| This document introduces the principles of TiDB's optimistic transaction model and related features. | ||
|
|
||
| In TiDB's optimistic transaction model, the two-phase commit begins right after the client executes the `COMMIT` statement. Therefore, the write-write conflict can be observed before the transactions are actually committed. | ||
| TiDB uses the optimistic transaction model by default. In TiDB's optimistic transaction model, the two-phase commit begins only after the transaction is committed. |
