Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The embodiment of the invention provides a persistence method of memory state data for data languages, which aims at the current memory-based digital object warehouse mode of a digital Rayleigh operator, and referring to FIG. 1, a flow chart of the persistence method of memory state data for data languages for digital networking is shown, the persistence method is applied to a digital object warehouse node of a digital network of digital Rayleigh operator digital object warehouses, the digital object warehouse node of the digital network of digital Rayleigh operator digital object warehouses operates data language, and the data language is single-point data language, and the persistence method comprises the following steps:
Step 101: and in the running process of the single-point data language, according to the preset period in the preset storage mode, automatically storing the full state data of the single-point data language to the hard disk when each preset period expires.
In the embodiment of the invention, the single-point data language is characterized by self, typically arranged and run on a number of digital object warehouse number of a number of digital object warehouse nodes of the digital network, except the provider for the data language, other users who need to use the single-point data language need to apply certain rights to the provider for the data language, so that the single-point data language can be used. Different single-point data languages may be arranged on different ones of the digital object warehouse nodes, it is also possible to arrange the same number of number object warehouses.
Before the data language is used, namely before the single-point data language is started for the first time, the digital object warehouse node of the digital object warehouse of the digital object of the digital Rayleigh operator needs to receive configuration information and a preset storage mode; the configuration information can be configured by the data language booster in advance, and of course, the configuration information can also be configured by the user after applying for the authority, and the configuration information comprises: the stop save mode and the start load mode are described in detail below, and are not described in detail. The preset save mode is selected by the user before the data language is started.
The digital object warehouse node of the digital object warehouse of the digital Rayleigh operator receives a starting instruction, then starts the single-point data language through the single-point data language execution engine and various parameters for starting the single-point data language, the single-point data language can start to run, and the operation starts according to the configuration information and a preset storage mode.
In the single-point data word use operation process, assuming that a user does not have sporadic storage requirements, the number-end operator digital object warehouse node executes the single-point data word use based on the number-end operator digital object warehouse mode of the memory, and the full state data is stored in the memory, and the number-end operator digital object warehouse node automatically stores the full state data for the single-point data word use to a hard disk when each preset period expires according to the preset period in the preset storage mode. The preset period may be 12 hours, one day, two days, or the like.
As one example: taking 12 hours as an example, assume that the digital object warehouse node of the number of rayleigh operators at 9:00 starts single point data language usage and starts running, then at 21:00, the digital object warehouse node of the number Rayleigh operator automatically uses a single-point data word at 21: the full state data at 00 is saved to the hard disk, and during this time, the digital object repository node only stores the full state data in a single point data word in memory. Continuing to execute the single-point data language to 9 on the second day: at 00, the single-point data word is automatically used again at 21: and storing the full state data in 00 times to a hard disk, and the like until the single-point data language receives a stop request to stop running or the whole single-point data language normally runs.
Thus, even if the digital object warehouse node of the digital Rayleigh operator is in downtime, power failure and the like, the full state data in the memory is lost, but the data in the hard disk is not lost. And the data language execution time requirement and the data language execution throughput rate are not affected due to the periodical storage. Of course, it will be appreciated that if the number of rake digital object warehouse nodes occur within a certain period, for example: at 12: at time 00, the digital object warehouse node of the digital Rayleigh operator is down, so that the full state data for the single-point data word is not saved to the hard disk because the time of the preset period is not reached, and based on the problem, a solution is proposed in step 103, and is not repeated.
Of course, the user may set the preset period to be shorter, for example, 1 hour, and the digital object warehouse node of the digital Rayleigh operator will save the full-scale state data to the hard disk every hour according to the period of 1 hour. However, the shortening of the preset period increases the execution time of the digital object warehouse node of the digital Rayleigh operator for the single-point data language and the throughput of the single-point data language, so that the user can reasonably set the preset period according to the performance and other factors of the digital object warehouse node of the digital Rayleigh operator.
In addition, the preset storage mode further includes: the non-save mode is a mode of saving the full amount of state data for a single-point data word to the hard disk, and may be selected according to the actual needs of the user, for example, some single-point data words have a short life cycle or the user wants to save the state for the data word by manually sending a command, or the data word is a stateless data word and the full amount of state data does not need to be saved, and the save mode may be set to be non-save.
Therefore, in the running process of the single-point data word, if the preset storage mode is not the storage mode, the digital object warehouse node of the number-rate operator does not automatically store the full-state data for the single-point data word to the hard disk, and only stores the full-state data in the memory until a storage instruction is received or the situation that the single-point data word stops running occurs.
Step 102: at any moment in the single-point data language operation process, a storage instruction is received, and the full state data at the current moment is stored in the hard disk.
In the embodiment of the invention, for some single-point data words, some key nodes exist in the operation process, or when a user needs to store the full-quantity state data for the single-point data words at a certain moment, the user can store the full-quantity state data by means of a management tool for the single-point data words and the like by sporadically actively letting the digital object warehouse nodes of the digital Rayleigh operator. That is, at any time in the single-point data word operation process, a save instruction is received, and the digital object warehouse node saves the full-scale state data at the current time to the hard disk. The storage method can store the full-quantity state data for the single-point data language in the hard disk according to actual requirements, can ensure that the full-quantity state data for the single-point data language is not lost, and is convenient for later recovery of the full-quantity state data for the single-point data language. And due to sporadic storage, the execution time requirement of the data language and the execution throughput rate of the data language are not affected.
Along with the above example, assume that after one hour of operation, the single point data word is 10:00, the user needs to save the full-quantity state data for the single-point data language, then a save instruction is sent, and after the data Rayleigh operator digital object warehouse node receives the save instruction, 10: the full-quantity state data for the single-point data word at the time 00 is stored in the hard disk. After that the user has no sporadic save needs, then at 21:00, the digital object warehouse node of the number Rate operator stores 21 according to a preset period of 12 hours in a preset storage mode: full state data for single-point data words at time 00 is sent to the hard disk.
Step 103: when the single-point data language stops running at any moment in the running process of the single-point data language, the full state data of the single-point data language at the running stopping moment is automatically stored to the hard disk according to the stopping storage mode in the configuration information.
In the embodiment of the present invention, in order to prevent a situation that a single-point data word is used in a situation that a stop request is received to stop running in the running process but the whole amount of state data is lost, the configuration information includes: a stop save mode and a start load mode. The stop save mode means: when the operation is stopped at any moment in the single-point data language operation process, the full state data at the current moment is automatically stored to the hard disk. The boot loading method is as follows: after the single-point data language is restarted, the full-quantity state data at the stopping moment is automatically loaded and used as the initial full-quantity state data at the current running time of the single-point data language. The storage method ensures that the latest full-quantity state data for the single-point data word is not lost, and when the full-quantity state data for the single-point data word is recovered in the later period, the latest full-quantity state data before the operation is stopped is directly recovered, the state which is already operated is not required to be repeated, and the execution time requirement for the single-point data word and the execution throughput rate for the data word are also improved.
Along with the above example, assume that after ten hours of 10 minutes of operation for a single point data word, 19:10, the user wishes to stop the single point data word, then the digital rake digital object repository node will 19: and storing the full-quantity state data for the single-point data language at the moment 10 into a hard disk. After that, when the single-point data language is restarted, the digital object warehouse node of the digital Rayleigh operator automatically changes 19: the full-quantity state data at the time 10 is used as the initial full-quantity state data when the single-point data word is used for running at the current time.
It should be noted that, assuming that the single-point data word is started for the first time, it naturally does not have the full state data of the previous stop time of the single-point data word, so that only when the single-point data word receives a stop request to stop running and is restarted, the full state data of the single-point data word at the previous stop time is loaded according to the start loading mode in the configuration information; and then, using the full-quantity state data of the single-point data word at the previous running stopping time as the initial full-quantity state data of the single-point data word at the current running time, and continuing to run the single-point data word.
In the operation of storing the full-volume state data to the hard disk, the storing mode and the name of the single-point data word are used as the identification to be classified and stored generally at the moment of storing the full-volume state data, so that the user can find conveniently in the later recovery process, and the efficiency of the user is improved.
Step 104: after the operation of the single-point data language is finished, the operation result of the single-point data language is sent to a digital object warehouse node of the digital network for verification.
In the embodiment of the invention, if the single-point data language is used normally, an operation result is generated, and the operation result is only required to be used as the certification storage data to be sent to the digital object warehouse node of the digital network for storing certification in the digital object warehouse. Of course, the digital object warehouse node of the number Rayleigh operator can also store the running result, and the running result can be determined according to the requirement of a user.
Of course, the user can also make the digital object warehouse node of the digital sub-database take the full state data of a certain moment as the evidence storage data to generate to the digital object warehouse node of the digital sub-database, and then store the evidence in the digital object warehouse of the digital sub-database, however, the operation needs to occupy more operation resources of the digital object warehouse node of the digital operator, so that the requirement of the execution time for single-point data language is increased, and the execution throughput rate of the data language is reduced, and therefore, the operation can be implemented under the condition that the performance of the digital object warehouse node of the digital operator is very strong and the operation resources are relatively abundant.
In the embodiment of the invention, in the running process of the single-point data word, the full state data of the single-point data word can be stored according to the preset period, or the full state data of the single-point data word can be stored at any time according to the storage instruction, so that a user can restore the single-point data word to the single-point data word at the selected moment according to the self requirement. That is, at any time in the running process of the single-point data language, a recovery instruction is received, and full-quantity state data corresponding to the specified time in the recovery instruction is obtained from the hard disk; and then, according to the full state data corresponding to the designated time in the recovery instruction, the single-point data word is recovered to the full state at the designated time.
Similarly, when the single-point data word is restarted, loading the full state data of the single-point data word at the previous stopping operation time according to a starting loading mode in the configuration information; and taking the full-quantity state data of the single-point data word used at the previous running stopping time as the initial full-quantity state data of the single-point data word used at the current running time, and continuing to run the single-point data word. In addition, if the single-point data word is stopped and restarted after receiving the stop request, the preset period starts to be counted according to the restart time as the starting time, and the preset period is automatically saved until the preset period is not calculated by the time when the single-point data word is started for the first time.
Along with the above examples: suppose single point data word 9:00 starts to run for the first time, and after one hour of running, namely 10:00, the user needs to save the full-quantity state data for the single-point data language, then a save instruction is sent, and after the data Rayleigh operator digital object warehouse node receives the save instruction, 10: the full state data for the single-point data word at the time 00 is stored in the hard disk, and the full state data stored in the hard disk is stored at the time point: 10:00, save type: sporadically, the names are used together as identifiers in combination with the single-point data words for users to find. After that, the user has no sporadic storage requirement, and the single-point data language continues to run for ten hours and 10 minutes, namely 19:10, the single point data word is stopped by receiving a stop request, then the digital object repository node will 19: the full state data for the single-point data word at the time 10 is stored in the hard disk, and the full state data stored in the hard disk at the time point: 19:10, preservation type: stopping storing, and using the name together as the identification by combining the single-point data language for searching by the user. The user is at 20:06 need to restart the single-point data word, two identifications can be found at this time, one is 10: sporadic saving at time 00, one is 19: and stopping saving at the time 10, and enabling a user to select any time to recover the single-point data language.
Suppose that the user selects 10: the sporadically saved full-volume state data at time 00 is shown at 20:08 restart the single-point data word, then the single-point data word is used to 10: the full-quantity state data at the moment 00 is the initial full-quantity state data at the current running time, and the single-point data language is continuously run. After the single-point data language is started and operated, the method uses 20:08 as the new start time of the preset period. At 8:08, the digital object warehouse node of the number Rayleigh operator stores 8 according to a preset period of 12 hours in a preset storage mode: full state data for single-point data words at time 08 is stored in the hard disk at the time point: 8:08, save type: the periodicity is preset, and the name is used as a mark together in combination with the single-point data language so as to be searched by a user.
In summary, through the three storage methods, the persistent storage of the full-quantity state data for the single-point data in the operation life cycle of the single-point data is ensured, the full-quantity state data cannot be lost due to the problems of downtime, power failure and the like of the warehouse node of the Rayleigh operator digital object, and the single-point data for the latest full-quantity state data or the single-point data for the full-quantity state data at the selected moment or the key node can be restored in the later recovery.

In order to verify the reliability of the persistence method of the invention, experimental tests and evaluations were performed on the persistence method for data languages.
The digital data networking system is a typical digital data networking system based on memory operation data language. The system comprises 1 device, 7 devices and a plurality of digital object warehouse nodes, wherein the 1 device is used as a digital data networking identification analysis system, the 1 device is used as a digital data storage digital object warehouse node, and the 7 devices are used as digital data sub-digital object warehouse nodes. The application is exemplified as a single-point data language application with a simple key value, which is a data language application for creating users and transferring operations between users, and experiments can be performed using any currently known single-point data language application.
And configuring the application items by using the simple key values to obtain configuration information, so that the data words can automatically store the full state data to the hard disk before stopping and can automatically recover when restarting. After writing the simple key-value pair application program code, the data language is started, some user creation and transfer operations are performed, all users and account balances thereof are queried, and as shown in fig. 3, all user account balances before the simple key-value pair application (the simple key-value pair application is represented by kv in fig. 3, 4 and 5) is stopped are shown. "viewAll" in FIG. 3 refers to a simple key value that implements the viewAll method for querying the user account balance for an application; success (2 ms) identifies the Success of the execution result and takes 2 ms; person1, person2, person4, person3, person5 refer to five user accounts, respectively, with the corresponding balances: 990. 1055, 425, 955, 1575. The simple key value is then forced to stop the application.
After the application is forcibly stopped by the simple key value, each digital object warehouse node of the number Rayleigh operator can automatically store the simple key value before stopping to the hard disk for the application full state data. And then restarting the simple key value pair application, and not executing any data language call and other operations, wherein the simple key value pair application automatically restores to a state before forced stopping, and in order to verify the conclusion, executing a simple key value pair application view all method again to obtain the information of the balance of each user and account in the current simple key value pair application, and arranging the results as the following table:
comparison with fig. 3 concludes: the simple key value has automatically completed state recovery for the application.
In another case, configuration information in a simple key-value pair application is first deleted, after which 5 user accounts are created in the simple key-value pair application: person1, person2, person3, person4, person5, and the remainder set to 1000, the query balance is shown in fig. 4.
At this time, a save instruction is sent through a simple key value corresponding application instance management tool, so that the digital object warehouse node of the digital Rayleigh operator saves the full-quantity state data of the simple key value pair application at the current moment, and a state file '2021-02-22.14' is generated: 22:55", i.e. 22 nd of 2020, 14 th and 22 min 55 s, holds the full state data of the simple key value pair application to the hard disk. And restarting the application after stopping the simple key value, wherein the configuration information is deleted, so that the digital object warehouse node of the digital Rayleigh operator cannot automatically save the full-quantity state data of the application at the stopping moment of the simple key value, and cannot automatically recover the full-quantity state data at the stopping moment after restarting. When the simple key-value application is restarted, the user account balance in the simple key-value application is first queried as shown in FIG. 5.
In fig. 5, since the simple key value pair full-quantity state data of the application is not saved to the hard disk, and the characteristic of the memory number identifier digital object warehouse mode causes the simple key value pair full-quantity state data to be lost in the late stage of application stop, no user account exists in the complete execution result, and naturally no balance of the user account exists.
Finally, work selection status file "2021-02-22.14 is managed by the data language instance: 22:55", sending a recovery instruction, and then carrying out all account balance inquiry again, wherein the inquiry result is shown in the following table:
comparison with fig. 4 and 5 concludes: the simple key value indicates that the application has completed its recovery of the full amount of state data by the recovery instruction.
