Swan: Hybrid MVCC Management for Efficient Transaction Processing in LSM-Tree-Based Key-Value Stores
Summary: Swan hybridizes in-memory and out-of-memory MVCC, pairing fast visibility checks with low commit latency and memory use for large write transactions. Transaction-aware separation, an uncommitted-data stash, and concurrent memtable flushing adapt MVCC to LSM stores.
