Summary: The designed sync point may not be hit if trash file is generated faster than deleting. Then the file will be deleted directly instead of waiting for background trash empty thread to do it. Increase SstFileManager Trash/DB ratio to avoid that. Pull Request resolved: https://github.com/facebook/rocksdb/pull/9706 Test Plan: `gtest-parallel ./delete_scheduler_test --gtest_filter=DeleteSchedulerTest.StartBGEmptyTrashMultipleTimes -r 10000 -w 100` It was likely to happen on one of the host.

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.
