Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

It should be noted that, in order to reduce the pressure on the database, a cache technique is required to improve the performance. The processing performance and stability of the database are improved by using the caching technology, but the problem of data consistency is also brought.

The data consistency problem refers to that when multiple users attempt to access a database at the same time and their transactions use the same data at the same time, the following four situations may occur: missing updates, undetermined dependencies, inconsistent analysis, and phantom reads.

In order to solve the problem of data consistency, the present application discloses a data caching method, which distinguishes data types of required data and processes cached data in a cache region according to the data types of the required data, and the data caching method according to the embodiment of the present application is described below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a data caching method according to an embodiment of the present application, and as shown in fig. 1, the data caching method includes the following steps:

step 101, responding to an operation instruction of a user to a service system, and determining required data corresponding to the operation instruction.

It should be noted that, in the embodiment of the present application, the required data may be acquired from a data database or a cache region; and when the cache data corresponding to the required data does not exist in the cache region, acquiring the required data from the database. And when the cache data corresponding to the required data exists in the cache region, acquiring the required data from the cache region.

As an example, when the user a wishes to check the voting data of a certain game, and in response to an operation instruction of the user a to the service system, it is determined whether the cache data corresponding to the required data exists in the cache area, and if the data in the cache area is empty at this time, the number of votes is read from the database as 5.

As an example, when a user a wishes to check voting data of a certain match, and in response to an operation instruction of the user a to the service system, whether cache data corresponding to required data exists in the cache region is determined, and at this time, cache data corresponding to the required data exists in the cache region, the number of votes is read from the cache region to be 5.

At step 102, the data type of the desired data is determined.

It should be noted that the data type of the required data may include, but is not limited to, one or more of number type, string type, map type, and the like.

Alternatively, the number type of required data may be mathematically operated, for example, the required data is: and 5, adding 1 ticket to the required data, and changing the obtained required data into: and 6, the number of the tickets, wherein the required data is number type data.

string type modification can be performed on string type required data, for example, the required data is: monday is a sunny day, the required data can be modified, the sunny day is modified into a cloudy day, and the required data is obtained: monday is a cloudy day, where the required data is string type data.

The map type required data can be modified according to a key-value (according to a keyword value), for example, the required data is the content of an article, the basic information of the article is a key-value structure, and the key-value structure of the article can be modified. Wherein the required data is of the map type.

Step 103, processing the cache data in the cache region according to the required data and the data type thereof, and updating the validity period of the cache data processed in the cache region.

It should be noted that, in the embodiment of the present application, the processing includes creating cache data, modifying cache data, and deleting cache data, where creating cache data refers to creating non-existing cache data in a cache area, and the triggering condition of creating cache data includes: (1) after the required data are read from the database, newly building cache data corresponding to the required data in a cache area; (2) when the required data is written into the database and cached in the cache region, it should be noted that the triggering can be performed when one of the triggering condition (1) and the triggering condition (2) is satisfied.

In the embodiment of the application, modifying the cache data refers to modifying existing cache data, the trigger condition for modifying the cache data is to modify required data in the database, and the modified cache data is used as newly-built cache data in the cache region.

In an embodiment of the present application, deleting cache data refers to deleting cache data already existing in a cache region, and the trigger condition for deleting cache data includes: (1) and automatically deleting the cache data existing in the cache region after the validity period is exceeded. (2) And when the required data in the database is deleted, automatically deleting the cache data corresponding to the required data in the cache region.

According to the data caching method, the data types of the required data are divided, so that the data in different types are cached and processed in different areas, the cache utilization rate can be improved, the purpose of automatic caching is achieved, the cache technology can be effectively utilized to improve the system performance, the database operation pressure is reduced, and the database operation stability is ensured. In addition, the cache data in the cache region is processed, the validity period is set for the cache data, the validity period can be updated after the cache data are processed every time, and if the cache data exceed the validity period, the cache data can be automatically deleted, so that the problem of data consistency is solved, and the processing performance of the system is further improved.

It should be noted that, when the operation instruction is a first operation instruction, the first operation instruction may be a read data operation instruction. If the cache data can not be obtained from the cache region, the required data can be obtained from the database. As shown in fig. 2, fig. 2 is a flowchart of another data caching method according to an embodiment of the present application, where the method includes the following steps:

step 201, responding to an operation instruction of a user to a service system, and determining required data corresponding to the operation instruction.

In the embodiment of the present application, step 201 may be implemented by using any one of the embodiments of the present application, which is not limited in this embodiment and is not described again.

At step 202, the data type of the desired data is determined.

In the embodiment of the present application, step 202 may be implemented by any one of the embodiments of the present application, which is not limited in this embodiment and is not described again.

Step 203, determine whether there is cache data corresponding to the required data in the cache region.

In the embodiment of the application, as an implementation manner, the cache data in the cache region is divided into data types in advance, the cache data is stored in the cache region in a divided manner, and when it is determined whether the cache data corresponding to the required data exists in the cache region, the cache data in the corresponding region can be searched according to the type of the required data.

As an example, according to an operation instruction of the user a, it is necessary to determine whether cache data corresponding to the required data B exists in the cache region, and first determine that the required data B is number-type data, and then search from a number-type cache data region in the cache region.

In the embodiment of the application, as an implementation manner, tagging is performed on cache data in a cache region in advance, when it is determined whether cache data corresponding to required data exists in the cache region, a keyword of the required data is extracted, the keyword of the required data is compared with a tag of the cache data according to the keyword of the required data, several similar cache data are selected, and then the several similar cache data are compared with the required data to determine which cache data corresponds to the required data.

As an example, according to an operation instruction of the user a, it is necessary to determine whether cache data corresponding to the required data B exists in the cache region, and tag processing is performed on the cache data in the cache region in advance, where the cache region includes three cache data, and tags of the three cache data are "× article content", "football game ticket number", and "basketball game ticket number", respectively, and it can be known that a keyword of the required data B is "ticket number" by extracting the keyword of the required data B. The cache data which are relatively similar in the cache area are cache data with the labels of football game ticket number and basketball game ticket number, and the required data and the cache data are further compared to obtain the cache data with the label of basketball game ticket number which is the cache data corresponding to the required data.

And step 204, in response to that the cache data corresponding to the required data does not exist in the cache region, acquiring the required data from the database.

For example, suppose the database is provided with a user data acquisition interface, the user requirement can be determined through the interface, and the corresponding required data is searched from the database according to the user requirement. It should be noted that the form of the user's request may be a voice form or a text form. When the user needs to be in a voice form, voice recognition can be performed on the voice input by the user, and the voice can be converted into corresponding text information.

In the embodiment of the application, in response to the cache data corresponding to the required data existing in the cache region, the cache data corresponding to the required data is directly read from the cache region, and the cache data is returned to the service system.

Step 205, caching the required data into the cache region according to the data type, and using the required data as newly-built cache data in the cache region.

As an example, when the user a wishes to view the voting data of a certain game, at this time, the cache data corresponding to the required data does not exist in the cache region, so that the number of votes extracted from the database is 5, the 'number of votes 5' is the required data, and the required data is number type data, and the required data is cached in the cache region as newly created cache data.

As another example, when the user a wishes to view the information of the article B, at this time, the cache data of the article B does not exist in the cache region, so the content of the article B is extracted from the database, "this is a test article content", and "this is a test article content", which is the required data, and the required data is map-type data, and the required data is cached in the cache region as newly-created cache data, it is determined that the article basic information is a key-value structure, so the cache uses map-type storage, and the key is article _ info _1, and the key-value is article id:1234, author (author): three, title: (title), test title, createtime (generation time): 2021-01-01.

And step 206, setting the validity period of the newly-built cache data in the cache region.

In order to improve performance and further enhance stability and robustness of the cache system, in some embodiments of the present application, it may be determined whether cache data exceeding a validity period exists in a cache region; and in response to the cache data exceeding the validity period existing in the cache region, deleting the cache data exceeding the validity period from the cache region.

As an example, at this time, three cache data exist in the cache region, wherein the validity period of the cache data a is five minutes, and the remaining time is three minutes; the validity period of the cache data B is six minutes, and the remaining time is two minutes; the validity period of the cache data C is five minutes, and the remaining time is zero; if the validity period of the cache data C in the cache region is determined to have exceeded, the cache data C is deleted from the cache region.

As an example, when the user a wishes to view the voting data of a certain game, at this time, the cache data corresponding to the required data does not exist in the cache region, so that the number of votes extracted from the database is 5, the 'number of votes is 5' is taken as the required data, and the required data is number type data, and the required data is cached in the cache region as newly created cache data. At this time, an effective period is set for the newly-built cache data, and the effective period is ten minutes.

As another example, when the user a wishes to view the information of the article B, at this time, the cache data of the article B does not exist in the cache region, so the content of the article B is extracted from the database, "this is a test article content", and "this is a test article content", which is the required data, and the required data is map-type data, and the required data is cached in the cache region as newly-created cache data, it is determined that the article basic information is a key-value structure, so the cache uses map-type storage, and the key is article _ info _1, and key-value is article id:1234, author (author): zhang, title: (title), test title, createtime (generation time): 2021-01-01, and validity period is 5 minutes.

It should be noted that, in the embodiment of the present application, when the cached data is within the validity period, the user may perform processing operation on the cached data according to the need of the user, and if the cached data exceeds the validity period, the user has no way to perform processing operation on the cached data, where the processing operation includes operations such as access and modification.

According to the data caching method, when cache data corresponding to the required data does not exist in the cache region, the required data is obtained from the database, the user can obtain the required data timely, the required data is used as newly-built cache data in the cache region, the newly-built cache data can be obtained when the cache region does not have the cache data, the problem of data consistency is solved in sequence, and support for obtaining the required data by subsequent users is provided.

It should be noted that, when the operation instruction is a second operation instruction, the second operation instruction is to write data into the database. When data writing operation is carried out on the database, the input result can be cached. As shown in fig. 3, fig. 3 is a flowchart of another data caching method according to an embodiment of the present application, where the method includes the following steps:

step 301, responding to an operation instruction of a user to a service system, determining required data corresponding to the operation instruction.

In the embodiment of the present application, step 301 may be implemented by using any one of the embodiments of the present application, which is not limited in this embodiment and is not described again.

Step 302, determining the data type of the required data.

In the embodiment of the present application, step 302 may be implemented by using any one of the embodiments of the present application, which is not limited in this embodiment and is not described again.

Step 303, write the required data into the database.

For example, it is assumed that the data caching method of the embodiment of the present application can provide a data input interface for a user, and a database can obtain required data input by the user through the interface. It should be noted that the form of the required data input by the user may be a voice form or a text form, and when the required data input by the user is a voice form, the required data in the voice form may be subjected to voice recognition first and converted into corresponding text information.

And step 304, caching the required data into the cache region according to the type of the required data, and enabling the required data to be used as newly-built cache data in the cache region.

As an example, after the user a writes data with the content of "ticket number 5" into the database, it is determined that the data with "ticket number 5" is number type data, and the data with "ticket number 5" is used as newly created cache data in the cache area.

As another example, after the user a writes data with content "this is a test article content. - > into the database, it is determined that the data is map type data, and the data" this is a test article content. - > is used as new cache data in the cache region, and when the new article basic information is cached, it is determined that the data basic information is a key-value structure, so the cache uses map type storage, key is angle _ info _1, key-value is angle id:1234, author: zhang, title: test article title, createtime: 2021-01-01.

And 305, setting the validity period of the newly-built cache data in the cache area.

As an example, after the user a writes data with the content of "ticket number 5" into the database, it is determined that the data with "ticket number 5" is number type data, and the data with "ticket number 5" is used as newly created cache data in the cache area. At this time, an effective period is set for the newly-built cache data, and the effective period is ten minutes.

As another example, after the user a writes data with content "this is a test article content. - > into the database, it is determined that the data is map type data, and the data" this is a test article content. - > is used as new cache data in the cache region, and when the new cache data is cached, it is determined that the data basic information is a key-value structure, so the cache uses map type storage, key is angle _ info _1, key-value is articlelld: 1234, author: zhang, title: test article title, createtime:2021-01-01, and the validity period is five minutes.

It should be noted that, when the cached data is within the validity period, the user may perform processing operation on the cached data according to the need of the user, and if the cached data exceeds the validity period, the user has no way to perform processing operation on the cached data, where the processing operation includes operations such as access and modification.

According to the data caching method, the required data written into the database are used as newly-built cache data in the cache region, updating operation of the cache data is achieved, the problem of data consistency is solved, the required data are cached according to the type of the required data, classified type management of the cache region is achieved, pressure of the database is reduced, and performance of the database is improved.

It should be noted that, when the operation instruction is a third operation instruction, the third operation instruction is to modify the required data in the database. When the required data in the database is modified, the modified result is also subjected to caching operation. As shown in fig. 4, fig. 4 is a flowchart of another data caching method provided in the embodiment of the present application, where the method includes the following steps:

step 401, in response to an operation instruction of a user to a service system, determining required data corresponding to the operation instruction.

In the embodiment of the present application, step 401 may be implemented by using any one of the embodiments of the present application, which is not limited in this embodiment and is not described again.

Step 402, determining the data type of the required data.

In the embodiment of the present application, step 402 may be implemented by using any one of the embodiments of the present application, which is not limited in this embodiment and is not described again.

At step 403, content modification is performed on the required data in the database.

And step 404, modifying the cache data corresponding to the required data in the cache region according to the data type of the required data.

It should be noted that, in some embodiments of the present application, if the data type of the cache data is a number type, the mathematical operation may be performed on the cache data of the number type of cache data, and the modification operation on the cache data is implemented according to the mathematical operation.

In some embodiments of the present application, if the data type of the cached data is string type, the string type modification operation may be performed on the string type cached data.

In some embodiments of the present application, if the data type of the cache data is a map type, the key of the cache data of the map type may be updated, so as to implement the modification operation on the cache data.

As an example, after the user a writes data with a content of "ticket number 5" into the database, another user B adds a vote after viewing the data, and determines that the data with the content of "ticket number 5" is number type data, so that the data with the content of "ticket number 5" is changed into data with a content of "ticket number 6", and the cache data corresponding to the data with the content of "ticket number 5" in the cache area is found and modified, and the content corresponding to the cache data is modified into "ticket number 6".

As another example, after the user a writes data with content "this is a test article content. - > into the database, another user B modifies the data with content" this is a test article content. - > after viewing the data, and may determine that the data type is a map type, and modify the cache data with content "this is a test article content. - > in the cache region" this is a test article content. - > according to the data type of the data with content "this is a test article content. -" this is a cache data corresponding to the data.

Step 405, updating the validity period of the modified cache data.

As an example, after the user a writes data with a content of "ticket number 5" into the database, another user B adds a vote after viewing the data, and determines that the data with the content of "ticket number 5" is number type data, so that the data with the content of "ticket number 5" is changed into data with a content of "ticket number 6", and the cache data corresponding to the data with the content of "ticket number 5" in the cache area is found and modified, and the content corresponding to the cache data is modified into "ticket number 6". The modified cache data is again saved in the cache area, and the validity period is updated to five minutes again.

As another example, after the user a writes data with content "this is a test article content. - > to the database, another user B modifies the data with content" this is a test article content. - > after viewing the data, and may determine that the data type is a map type, modify the cache data with content "this is a test article content. - > in the cache region" this is a test article content. - > according to the data type of the data with content "this is a test article content. -" and store the modified cache data in the cache region again, and update the validity period again to ten minutes.

According to the data caching method, the required data are modified according to the data type of the required data, the operation pressure of the database is reduced, the performance of the database is improved, the stability of the database is improved, the cache data corresponding to the required data in the cache area are modified correspondingly after the required data are modified, and the problem of data consistency is solved.

It should be noted that, when the operation instruction is a fourth operation instruction, the fourth operation instruction is to delete the required data in the database, and delete the cache data corresponding to the required data. As shown in fig. 5, fig. 5 is a flowchart of another data caching method according to an embodiment of the present application, where the method includes the following steps:

step 501, responding to an operation instruction of a user to a service system, and determining required data corresponding to the operation instruction.

In the embodiments of the present application, step 501 may be implemented by any one of the embodiments of the present application, which is not limited in this embodiment and is not described in detail herein

Step 502, determining the data type of the required data.

In the embodiment of the present application, step 502 may be implemented by any one of the embodiments of the present application, which is not limited in this embodiment and is not described again.

Step 503, delete the data needed in the database corresponding to the business system.

And step 504, according to the deleted required data, deleting the cache data corresponding to the deleted required data in the cache region.

As an example, when the user a performs a deletion operation on the data of "the number of votes is 5" in the database, it is determined that the data of "the number of votes is 5" is the number type data, and the cache data corresponding to the data of "the number of votes is 5" in the cache area is also deleted.

As an example, when the user a deletes the data of which the content is "this is a test article content. - > even" in the database, and it is determined that the data of which the content is "this is a test article content. - > is map type data, the cache data corresponding to the data of which the content is" this is a test article content. - > also is deleted.

According to the data caching method, when the required data in the database is deleted, the cache data corresponding to the cache region is actively deleted, so that the cleaning operation of invalid cache data in the cache region is guaranteed, the operating pressure of the database is reduced, the operating performance of the database is improved, and excessive cache data are prevented from being stored in the cache region.

To further enhance data consistency, a retry mechanism may be added. In some embodiments of the present application, target cache data in an operation failure state in a cache region may be determined, the target cache data is placed in a retry deletion cache queue, and a continuous retry deletion operation is performed on the target cache data in the retry deletion cache queue until the target cache data is completely deleted.

It should be noted that, in the embodiment of the present application, the operation failure may include: modification failure and deletion failure. If the cache data has any one of modification failure and deletion failure, the cache data is put into a retry deletion cache queue.

In the embodiment of the application, if the operation is a modification operation, the modification operation is performed on the cache data, if the result obtained by the modification is the modified cache data, the processing operation is proved to be successful, and if the result obtained by the modification is not the modified cache data, the processing operation is proved to be failed; if the processing operation is a delete operation, the delete operation is performed on the cache data, if the delete result is that the cache region does not have the cache data, the processing operation is proved to be successful, and if the delete result is that the cache region still has the cache data, the processing operation is proved to be failed. The buffered data can be put into a retry deletion buffer queue at this time, so as to perform continuous retry attempt deletion on the buffered data.

As an example, when a user needs to delete "ticket number 5" of the cached data, and finds that the "ticket number 5" of the cached data cannot be deleted, the "ticket number 5" of the cached data is put into a retry deletion cache queue, and the "ticket number 5" of the cached data is continuously tried to be deleted in the retry deletion cache queue, and then after a plurality of attempts, the "ticket number 5" of the cached data is deleted.

As an example, when a user needs to perform a modification operation on the cache data "which is a piece of test article content. -. no way to be modified," the cache data "which is a piece of test article content. -. no way to be modified is found, and finally the cache data" which is a piece of test article content. -. is put into a retry deletion cache queue, and the cache data "which is a piece of test article content. -. the" is continuously tried to be deleted after the retry deletion cache queue is retried, and then the cache data "which is a piece of test article content. -. is deleted after a plurality of attempts.
