Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for implementing a hybrid database. In an example method, a system receives an indication to process a data request. The system is configured as a hybrid database to dynamically switch between a stand-alone mode and a distributed mode. When the indication indicates to the system to process the data request in the stand-alone mode, the system switches the hybrid database to the stand-alone mode and processes the data request in the stand-alone mode. When the indication indicates to the system to process the data request in the distributed mode, the system switches the hybrid database to the distributed mode and processes the data request in the distributed mode.

Hybrid database implementations

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for transaction processing. In an example method, a system receives a first transaction. The system is configured as a hybrid database to dynamically switch between a stand-alone mode and a distributed mode. The system determines whether the first transaction is a stand-alone type of transaction or a distributed type of transaction. In response to determining that the first transaction is a stand-alone type of transaction, the system performs one or more operations of the first transaction in the stand-alone mode. In response to determining that the first transaction is a distributed type of transaction, the system performs one or more operations of the first transaction in the distributed mode.

Embodiments of the present specification provide a method for updating a database by using a two-phase commit distributed transaction. The method is applied to a coordinator, and includes: sending a first-phase prepare request message to each participant to end a current transaction, the current transaction being configured to update a target database record; and after receiving write lock advance release requests sent by all participants, returning a write lock advance release response to each participant to instruct each participant to unlock a target database record of the participant, the write lock advance release requests being sent by the participants after the participants successfully write a log of an update operation of the current transaction to a log buffer.
