Summary: If compaction job needs to be aborted inside `Schedule()` or `Wait()` today (e.g. Primary host is shutting down), the only two options are the following - Handle it as failure by returning `CompactionServiceJobStatus::kFailure` - Return `CompactionServiceJobStatus::kUseLocal` and let the compaction move on locally and eventually succeed or fail depending on the timing In this PR, we are introducing a new status, `CompactionServiceJobStatus::kAborted`, so that the implementation of `Schedule()` and `Wait()` can return it. Just like how `CompactionServiceJobStatus::kFailure` is handled, compaction will not move on and fail, but the status will be returned as `Status::Aborted()` instead of `Status::Incomplete()` Pull Request resolved: https://github.com/facebook/rocksdb/pull/13438 Test Plan: Unit Test added ``` ./compaction_service_test --gtest_filter="*CompactionServiceTest.AbortedWhileWait*" ``` Reviewed By: anand1976, hx235 Differential Revision: D70655355 Pulled By: jaykorean fbshipit-source-id: 22614ce9c7455cda649b15465625edc93978fe11
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.
