ZenFS+: Nurturing Performance and Isolation to ZenFS
This paper proposes ZenFS+, a new storage backend of RocksDB for small-zone ZNS SSD.RocksDB has complicated internal operations such as flush and compaction.Flush and compaction run in separate threads, and it is well known that they closely interact around the sstables.Due to the concurrent storage I/O between flush and compaction, ZenFS pr
