A data processing method is provided. The method includes obtaining an operation instruction, the operation instruction including operation type information and target data unit information corresponding to a target data unit; querying a target data group in a data group set according to the target data unit information, the data group set including at least one data group, the data group including at least one data unit; obtaining locked-state information of the target data group; performing locking detection on the target data unit based on the locked-state information and the operation type information to obtain a detection result; performing locking processing on the target data unit based on the detection result; and executing the operation instruction after the locking processing is performed, to perform an operation corresponding to the operation type information on the target data unit.

Data processing method and related apparatus

In a data read method a plurality of tuples meeting a read condition are determined in a case that the data read request is received and according to a read condition carried in the data read request. Global transaction statuses of a plurality of global transactions corresponding to the plurality of tuples are obtained. Global commit times of the plurality of global transactions according to the global transaction statuses of the plurality of global transactions are obtained. Then a target tuple from the plurality of tuples is determined based on the global commit times of the plurality of global transactions, the target tuple being visible relative to the data read request.

Data read method and apparatus, computer device, and storage medium

This application discloses a data storage method and associated server, and a non-transitory computer readable storage medium, and belongs to the field of data processing technologies. The method includes: determining historical-state data of a to-be-dumped data item from a database, and determining a service requirement of the historical-state data; determining a target storage format of the historical-state data according to the service requirement; and dumping the historical-state data according to the target storage format.
