Distributed database transaction processing method, device based on GPS atomic clock server

A distributed database transaction processing device for use at a first node server, comprising:

• one or more processors;
• and
• a storage device configured for storing one or more programs, wherein
• the one or more programs are executed by the one or more processors to enable the one or more processors to implement a method comprising:
• receiving a plurality of transaction requests issued from one or more second node servers, each of the one or more second node servers having a local time synchronized with a time of a Global Positioning System (GPS) atomic clock server in an area where the second node server is located;
• determining a set of conflicting transactions by detecting a concurrency conflict among transactions corresponding to the plurality of received transaction requests;
• obtaining a start time of each of conflicting transactions among which the concurrency conflict is determined, wherein the start time is the local time of the second node server that issued the transaction request corresponding to the conflicting transaction at the time that the transaction request was issued;
• and
• processing the conflicting transactions in a time order of the start time of each of the conflicting transactions.

A non-transitory computer-readable storage medium in which a computer program is stored, the computer program, when executed by a processor, causing the processor to execute a method comprising:

• receiving a plurality of transaction requests issued from one or more second node servers, each of the one or more second node servers having a local time synchronized with a time of a Global Positioning System (GPS) atomic clock server in an area where the second node server is located;
• determining a plurality of conflicting transactions by detecting concurrency conflicts among transactions corresponding to the plurality of received transaction requests;
• obtaining a start time of each of the plurality of conflicting transactions, wherein the start time is the local time of the second node server that issued the transaction request corresponding to the conflicting transaction at the time that the transaction request was issued;
• and
• processing the conflicting transactions in a time order of the start times of the conflicting transactions.
