - Add code comments/assertion/one extra else-branch (that is not affecting existing behavior, see PR comment) to describe how leader-election works under multi-thread settings in GenericRateLimiter::Request() - Add code comments to describe a non-obvious trick during clean-up of rate limiter destructor - Add code comments to explain more about the starvation being fixed in GenericRateLimiter::Refill() through partial byte-granting - Add code comments to the rate limiter's setup in a complicated unit test in rate_limiter_test Pull Request resolved: https://github.com/facebook/rocksdb/pull/8596 Test Plan: - passed existing rate_limiter_test.cc Reviewed By: ajkr Differential Revision: D29982590 Pulled By: hx235 fbshipit-source-id: c3592986bb5b0c90d8229fe44f425251ec7e8a0a |
