Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person skilled in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
It will be appreciated that prior to using the technical solutions disclosed in the embodiments of the present disclosure, the user should be informed and authorized of the type, usage range, usage scenario, etc. of the personal information related to the present disclosure in an appropriate manner according to the relevant legal regulations.

It will be appreciated that the data (including but not limited to the data itself, the acquisition or use of the data) involved in the present technical solution should comply with the corresponding legal regulations and the requirements of the relevant regulations.
In the use process of the product, the situation that the login state of the object is switched is often involved. For example, when a subject starts daily use of a product, the subject uses the product in a non-login state and registers login use after a certain period of time. Or when the equipment is replaced, the object does not log in the product to be used on the new equipment at first, and log in the product to be used is used after a period of time.
When the product is used in the non-login state, the product usage analysis system can consider some actions in the non-login state as new objects to be executed, so that event data of the same object in the non-login state and in the login state are divided into event data of different objects to be stored, and inaccurate identification of the event data is caused.
In view of the above, in accordance with the disclosed embodiments, there is provided a data repair method embodiment, it is noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system, such as a set of computer executable instructions, and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order other than that illustrated herein.
In this embodiment, a data repairing method is provided, which may be used in a product usage analysis system, and fig. 1 is a schematic flow chart of a data repairing method according to an embodiment of the disclosure, as shown in fig. 1, where the flow chart includes the following steps:
in step S101, if the login change message is acquired, the first data identifier in the non-login state and the second data identifier in the login state in the login change message are acquired, and the login change message is used for indicating that the login state is switched from the non-login state to the login state.
Specifically, as shown in fig. 2, when an object logs in on the device, a login request is triggered to the identifier service system, and when the identifier service system determines that the login involves switching from the non-login state to the login state, a login change message is generated based on the first data identifier in the non-login state and the second data identifier in the login state.
Step S102, determining a first storage area and first event data based on the first data identification.
Specifically, an event database for storing event data may be constructed in advance, and a plurality of slices are provided in the event database. In each fragment, corresponding event data is stored according to the data identification, each fragment can store event data of a plurality of data identifications, and event data corresponding to the same data identification is stored in the same storage area.
In actual operation, based on the first data identification, a corresponding first storage area in the pre-constructed event data is determined, and the first event data in a non-login state is acquired from the first storage area.
In particular, the event database may be built by the columnar database management system ClickHouse. Or constructing the event database through a relational database management system MySQL, and the construction mode of the event database is not limited.
In addition, other data storage modes may be used to store event data corresponding to different data identifiers, such as file systems, block storage, object storage, etc., and the storage modes of the event data are not limited herein.
Step S103, determining a second storage area and second event data based on the second data identification.
Specifically, based on the second data identifier, a corresponding second storage area in the pre-constructed event data is determined, and the second event data in the login state is acquired from the second storage area.
Step S104, the first event data is moved from the first storage area to the second event data in the second storage area, so as to update the second event data.
For example, in actual use of a product, event data for the same object is typically stored on the same tile for ease of data analysis and data management. However, when the product analysis system stores data, the data in the non-login state is often regarded as a new object to be executed, so that a new data identifier is allocated to store event data in the non-login state. As shown in fig. 2, it is assumed that event data in the non-login state is stored in the patch 1, and event data in the login state is stored in the patch 2. At this time, since event data of the same object is stored in each of the slices 1 and 2, it is necessary to move event data in a non-login state on the slice 1 to event data in a login state of the slice 2 so that event data of the same object is stored in a unified manner.
In the data restoration method provided in this embodiment, if a login change message for switching from a non-login state to a login state is obtained, a first data identifier in the non-login state and a second data identifier in the login state in the login change message are obtained. Then, a first storage area and first event data are determined based on the first data identification, and a second storage area and second event data are determined based on the second data identification. And moving the first event data from the first storage area to the second event data in the second storage area so as to update the second event data. Therefore, the event data of the same object in the non-login state and the login state can be uniformly stored, so that the event data of the same object can be repaired, and the accuracy of subsequent product analysis is improved.
In some optional embodiments, the data repair method of the present disclosure further includes, after the step S101, the steps of: transmitting the first data identifier and the corresponding second data identifier to a distributed publish-subscribe message system; creating an identification information table; based on the distributed publishing and subscribing message system, the first data identification and the corresponding second data identification are written into an identification information table.
For example, taking ClickHouse to manage event data as an example, if a login change message is obtained, a first data identifier in a non-login state and a second data identifier in a login state in the login change message are sent to a distributed publish-subscribe message system (english: kafka) to generate a message queue. Then, an identification information table is created at ClickHouse to consume the message content format of Kafka to write the first data identification and the second data identification into the identification information table. Therefore, in the subsequent data repairing process, the first data identifier in the non-login state and the second data identifier in the corresponding login state can be determined according to the identifier information table, so that the first event data in the non-login state is moved to the second event data in the corresponding login state, and the event data of the same object is repaired.
In addition, as shown in fig. 2, the identification information table may be correspondingly stored on the segment where the first storage area is located, so as to determine whether there is first event data in the non-login state that needs to be moved on the current segment.
According to the data restoration method provided by the embodiment, the first data identifier in the non-login state and the second data identifier in the corresponding login state are sent to the distributed publish-subscribe message system, and then the first data identifier and the corresponding second data identifier are written into the created identifier information table by utilizing the distributed publish-subscribe message system. Therefore, in the subsequent data restoration process, the first event data in the non-login state which needs to be restored can be quickly determined, so that the data restoration efficiency is improved.
In some optional embodiments, the acquiring the first event data in the non-login state in step S102 based on the first data identifier includes: when a preset repair starting condition is met, if a first data identifier is stored in the identifier information table, a first storage area and first event data are determined based on the first data identifier.
Specifically, the repair initiation condition is whenever a preset period is reached. The preset period may be 2 hours, 6 hours, 1 day or one week, and may be determined according to practical situations. In addition, the repair initiation condition may be when a repair instruction is received, or when a product analysis task is started. In actual operation, the repair starting conditions can be adjusted according to actual conditions.
It will be appreciated that during the use of the product, a large number of login change messages may be involved, and if one login change message is obtained, a large amount of computing resources are occupied if data repair is performed once, and frequent data movement easily causes data errors. Thus, the repair task may be performed at regular intervals, e.g., 1 am a day, once. Or perform a repair task every 2 hours.
According to the data restoration method provided by the embodiment, when the restoration starting condition is met and the first data identifier in the non-login state is stored in the identifier information table, the first storage area and the first event data in the non-login state are acquired based on the first data identifier. Therefore, frequent data repair can be avoided, and unnecessary computing resource occupation is reduced. Meanwhile, whether the first event data in the non-login state which needs to be moved or repaired exists or not can be rapidly determined according to the data condition in the identification information table.
In some optional embodiments, the step S104 of moving the first event data from the first storage area to the second event data in the second storage area to update the second event data includes:
Step a1, creating a temporary data table in the first storage area, wherein the temporary data table is used for storing first event data.
And a step a2 of moving the first event data from the first storage area to the second event data in the second storage area based on the temporary data table so as to update the second event data.
It should be noted that, considering that data loss or data corruption may occur during the process of data migration or copying, if modification is directly performed on the original event data, data errors and even data crashes are easily caused. Therefore, the temporary data table needs to be used for backing up the first event data, and then the first event data in the temporary data table is moved to the second event data in the second storage area, so that when the data loss or the data damage occurs, the temporary data table can be used for data recovery.
In the data restoration method provided in this embodiment, when the first event data of the first storage area is moved to the second event data of the second storage area, the temporary data table is created first, the first event data of the first storage area is copied to the temporary data table to be cached, and then the data of the temporary data table is moved to the second event data of the second storage area. Therefore, even if the data movement fails, the temporary data table can be used for data recovery so as to ensure the reliability of the data movement process.
In some alternative embodiments, creating the temporary data table in the first storage area in the step a1 includes: creating an initial data table, wherein an identification field is arranged in the initial data table, and the identification field is a first data identification; and moving the first event data to the initial data table, and modifying the identification field into a second data identification to obtain a temporary data table.
Illustratively, using ClickHouse as an example, the data identifications can be used as column names, and then event data for different data identifications can be stored in a columnar storage manner. When the first event data corresponding to the first data identifier is copied to the initial data table, the identifier field of the initial data table is the first data identifier. Therefore, if the first event data in the initial data table is to be moved to the second event data corresponding to the second data identifier, the identifier field of the initial data table needs to be modified to the second data identifier, so that ClickHouse can move the first event data to the second event data corresponding to the second data identifier according to the second data identifier, so as to update the second event data.
According to the data restoration method provided by the embodiment, an initial data table with an identification field being the first data identification is created, then the first event data is moved to the initial data table, the identification field is modified to be the second data identification, and a temporary data table is obtained. Therefore, the first event data in the temporary data table can be moved to the second event data of the corresponding second data identifier according to the identification field in the temporary data table, and the reliability of data movement can be further improved.
In some optional embodiments, the step a2 of moving the first event data from the first storage area to the second event data in the second storage area based on the temporary data table to update the second event data includes: if the first storage area and the second storage area are located in the same partition, the first event data in the temporary data table is moved to the second event data in the second storage area, and the first event data in the first storage area is deleted.
In the data restoration method provided in this embodiment, when the first storage area and the second storage area are located in the same partition, the temporary data table is used as an intermediate transmission medium to move the first event data from the first storage area to the second event data in the second storage area. Therefore, the original event data can be prevented from being directly modified, so that when the data movement fails, the temporary data table is utilized to repair the data, and the reliability of the data movement is ensured. And deleting the first event data in the first storage area, releasing the storage space and reducing the space occupation of redundant data.
In some optional embodiments, the step a2 of moving the first event data from the first storage area to the second event data in the second storage area based on the temporary data table to update the second event data further includes: if the first storage area and the second storage area are located in different fragments, creating a target data table in the second storage area; moving first event data in the temporary data table to the target data table; and moving the first event data in the target data table to the second event data in the second storage area, and deleting the first event data in the first storage area.
For example, as shown in fig. 2, in performing a repair task, it is assumed that a first storage area is located in a partition 1 and a second storage area is located in a partition 2, and since the partitions are located on different machines, it is impossible to directly locally move first event data of the first storage area to second event data stored in the second storage area. Therefore, the data of the temporary data table of the segment 1 can be transmitted to the target data table of the segment 2 through network transmission, and then the first event data in the target data table is moved to the second event data in the second storage area.
According to the data restoration method provided by the embodiment, when the first storage area and the second storage area are located in different fragments, first event data of the temporary data table is transmitted to the target data table of the second storage area, then the first event data in the target data table is moved to second event data of the second storage area, so that when the data movement fails, the data movement can be carried out again based on the target data table, and the reliability of the data movement is ensured. And deleting the first event data in the first storage area, releasing the storage space and reducing the space occupation of redundant data.
By way of example, the data repair method of the present disclosure is illustrated in a specific embodiment, as shown in fig. 3, which includes the steps of:
step S201, judging whether first event data corresponding to the first data identification in the non-login state exists in each storage area, if yes, executing step S202, and if not, ending the repair task.
Step S202, first event data is read from a first storage area corresponding to the first data identifier, and the first event data is stored in a pre-created initial data table, wherein an identifier field in the initial data table is the first data identifier.
Step S203, the identification field in the initial data table is modified from the first data identification to the second data identification in the login state, and a temporary data table is obtained.
Step S204, deleting the first event data identified by the first data in the first storage area.
Step S205, the first event data in the temporary data table is moved to the second event data in the second storage area corresponding to the second data identifier.
It should be noted that, in the data repairing method of the present disclosure, the temporary data table is obtained by moving the event data in the non-login state to the pre-created initial data table. Then, the event data in the non-login state of the original storage area is deleted. And moving the event data in the temporary data table to the event data in the corresponding logging state. Therefore, event data of the same object can be repaired. Meanwhile, the temporary data table is used for caching event data in a non-login state, and then the event data in the non-login state is moved to the event data in the corresponding login state, so that on one hand, when the data movement fails, the event data in the temporary data table can be used for repairing again, on the other hand, the original data storage area can be prevented from being operated for multiple times, and data errors are avoided to a certain extent.
