How MVCC and Transactions Work in RocksDB
Summary
An in-depth technical explanation of how RocksDB implements MVCC through sequence numbers, snapshots, and versioning, including atomic write batches and transaction modes. It covers optimistic and pessimistic transactions, isolation levels, phantom reads, and a concrete transfer example, with code samples and diagrams illustrating the concepts. A valuable reference for developers integrating RocksDB transactions or evaluating MVCC in embeddable databases.
