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

A computer device, comprising a processor and a memory, the memory storing at least one instruction, the at least one instruction being loaded and executed by the processor to perform a plurality of operations comprising:

• receiving, from a receiving buffer, at least one piece of historical state data transmitted by a node device, the receiving buffer being configured for caching received historical state data;
• adding the at least one piece of historical state data in the receiving buffer to a forwarding buffer, and converting, by using the forwarding buffer, the at least one piece of historical state data into data meeting a tuple format, to obtain at least one data item, the forwarding buffer being configured for performing data format conversion on historical state data;
• and
• storing the at least one data item in at least one target data table of a cluster database, one target data table being corresponding to one original data table in which one data item is located in the node device.

A non-transitory computer-readable storage medium, storing at least one instruction, the at least one instruction being loaded and executed by a processor of a computer device to perform a plurality of operations comprising:

• receiving, from a receiving buffer, at least one piece of historical state data transmitted by a node device, the receiving buffer being configured for caching received historical state data;
• adding the at least one piece of historical state data in the receiving buffer to a forwarding buffer, and converting, by using the forwarding buffer, the at least one piece of historical state data into data meeting a tuple format, to obtain at least one data item, the forwarding buffer being configured for performing data format conversion on historical state data;
• and
• storing the at least one data item in at least one target data table of a cluster database, one target data table being corresponding to one original data table in which one data item is located in the node device.
