Summary: We temporarily disabled WAL when Remote Compaction is enabled in Stress Test (https://github.com/facebook/rocksdb/pull/13843). There are few others to incompatible features when WAL is disabled. Due to the sanitization order, WAL was disabled at the end of the sanitization and these incompatible features weren't set properly. Stress Test failed with an error like the following. e.g. `reopen` stress test is not compatible with `disable_wal` - `Error: Db cannot reopen safely with disable_wal set!` This PR changes the order of sanitization so that `disable_wal` is set earlier when `remote_compaction_worker_threads > 0` Pull Request resolved: https://github.com/facebook/rocksdb/pull/13845 Test Plan: ``` python3 -u tools/db_crashtest.py blackbox --remote_compaction_worker_threads=8 --interval=5 --duration=6000 --continuous_verification_interval=10 --disable_wal=1 --use_txn=1 --txn_write_policy=2 --enable_pipelined_write=0 --checkpoint_one_in=0 --use_timed_put_one_in=0 ``` Reviewed By: cbi42 Differential Revision: D79758670 Pulled By: jaykorean fbshipit-source-id: aa6f4a74cc86c23f442928c301187b06e8137f53
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.
