Fig. 1-2 are schematic diagrams of an application scenario of a data synchronization method according to some embodiments of the present disclosure.
In the application scenario of fig. 1, first, the computing device 101 may generate a task key-value pair 103 of the target data synchronization task in response to receiving the parameter information 102 of the target data synchronization task. The parameter information 102 may include source database address information 104 of a source database corresponding to the target data synchronization task, target database address information 105 of a target database corresponding to the target data synchronization task, and a synchronization type 106. For example, the source database address information 104 may be IP address information of the source database. The target database address information 105 may be IP address information of the target database. Then, the computing device 101 may select an execution node from the execution node cluster 107 as the target execution node 108 according to the health of each execution node in the execution node cluster 107 in response to the execution state information included in the value of the pre-parent task key value pair of the task key value pair 103 representing the completion of execution. The target execution node 108 may be configured to, in response to that the connection status of the source database is a connected status, send a data synchronization operation statement generated according to the source database address information 104 and the synchronization type 106 to the target database based on the target database address information 105. The target database may be used to execute the data synchronization operation statement.
Alternatively, as shown in fig. 2, first, the computing device 101 may obtain the data volume of the data obtained by each execution node in the execution node cluster 107 from the corresponding source database and obtain the speed of the data, and obtain a data volume set 109 and a speed set 110. Then, the computing device 101 may control the associated second warning device 111 to perform the second warning operation in response to the presence of the data amount satisfying the abnormal data amount condition in the above-described data amount set 109 or the presence of the speed satisfying the abnormal speed condition in the above-described speed set 110. For example, the second alarm device 111 may be an alarm having a function of playing audio.
The computing device 101 may be hardware or software. When the computing device is hardware, it may be implemented as a distributed cluster composed of multiple servers or terminal devices, or may be implemented as a single server or a single terminal device. When the computing device is embodied as software, it may be installed in the hardware devices enumerated above. It may be implemented, for example, as multiple software or software modules to provide distributed services, or as a single software or software module. And is not particularly limited herein.
It should be understood that the number of computing devices in fig. 1-2 is merely illustrative. There may be any number of computing devices, as implementation needs dictate.
With continued reference to fig. 3, a flow 300 of some embodiments of a data synchronization method according to the present disclosure is shown. The data synchronization method comprises the following steps:
In some embodiments, an executing agent of the data synchronization method (e.g., computing device 101 shown in fig. 1) may generate a task key-value pair for a target data synchronization task in response to receiving parameter information for the target data synchronization task. The target data synchronization task may be a data synchronization task corresponding to currently received parameter information. The task key-value pair may be a key-value pair for recording relevant information of a corresponding data synchronization task. The value of the task key value pair may include execution state information of the target data synchronization task. The key of the task key value pair may be an identifier of the corresponding data synchronization task. The execution status information may be status information of an execution progress of the corresponding data synchronization task. For example, the execution status information may be "completed", indicating that the corresponding data synchronization task has been executed and completed. For another example, the execution state information may also be "to be completed", which indicates that the corresponding data synchronization task is not executed and completed. For another example, the execution state information may be "in execution" to indicate that the corresponding data synchronization task is being executed. The parameter information may include source database address information of a source database corresponding to the target data synchronization task, target database address information of a target database corresponding to the target data synchronization task, and a synchronization type. The source database may be a database that needs to be backed up. The source database address information may be IP address information of the source database. The target database may be a database for storing data that needs to be backed up in the source database. The destination database address information may be IP address information of the destination database. The synchronization type may be a type of a synchronization manner of the target data synchronization task. For example, the above-described synchronization type may be a "full-scale synchronization type". As another example, the above-described synchronization type may also be an "incremental synchronization type". The "full sync type" may be a sync type that synchronizes all data in the database. The "incremental sync type" may be a sync type in which generated data is synchronized after the time point is updated. The update time point may be a time point at the previous data synchronization. Therefore, the execution state of the data synchronization task can be monitored, and the multiple data synchronization tasks can be uniformly scheduled through the execution state.
In some embodiments, the execution subject may select, in response to the representation of the execution completion by the execution state information included in the value of the pre-parent task key value pair of the task key value pair, an execution node from the execution node cluster as a target execution node according to the health of each execution node in the execution node cluster. The pre-father task key value pair may be a task key value pair of a father data synchronization task of the target data synchronization task. And executing the data synchronization task corresponding to the prepositive parent task key value pair before the target data synchronization task. The execution nodes in the execution node cluster may be nodes for executing data synchronization tasks. The execution nodes in the execution node cluster may be databases. For example, the execution node may be a MYSQL database. The health degree can be used for quantifying the operation state of the equipment corresponding to the execution node. The larger the above-mentioned health degree is, the smaller the load characterizing the device corresponding to the execution node is. In practice, the health degree may be generated by the disk occupancy rate, the memory occupancy rate, the central processing unit occupancy rate, and the number of data synchronization tasks of the device corresponding to the corresponding execution node. For example, the executing entity may generate the health degree of each executing node in the executing node cluster by the following formula:
wherein, the health score represents the health of the execution node. A represents the disk occupancy of the device corresponding to the execution node. And B represents the memory occupancy rate of the device corresponding to the execution node. C represents the central processor occupancy of the device corresponding to the execution node. And D represents the number of data synchronization tasks executed on the equipment corresponding to the execution node.
The target execution node may be configured to, in response to that the connection status of the source database is a connected status, send, based on the target database address information, a data synchronization operation statement generated according to the source database address information and the synchronization type to the target database. The connection status may characterize a status type of the connection of the target execution node to the source database. For example, the connection status may be "connected status", and a user name and a user password characterizing that the network connection is normal or the source database is correct. For another example, the connection status may also be "unconnected status", which indicates that the network is unconnected, or that the user name and/or user password of the source database are incorrect. The data synchronization operation statement may be a programming statement for accessing data and querying and updating a database. For example, the data synchronization operation statement may be an SQL (Structured Query Language) statement.
In practice, the target execution node may generate the data synchronization operation statement by:
first, according to the synchronization type and the source database address information, obtaining data to be synchronized from the source database. In practice, the target execution node may, in response to that the synchronization type is a "full synchronization type," obtain full data in a table to be updated in the source database as data to be synchronized. The target execution node may further acquire, in response to that the synchronization type is an "incremental synchronization type," incremental data in the source database as data to be synchronized. The above-mentioned total data may be all data in the table to be updated. The incremental data may be data after the last export in the table to be updated.
And secondly, generating a data synchronization operation statement according to the data to be synchronized. In practice, the target execution node may generate a data synchronization operation statement based on the data to be synchronized and the target data synchronization operation command. The target data synchronization operation command may be a command (e.g., SQL command) in a structured query language. When the data to be synchronized is full data, the target data synchronization operation command is an "insert" command. And when the data to be synchronized is incremental data and the event type of data synchronization is updating, the target data synchronization operation command is an update command. The target database may be configured to execute the data synchronization operation statement to perform a data synchronization operation on the target database.
In practice, the execution subject may select an execution node satisfying a predetermined condition from the execution node cluster as a target execution node. The predetermined condition may be that "the health degree corresponding to the execution node is a maximum value of each health degree corresponding to each execution node in the execution node cluster".
Through step 302, a load-balanced execution node may be selected among the plurality of execution nodes, so that the load-balanced execution node may be determined as an execution node that executes the target data synchronization task.
Optionally, before step 302, first, the executing entity may obtain target data from the source database in response to the connection status of the source database being a connected status. The connection status may be a status type of connection between the execution subject and the source database. The target data may be at least one piece of data to be synchronized in the source database. And then, sending the preset data synchronization operation statement to the target database. The preset data synchronization operation statement may be a preset data synchronization operation statement. For example, the preset data sync operation statement may be "select 1". Finally, in response to receiving the execution result sent by the target database, a data delay detection result may be generated by various methods based on the time when the execution result is received and the time when the target data is acquired. The data delay detection result can represent whether data synchronization is delayed or not. The execution result may be a feedback result generated after the target database executes a preset data synchronization operation statement. The execution result may be an execution success or an execution failure. Therefore, the delay condition of the data synchronization can be detected before the data synchronization, and the frequency of abnormal conditions with long delay in the execution of the data synchronization task is reduced.
Optionally, the executing entity may generate the data delay detection result by:
step one, determining the time for acquiring the target data as target time. In practice, the execution subject may obtain the time for acquiring the target data by the following codes: an import time; time ().
And secondly, determining the interval duration between the time of receiving the execution result and the target time as a target duration. In practice, the execution subject may obtain the time when the execution result is received from a database for storing the time when the execution result is received. The execution subject may subtract the time of receiving the execution result from the target time to generate the target duration.
And thirdly, responding to the target duration meeting the preset condition, and generating a data delay detection result representing the data synchronization without delay. The preset condition may be that the target time length is less than a preset time length. Here, the setting of the preset time period is not limited.
In some optional implementations of some embodiments, the execution subject may select an execution node from the execution node cluster as a target execution node in response to the data delay detection result indicating that data synchronization is not delayed. Therefore, the target execution node can be selected to execute the data synchronization task under the condition that the data delay detection is passed, so that the frequency of abnormal conditions with long delay in the execution of the data synchronization task is reduced.
Optionally, the executing body may control the associated first alarm device to execute the first alarm operation in response to the data delay detection result representing the data synchronization delay. The first alarm device may be a display device. The first alarm operation may be an operation of displaying a predetermined icon. The predetermined icon may be a "warning icon". In practice, the execution body may control the associated display device to display a preset icon in response to the data delay detection result representing the data synchronization delay. Therefore, alarm prompt can be performed under the condition of data synchronization delay.
Optionally, first, the execution main body may obtain a data volume and a data obtaining speed of each execution node in the execution node cluster, where the data volume and the data obtaining speed are obtained from a corresponding source-end database, so as to obtain a data volume set and a speed set. Then, in response to the presence of a data amount satisfying the abnormal data amount condition in the set of data amounts or the presence of a speed satisfying the abnormal speed condition in the set of speeds, the associated second alarm device may be controlled to perform the second alarm operation. The abnormal data amount condition may be that the data amount is greater than a preset data amount. The abnormal speed condition may be "speed less than a preset speed". Here, the setting of the preset data amount and the preset speed is not limited. The second alarm device may be a sound box. The second alarm operation may be an operation of playing a preset audio. It is understood that the first alarm device and the second alarm device may be the same device or different devices. The first warning operation and the second warning operation may be the same operation or different operations. In practice, the execution subject may control the associated speaker device to play the preset audio. Therefore, the alarm prompt can be performed under the condition of abnormal data quantity or abnormal speed.
The above embodiments of the present disclosure have the following advantages: by the data synchronization method of some embodiments of the present disclosure, the number of data synchronization task interrupts is reduced. Specifically, the reason why the number of data synchronization task interruptions increases is that: when a plurality of data synchronization tasks exist, the number of times of load abnormality of the device executing the data synchronization tasks is increased. Based on this, the data synchronization method of some embodiments of the present disclosure first generates a task key value pair of the target data synchronization task in response to receiving parameter information of the target data synchronization task. The parameter information includes source database address information of a source database corresponding to the target data synchronization task, target database address information and synchronization type of a target database corresponding to the target data synchronization task. Therefore, the execution state of the data synchronization task can be monitored. Thus, a plurality of data synchronization tasks can be uniformly scheduled through the execution state. And then, responding to the representation of the execution state information included by the value of the prepositive parent task key value pair of the task key value pair, and selecting an execution node from the execution node cluster as a target execution node according to the health degree of each execution node in the execution node cluster. The target execution node is configured to send, in response to that the connection status of the source database is a connected status, a data synchronization operation statement generated according to the source database address information and the synchronization type to the target database based on the target database address information. The target database is used for executing the data synchronization operation statement. Thus, the execution node for load balancing can be selected from the plurality of execution nodes, and the execution node for load balancing can be determined as the execution node for executing the target data synchronization task. And the data synchronization tasks can be uniformly scheduled, and the load of the execution nodes executing the target data synchronization task is balanced, so that the frequency of load abnormality of equipment executing the data synchronization task can be reduced when a plurality of data synchronization tasks exist.
With further reference to fig. 4, a flow 400 of further embodiments of a data synchronization method is shown. The process 400 of the data synchronization method includes the following steps:
And 402, responding to the representation and the execution completion of the execution state information included in the value of the pre-father task key value pair of the task key value pair, and selecting an execution node from the execution node cluster as a target execution node according to the health degree of each execution node in the execution node cluster.
In some embodiments, the specific implementation and technical effects of steps 401-402 can refer to steps 301-302 in those embodiments corresponding to fig. 3, which are not described herein again.
And step 403, acquiring a target data synchronization operation log from the target database.
In some embodiments, an executing entity (e.g., the computing device 101 shown in fig. 1) of the data synchronization method may obtain the target data synchronization operation log from the target database through a wired connection or a wireless connection. The target data synchronization operation log may be a binary log file generated by the target database in real time and operating on the database data. For example, the target data synchronization operation log may be a Mysql Binlog log. The target data synchronization oplog may include a set of synchronization data. The synchronization data in the synchronization data set may be data that has been synchronized in the target data.
In some embodiments, for each synchronization data in the set of synchronization data, the execution subject may perform the following steps: determining whether the source database meets a preset abnormal condition corresponding to a data synchronization operation type corresponding to the synchronization data; and responding to the determination, and sending the synchronous data to the target terminal equipment. The data synchronization operation type may be a type of a data synchronization operation statement executed on the synchronization data. For example, the data synchronization operation type may be an "insert class". As another example, the data synchronization operation type described above may be a "delete class". When the data synchronization operation type is "insert type", the predetermined exception condition may be "the synchronization data exists in the source database". When the data synchronization operation type may be a "delete type", the predetermined exception condition may be "the synchronization data does not exist in the source database". The target terminal device may be a data synchronization monitoring terminal device communicatively connected to the execution main body. The target terminal device may also be a terminal device of a user who sends the parameter information. In practice, the execution body may transmit the synchronization data to the target terminal device by means of a wired connection or a wireless connection in response to the determination. Therefore, the synchronous data can be checked in real time, and the abnormal synchronous data can be positioned quickly.
The related content of step 403 plus 404 serves as an invention point of the embodiment of the present disclosure, and solves the technical problem mentioned in the background art that "the synchronous data often cannot be verified in real time, so that the abnormal synchronous data cannot be located quickly when the data synchronization is abnormal". When data synchronization is abnormal, the factors of not being able to locate abnormal synchronization data quickly are as follows: often, the synchronous data cannot be checked in real time. If the factors are solved, the effect of quickly positioning abnormal synchronous data when the data synchronization is abnormal can be achieved. To achieve this effect, the present disclosure obtains a target data synchronization operation log from the above-described target database. Then, for each synchronization data in the above synchronization data set, the following steps are performed: determining whether the source database meets a preset abnormal condition corresponding to a data synchronization operation type corresponding to the synchronization data; and responding to the determination, and sending the synchronous data to the target terminal equipment. Since the target data synchronization operation log records real-time synchronization data, the synchronized data can be verified in real time. Therefore, when the data synchronization is abnormal, abnormal synchronous data can be positioned quickly.
As can be seen from fig. 4, compared with the description of some embodiments corresponding to fig. 3, the flow 400 of the data synchronization method in some embodiments corresponding to fig. 4 embodies the steps extended by checking the synchronized data. Thus, the embodiments describe schemes that allow real-time verification of synchronized data. Therefore, when the data synchronization is abnormal, abnormal synchronous data can be positioned quickly.
