This article explains how RocksDB implements Multi-Version Concurrency Control (MVCC) and transactions by leveraging its underlying LSM-tree architecture, which naturally creates new key versions on every write. It details how snapshots provide consistent read views without blocking writers, avoiding the performance bottlenecks associated with traditional locking mechanisms.
Background
RocksDB is a high-performance embedded key-value store widely used in distributed systems like TiKV and CockroachDB. Understanding its internal concurrency control mechanisms is crucial for optimizing database performance and ensuring data consistency.
