TiKV Deep Dive: TiKV Read Write

TiKV is the backbone of TiDB's transactional layer. This essential module is broken into four parts, covering how TiDB achieves strong consistency and massive-scale OLTP: 1. Persistent Storage: Explore the use of RocksDB, an LSM-tree-based key-value store, for efficient data persistence. 2. Distributed Transactions: Understand the 2-phase commit protocol based on Google’s Percolator model, supporting both optimistic and pessimistic locking. 3. Strong Consistency (Raft): Learn how the Raft consensus algorithm and Regions (the basic data distribution unit, max 96MB) ensure fault tolerance and high availability with three replicas by default. 4. MVCC and Coprocessor: Discover how Multi-Version Concurrency Control (MVCC) enables highly concurrent reads/writes and how the Coprocessor pushes down filtering and aggregation operations to the storage layer for massive performance gains. Key Concepts Covered: TiKV, RocksDB, LSM Tree, Distributed Transaction, Raft Consensus, MVCC, Coprocessor. #TiKV #Raft #MVCC #DistributedTransaction #NoSQL #Key-Value
