Transaction Processing Method and Apparatus, and Computer System

A computer system, comprising:

• a non-volatile memory configured to store data;
• and
• a processor coupled to the non-volatile memory and configured to:
• receive a transaction processing request, wherein the transaction processing request carries transaction data of a transaction;
• record status information of the transaction in the non-volatile memory, wherein the status information of the transaction comprises a transaction status, a transaction identifier, and an address that are each allocated to the transaction according to the transaction processing request, wherein the transaction status is an uncommitted state, and wherein the uncommitted state indicates that not all the transaction data is written to the non-volatile memory;
• write the transaction data to the non-volatile memory according to the address;
• modify the transaction status of the transaction to a committed state according to the transaction identifier, wherein the committed state indicates that all the transaction data of the transaction is written to the non-volatile memory, and not all the transaction data is written to an external memory of the computer system;
• write the transaction data to the external memory of the computer system from the non-volatile memory;
• and
• modify the transaction status of the transaction to a backup state according to the transaction identifier, wherein the backup state indicates that all the transaction data of the transaction is written to the external memory of the computer system.

A computer program product comprising one or more computer-executable instructions, wherein the one or more computer-executable instructions, when executed on a processor of a computer system, cause the computer system to carry out:

• receiving a transaction processing request, wherein the transaction processing request carries transaction data of a transaction;
• recording status information of the transaction in the non-volatile memory, wherein the status information of the transaction comprises a transaction status, a transaction identifier, and an address that are allocated to the transaction according to the transaction processing request, wherein the transaction status is an uncommitted state, and wherein the uncommitted state indicates that not all the transaction data is written to the non-volatile memory;
• writing the transaction data to the non-volatile memory according to the address;
• modifying the transaction status of the transaction to a committed state according to the transaction identifier, wherein the committed state indicates that all the transaction data of the transaction is written to the non-volatile memory and not all the transaction data is written to an external memory of the computer system;
• writing the transaction data to the external memory of the computer system from the non-volatile memory;
• and
• modifying the transaction status of the transaction to a backup state according to the transaction identifier, wherein the backup state indicates that all the transaction data of the transaction is written to the external memory of the computer system.
