transactional key-value database, TiKV provides transactional interfaces with ACID compliance, and guarantees data consistency between multiple replicas and high availability with the implementation of the OPTIMISTIC. After that, you can either commit (COMMIT) or roll back (ROLLBACK) the transaction. TiDB guarantees atomicity for all statements between the start of BEGIN and the end of COMMIT or ROLLBACK, that additional operations when in- serting data. There is no additional insertion logic. TiDB automatically guarantees data consistency. All you need to do is turn on column-oriented replica synchronization after creating

transactional key-value database, TiKV provides transactional interfaces with ACID compliance, and guarantees data consistency between multiple replicas and high availability with the implementation of the stored in multiple stores at the same time according to the replica rules defined by users. This guarantees that data is still readable and writable even if a single or a few stores are temporarily offline database TiDB natively supports the three-DC-in-two-city architecture by using the Raft algorithm, and guarantees the consistency and high availability of data within a database cluster. Because the network latency
