Definitions
- the present invention relates to the field of communications technologies, and in particular, to a data processing method, and to a data processing device.
- streaming computing can calculate the dynamically generated data in real time and feed back the results in time.
- streaming computing has been widely used in financial banking applications, Internet applications, and Internet of Things applications. It is mainly used to collect statistics on data within a certain time interval, that is, to perform statistics on data within a predetermined time window.
- time window in the flow calculation is divided into two types: “system time window” and “data time window”, and their respective characteristics and disadvantages are as follows:
- the system time window counts the data of the data generation end based on the system time. First, the statistical time of the data is divided into multiple system time windows according to a preset time interval, and then the system time window statistical result is output. If the data is processed only according to the system time window, the data has a certain delay from the generating end to the statistical end, and the data processed in the system time window is often not equal to the generated value generated by the generating end in the preset time interval. Data, which makes the results of streaming calculations affected.
- the data time window counts the data at the data generation end based on the data time.
- the data time of the data received by the statistics terminal is not necessarily strictly increased according to the order of the data time. Therefore, the problem of data out of order occurs in the statistical results based on the data time window. In the actual statistical process, it is easy to appear that the edge of the current data time window will have some data spanning into another data time window, so that the result of the streaming calculation is affected.
- the accuracy of the streaming calculation can be guaranteed only by ensuring that all data of the current data time window reaches the statistical end. Therefore, the current actual statistical process only closes the current data time when the data received by the statistical terminal exceeds the data time window and reaches the preset value, or the data received by the statistical terminal reaches the preset number in the next data time window. window.
- the data of the flow calculation is usually unstable. When the amount of data of a certain statistical item is small, the data of the next data time window has not reached the statistical end, and the statistical result of the current data time window is not output in time, resulting in data. Statistical delays have affected the results of streaming calculations.
- the invention provides a data processing method, which solves the problem that the statistical data is complete and the statistical data processing in real time cannot be balanced by setting the closing time point and the synchronization time point for each system time window of the data statistics system in advance. problem.
- the method is applied to a data statistics system, wherein each segment of the system time window of the data statistics system is preset with a closing time point and a synchronization time point, the closing time point is before the synchronization time point, and is located in the After the start time point of the system time window, the method includes:
- the system receiving time is in the The data to be processed before the synchronization time point is cached, and the data to be processed after the synchronization time point of the system reception time is processed immediately;
- the pending data of the system receiving time before the closing time point is processed immediately, and the system receiving time is at the closing time point.
- the pending data is discarded.
- determining a system time window corresponding to the to-be-processed data according to the data time of the to-be-processed data specifically:
- the method further includes:
- the method further includes:
- the closing time point is set according to a time difference between the system time and the data time
- the synchronization time point is set according to the time consumption of the closing time window and the clock difference between the devices in the data statistics system.

- a determining module when receiving data to be processed in the current system time window, determining a system time window corresponding to the to-be-processed data according to the data time of the to-be-processed data;
- a first processing module in the data time period, within a current system time window, buffering data to be processed before the synchronization time point of the system receiving time, and receiving the system receiving time at the synchronization time point
- the pending data is processed immediately;
- a second processing module when the data time is within a range of a previous system time window, processing the to-be-processed data of the system receiving time before the closing time point, and receiving the system receiving time The data to be processed after the closing time point is discarded.
- the determining module is specifically configured to:
- the device further includes:
- a first output module when the system time of the data statistics system reaches the closing time point, outputting a processing result of the data to be processed whose data time is within the range of the previous system time window, and closing the The data time window corresponding to the previous system time window.
- the device further includes:
- a second output module when the system time of the data statistics system reaches the synchronization time point, processing data to be processed that is buffered before the synchronization time point and whose data time is within a current system time window range, and Output processing results.

- FIG. 2 is a schematic flow chart of a data processing method according to a specific embodiment of the present application.
- FIG. 3 is a schematic structural diagram of a data processing device according to the present application.
- the present application provides a data processing method, by setting a closing time point and a synchronization time point in each system time window, and treating the data to be processed by using the closing time point and the synchronization time point as nodes. Segmentation processing and output effectively improve the accuracy and real-time performance of data processing results.

- the synchronization time point is the end synchronization time of the data time window corresponding to the current system time window. Therefore, the system time window is divided into different processing and output stages by using the closing time point and the synchronization time point as nodes, and the real-time performance of the processing result output can be ensured while ensuring the integrity of the data processing.
- the closing time point is set according to a time difference between the system time and the data time

- the closing time point of the same system time window is before the synchronization time point and after the starting time point, the method comprising the steps of:
- the data time of the data to be processed by the data statistics system is not necessarily strictly increased according to the order of the data time, because the clock difference of the device at the data generating end and the speed of the data transmission process are affected. Therefore, it is easy for the pending data belonging to the previous system time window to cross the current system time window. That is to say, in the data to be processed received by the current system time window, there may be some data to be processed corresponding to the previous system time window. This will not only affect the integrity of the data in the previous system time window, but also interfere with the data processing of the current system time window.

- the data type with a timestamp of 10:04 may arrive in the system time window of 1 ⁇ 2min. This will not only affect the integrity of the data processing of the system time window from 0 to 1 min, but also interfere with the data processing of the system time window of 1 to 2 minutes.
- the system time window corresponding to the data to be processed needs to be determined according to the data time of the data to be processed, and the specific determination process is as follows:
