[0035] Embodiment One

[0036] Figure 1 A flow chart of a data service device switching method according to an embodiment of the present application is provided, and the embodiment can be applicable to the case that the data service device switching efficiency is low and data loss easily occurs, resulting in low reading data accuracy. The method can be executed by a data service device switching apparatus, which can be realized in the form of hardware and / or software, and can be configured in an electronic device. As shown in the figure, the method comprises: Figure 1

[0037] ​S110, in response to the switching operation request of the data service device, determining a data service device to be switched.

[0038] The data service device to be switched can be a data device that is providing data support services and is ready to perform a device switching operation. Specifically, the data service device to be switched can be a data device that is currently providing data support services and needs to perform a device switching operation due to a device performance index value or a device failure condition. The device performance index value can include processing speed, storage capacity, and network bandwidth. The device failure can include excessively high downtime frequency and slow response speed.

[0039] Specifically, the data service device to be switched can be determined by parsing the switching operation request of the data service device to obtain a request parsing result. According to the request parsing result, the data device that needs to perform the device switching operation in the switching operation request is determined.

[0040] Optionally, before determining the data service device to be switched in response to the switching operation request of the data service device, the method further includes: determining the data service state of each data service device according to the service data of at least one data service device obtained through monitoring; and determining the data service device to be switched that meets the preset device switching condition according to the data service state of each data service device.

[0041] The service data can be the running state data of the data service device when providing data support services, and can specifically include performance data, service quality data, and log data. The performance data can include storage space occupancy, network throughput, and disk read speed. The service quality data can include response time, device running time, and data transmission delay data. The log data can include event logs such as device start-stop exceptions, operation logs, and security logs. The data service state can be used to evaluate whether the data support services provided by the data service device are running as expected, and can specifically include normal service and abnormal service. For example, if the occupancy rate of the storage space in the data service device is more than 90%, the data service state of the data service device can be considered abnormal. For example, if abnormal device start-stop data is obtained from the log data, such as ten times of device start-stop data within a week, the data service state of the data service device can be considered abnormal. The present embodiment does not make specific limitations.

[0042] The device switching condition can be specifically that whether to perform the device switching operation is determined according to the data service state of the data service device, for example, if the data service state is service exception, the device switching operation can be performed; if the data service state is service normal, the device switching operation can not be performed. Specifically, the service data of each data service device can be acquired, and the data service state of the data service device can be determined according to the acquired service data. According to the data service state, the data service device to be switched that needs to perform the device switching operation is determined.

[0043] The technical solution can determine the data service device to be switched that meets the device switching operation condition according to the data service state of the data service device, so that when the data service device fails, the data service device to be switched can be accurately found, the efficiency of the device switching of the data service device is greatly improved, and the accuracy and stability of the data service of the data service device are further improved.

[0044] S120, at least one candidate switching data service device in communication connection with the data service device to be switched is determined.

[0045] The candidate switching data service device can be a data device that supports performing the device switching operation. For example, if it is determined that the data service device to be switched is device A, the data service devices in communication connection with device A can include device A1, device A2 and device A3, device A1, device A2 and device A3 can be determined as the candidate switching data service device, and the embodiment is not limited specifically.

[0046] S130, the reference switching data service device is determined according to the first time stamp corresponding to the target storage data stored in each candidate switching data service device and meeting the preset recording time judgment condition.

[0047] The recording time judgment condition can be specifically that the execution recording time of the stored data in the data service device is judged to determine the execution recording time of the last stored data in the data service device. The first time stamp can be the execution recording time of the last stored data when at least one data is stored in the data service device, for example, the candidate switching data service device can include data a and data b, the time stamp corresponding to data a can be ten thirty twenty-five seconds, and the time stamp corresponding to data b can be eleven twenty ten seconds, data b can be determined as the last stored data, and the execution recording time of storing data b can be determined as the first time stamp.

[0048] The reference switching data service device can be a data device used to perform data support service after performing the device switching operation. Specifically, the execution record time of the last stored data in each candidate switching data service device can be obtained, and the execution record time of the last stored data in each candidate switching data service device can be obtained. Further, the reference switching data service device used to perform the device switching operation can be determined from each candidate switching data service device according to the execution record time of the last stored data.

[0049] Optionally, the reference switching data service device is determined according to the first timestamp corresponding to the target stored data in each candidate switching data service device that meets the preset record time judgment condition, including: performing consistency comparison on the first timestamp corresponding to the target stored data in each candidate switching data service device that meets the preset record time judgment condition, to obtain a consistency comparison result of the first timestamp; and determining the reference switching data service device from each candidate switching data service device according to the consistency comparison result of the first timestamp.

[0050] Specifically, the execution record time of the last stored data in each candidate data service device can be obtained, and the obtained execution record time can be compared for consistency to obtain a consistency comparison result of the execution record time. Further, the data device used to perform the device switching operation and provide data support service can be determined from each candidate switching data service device according to the consistency comparison result of the execution record time. For example, the candidate switching data service device corresponding to the data service device to be switched A can include candidate device A1, candidate device A2 and candidate device A3, wherein the first timestamp corresponding to the last stored data in candidate device A1 can be 11:25:08, the first timestamp corresponding to the last stored data in candidate device A2 can be 10:38:10, and the first timestamp corresponding to the last stored data in candidate device A3 can be 11:00:01. Candidate device A1 can be determined as the reference candidate data service device, which is not limited in the embodiment.

[0051] The technical solution can determine the reference switching data service device according to the first timestamp corresponding to the target stored data in each candidate switching data service device. The device switching operation is completed by the reference data service device, which improves the efficiency of the device switching operation of the data service device and the accuracy of the device operation.

[0052] S140, determining a target data update record meeting a record time judgment condition from a data record device storing a plurality of data update records.

[0053] The data update record can be operation record data generated when a data update operation is performed in the data service device. The data record device can be a device for storing operation record data generated by a data update operation. For example, data c and data d can be stored in the data service device. If data c is modified to data c1, a data update record can be generated in the data record device to record the data update operation of modifying data c to data c1.

[0054] The record time judgment condition can be a record time corresponding to a plurality of data update records stored in the data record device, and the record time of the latest data update record in the data record device can be determined. Specifically, at least one data update operation record stored in the data record device can be determined as the latest data update operation record in the data record device according to the record time of the at least one data update operation record, and the latest data update record can be determined as the target data update record. For example, as described in the above example, data c and data d can be stored in the data service device. If data c is modified to data c1 and data d is modified to data d1, a first data update record can be generated in the data record device to record the data update operation of modifying data c to data c1, and a second data update record can be generated in the data record device to record the data update operation of modifying data d to data d1. The record time of the first data update record can be 12:58:10, and the record time of the second data update record can be 12:30:15. The first data update record can be determined as the target data update record.

[0055] S150, determining whether to perform a data update on the reference switching data service device according to the first timestamp of the target stored data and the second timestamp of the target data update record, and determining the target switching data service device according to the determination result.

[0056] The second timestamp can be the record time of the latest data update record in the at least one data update record stored in the data record device.

[0057] The target switching data service device can be a data device for providing data payment services after a device update operation. Specifically, the execution record time of the last stored data in the reference switching data service device and the record time of the latest updated data record in the data record device can be compared to obtain a record time comparison result. According to the record time comparison result, it is determined whether the data update operation result of the last stored data in the reference switching data service device and the latest data update record in the data record device is the same, and the target switching data service device is determined according to the result.

[0058] S160, determining the target switching data service device as the target data service device to realize device switching of the data service device.

[0059] Specifically, the target switching data device can be determined as a data device providing data support service, and device switching operation is performed with the data service device to be switched, and data service is performed through the target switching data device, thereby completing device switching of the data service device.

[0060] Optionally, after determining the target switching data service device as the target data service device to achieve device switching of the data service device, the method further comprises: when receiving a data update request for the target data service device, determining to-be-updated data and target updated data according to the data update request; sending the data update request and a corresponding request time stamp to a data recording device, so that the data recording device generates a data update record corresponding to a data update operation result according to the received data update request and the corresponding request time stamp, and stores the data update record and the corresponding request time stamp in association, and feeds back an operation success instruction to the target data service device; and performing the data update request to update the to-be-updated data to the target updated data according to the operation success instruction.

[0061] The to-be-updated data can be data stored in the data service device for data support service. The target updated data can be data updated according to the data update operation on the data stored in the data service device. For example, the data service device can store data e, and the data update operation can update the data e to e1, so the data e can be determined as the to-be-updated data, and the data e1 can be determined as the target updated data.

[0062] The data update request can be an operation request for updating the data stored in the data service device. The request time stamp can be an event of initiating the operation request for updating the stored data. Specifically, when receiving the operation request for updating the data stored in the data service device, the data to be updated in the data service device and the updated data are determined according to the operation request. Then, the operation request and the corresponding request initiation time are sent to the data recording device. The data recording device generates a data update record corresponding to the operation request according to the operation request, and stores the data update record and the corresponding time stamp in association. After successful storage, the data recording device sends prompt information of operation success to the data service device. According to the prompt information of operation success, the to-be-updated data is updated to the target updated data.

[0063] The technical scheme can send a data update operation request and a corresponding time stamp to a data recording device according to an update operation request for stored data in a data service device, to generate a data update record in the data recording device and store the data update record in association with the corresponding time stamp, and to further implement data update operation for the stored data in the data service device. Data loss during device switching is avoided, and the reliability of data in the data service device is improved.

[0064] The technical scheme of the embodiment of the application can determine a to-be-switched data service device in response to a switching operation request for a data service device, determine at least one candidate switched data service device in communication connection with the to-be-switched data service device, determine a reference switched data service device according to a first time stamp corresponding to target stored data in each candidate switched data service device that meets a preset record time judgment condition, determine a target data update record that meets the record time judgment condition from a data recording device storing a plurality of data update records, judge whether to perform data update on the reference switched data service device according to the first time stamp of the target stored data and the second time stamp of the target data update record, determine a target switched data service device according to a judgment result, and determine the target switched data service device as a target data service device to implement device switching of the data service device. The technical scheme can determine a to-be-switched data service device and at least one candidate switched data service device of the to-be-switched data service device according to a switching operation request for a data service device. Further, the target switched data service device is determined according to the first time stamp of the target stored data in each candidate switched data service device and the second time stamp of the target update record in the data recording device, the target switched data service device is determined as the target data service device, the efficiency of device switching operation of the data service device is improved, data loss during device switching is avoided, and the reliability of data in the data service device is improved.

[0065] Optionally, the target switched data service device is determined according to a judgment result of whether to perform data update on the reference switched data service device according to the first time stamp of the target stored data and the second time stamp of the target data update record, including: performing consistency comparison on the first time stamp of the target stored data and the second time stamp of the target data update record to obtain a consistency comparison result; if the consistency comparison result is time stamp consistent, no data update is needed for the reference switched data service device, and the reference switched data service device is determined as the target switched data service device.

[0066] Specifically, the first timestamp of the target stored data in the data service device and the second timestamp of the target data update record are compared for consistency, and a consistency comparison result of the timestamps is obtained, so as to determine whether the data update result corresponding to the target stored data in the data service device and the target data update record in the data record device is consistent, and when the consistency comparison result of the timestamps is consistent, it can be determined that the data update result of the reference switching data service device and the target data update record in the data record device is consistent, that is, it can be determined that the reference switching data service device and the target stored data in the to-be-switched data service device are consistent, and there is no need to perform data update operation on the reference switching data service device, and the reference switching data service device can be directly determined as the target switching data service device.

[0067] According to the technical scheme, the first timestamp of the target stored data and the second timestamp of the target data update record are compared for consistency, and when the consistency comparison result is that the timestamps are consistent, the reference switching data service device can be determined as the target switching data service device, so that data loss during device switching is avoided, and the reliability of data in the data service device is improved.

[0068] Embodiment two

[0069] Figure 2 A flowchart of a data service device switching method provided by the second embodiment of the present application is shown in the figure. Based on the above-mentioned embodiments, the data service device switching method is further optimized in the present embodiment.

[0070] Further, the step of "determining whether to perform data update on the reference switching data service device according to the first timestamp of the target stored data and the second timestamp of the target data update record, and determining the target switching data service device according to the determination result" is refined as "comparing the first timestamp of the target stored data and the second timestamp of the target data update record for consistency, and obtaining a consistency comparison result; if the consistency comparison result is that the timestamps are inconsistent, determining the reference data update record in the data record device that meets the data update condition according to the first timestamp of the target stored data; performing data update on the stored data in the reference switching data service device according to the reference data update record, and determining the updated reference switching data service device as the target switching data service device." to improve the generation mode of the user access permission list. As shown in the figure, the method comprises the following steps. Figure 2

[0071] S210, in response to a switching operation request of a data service device, determining a to-be-switched data service device.

[0072] S220, determining at least one candidate switching data service device in communication connection with the to-be-switched data service device. ​

[0073] S230, determining the reference data service device according to the first timestamp corresponding to the target stored data satisfying the preset recording time judgment condition stored in each candidate data service device.

[0074] S240, determining the target data update record satisfying the recording time judgment condition from the data record device storing a plurality of data update records.

[0075] S250, performing consistency comparison between the first timestamp of the target stored data and the second timestamp of the target data update record to obtain a consistency comparison result.

[0076] The target stored data can be the last stored data in at least one data stored in the data service device. The target data update record can be the latest data update record in at least one data update record stored in the data record. Specifically, the first timestamp of the target stored data can be compared with the second timestamp of the target update record for consistency comparison, and a consistency comparison result can be obtained. For example, the first timestamp of the target stored data can be timestamp M1, and the second timestamp of the target update record can be timestamp M2. The consistency comparison between timestamp M1 and timestamp M2 can be performed, and a consistency comparison result of the timestamp can be obtained.

[0077] S260, if the consistency comparison result is that the timestamps are inconsistent, determining the reference data update record satisfying the data update condition in the data record device according to the first timestamp of the target stored data.

[0078] The reference data update record can be a data update record stored in the data record device and not recorded in the data service device. Specifically, when the consistency comparison result of the timestamp is that the timestamps are inconsistent, the first timestamp and the second timestamp between the data update records stored can be determined as the reference data update record according to the first timestamp. For example, if the consistency comparison result is that timestamp M1 and timestamp M2 are inconsistent, it indicates that the data update operation corresponding to the data update record stored in the data record device has not been executed in the reference data service device, and further, the data update record between timestamp M1 and timestamp M2 can be determined as the reference data update record.

[0079] S270, performing data update on the stored data in the reference data service device according to the reference data update record, and determining the updated reference data service device as the target data service device.

[0080] Specifically, the data update operation corresponding to the obtained reference data update record can be used to update the corresponding stored data in the reference switching data service device, and the updated reference switching data service device is determined as the target switching data service device. For example, if there are two data update records between the timestamp M1 and the timestamp M2, such as data f is updated to f1 and data g is deleted, the two data update records can be determined as the reference data update records, and the data f in the reference switching data service device is updated to f1 and the data g is deleted according to the data update records. Further, the updated reference switching data service device can be determined as the target switching data service device, which is not limited in the embodiment.

[0081] In S280, the target switching data service device is determined as the target data service device to realize the device switching of the data service device.

[0082] The technical scheme of the embodiment of the application comprises the following steps: in response to a switching operation request of a data service device, a to-be-switched data service device is determined; at least one candidate switching data service device in communication connection with the to-be-switched data service device is determined; a reference switching data service device is determined according to a first timestamp corresponding to target stored data in each candidate switching data service device that satisfies a preset record time judgment condition; a target data update record satisfying the record time judgment condition is determined from a data record device storing a plurality of data update records; whether the reference switching data service device is updated is judged according to the first timestamp of the target stored data and the second timestamp of the target data update record, and the target switching data service device is determined according to the judgment result; and the target switching data service device is determined as the target data service device to realize the device switching of the data service device. The technical scheme can determine the to-be-switched data service device and at least one candidate switching data service device of the to-be-switched data service device according to the switching operation request of the data service device. Further, the target switching data service device is determined according to the first timestamp of the target stored data in each candidate switching data service device and the second timestamp of the target update record in the data record device, and the target switching data service device is determined as the target data service device, which improves the efficiency of the device switching operation of the data service device and avoids data loss during device switching, and improves the reliability of the data in the data service device.
