In the embodiment of the present application, when the relevant business datum of seniority among brothers and sisters scene changes, according to ordered set data knot
Structure will need to be synchronized to memory type database for the synchronous data of seniority among brothers and sisters scene, to utilize ordered set data structure
Sequentialize commands are ranked up in memory type database for seniority among brothers and sisters the data cached of scene, obtain the corresponding row of seniority among brothers and sisters scene
Row data.On the one hand, it needs not rely on asynchronous thread and obtains ranking data from service database, therefore is with higher real-time
Property, and it is offline in service database or when being abnormal, it will not be affected；On the other hand, type database is strong based on memory
The sorting query efficiency of big handling capacity and ordered set data structure superelevation, additionally it is possible to which the seniority among brothers and sisters inquiry for meeting high concurrent is wanted
It asks.
It describes in detail below to the householder method of the data seniority among brothers and sisters of the embodiment of the present application.
The embodiment of the present application according to ZSet data structure (a kind of ordered set data structure), will specifically be needed for seniority among brothers and sisters
The synchronous data of scene are synchronized in memory type database.
ZSet data structure belongs to key-value one of which manifestation mode.It includes: key, member and score tri-
Kind of element, under each key, member is corresponding with a score.The characteristics of ZSet data structure, can be based on score value
Size sorts to member.
The characteristics of based on ZSet data structure, the embodiment of the present application define seniority among brothers and sisters period, seniority among brothers and sisters object to seniority among brothers and sisters scene
With seniority among brothers and sisters three attribute of attribute value, respectively as the key key, member member and score score of ZSet data structure.
The subsequent sequentialize commands to the data cached execution ZSet data structure after synchronizing, can be to rank the period as constraint
Condition is ranked up seniority among brothers and sisters object according to the size of seniority among brothers and sisters attribute value, obtains the corresponding ranking data of seniority among brothers and sisters scene.
Wherein, memory type database includes: target row for the required data synchronous to service database of seniority among brothers and sisters scene
The corresponding variate-value of seniority among brothers and sisters attribute value of row object (target seniority among brothers and sisters object belongs to the seniority among brothers and sisters object in seniority among brothers and sisters scene)；
When executing above-mentioned steps 104, specifically includes the following steps:
Step 1041, if the key of memory type database has the field value in current seniority among brothers and sisters period, it is based on variate-value, it is right
Target ranks field value of the object in the score that currently the seniority among brothers and sisters period corresponds to memory type database and modifies；
Step 1042, if the key of memory type database will currently be ranked week there is no the field value in current seniority among brothers and sisters period
The field configuration of phase is based on variate-value into the key of memory type database, to target seniority among brothers and sisters object within a upper seniority among brothers and sisters period
The field value deposited in the score of type database is calculated, and calculated result is written to target seniority among brothers and sisters object and is ranked currently
Period corresponds in the score of memory type database.
It should be understood that the memory type database in the embodiment of the present application can save the ranking data in multiple seniority among brothers and sisters periods, i.e.,
Field value containing multiple seniority among brothers and sisters periods in the Key of memory type database.
Alternatively, the memory type database in the embodiment of the present application can also refer to the seniority among brothers and sisters number for retaining a nearest seniority among brothers and sisters period
According to.That is, after having executed above-mentioned steps 1042, also further delete target seniority among brothers and sisters object a upper seniority among brothers and sisters period correspond to key,
Field value in member, score.
Certainly, if the member of memory type database does not have the field value of target seniority among brothers and sisters object, the embodiment of the present application
Further the field value of target seniority among brothers and sisters object can also be configured into the member of memory type database.
It should be noted that the ordering instruction of ZSet data structure is first according to the field value size of score to member
It is ranked up, when score field value size is identical, according further to member field value with permanent order from big to small
Member is ranked up.
Therefore, the embodiment of the present application can pass through setting in the member configuration seniority among brothers and sisters object for memory type database
The size of the field value of object is ranked, to realize more specifically sequence effect.
For example, the seniority among brothers and sisters object that the application ranks in scene is divided into high priority seniority among brothers and sisters object and low priority seniority among brothers and sisters pair
As.
When seniority among brothers and sisters attribute value is identical, the ranking that high priority ranks object should be located at the ranking of low priority seniority among brothers and sisters object
Before.
Accordingly, the number that numerical value expression can be used in the embodiment of the present application represents seniority among brothers and sisters object, the seniority among brothers and sisters of high priority
The number numerical value of object is greater than the number numerical value of the seniority among brothers and sisters object of low priority.
In the member configuration seniority among brothers and sisters object for memory type database, the number of object can will be ranked as seniority among brothers and sisters pair
The field value of elephant is written into member.
Priority body using the user in operation system as seniority among brothers and sisters object as example, in actual scene, between user
Present operation system side, operation system can generally give number of its user configuration as user identifier, different preferential to distinguish
Grade.
It therefore, is reduction procedure, the embodiment of the present application can be using multiplexing service system as the number of user configuration, as user
Field value in the member of memory type database.
Certainly, if operation system to the user identifier of its user configuration is not the number indicated with numerical value, the application is real
It applies example and is further based on preset compiler algorithm, the number indicated with numerical value will be compiled into the user identifier that family configures.
It should be understood that the priority of user is higher, then the numerical value of the number of compiler algorithm compiling is bigger；The priority of user is got over
Low, then the numerical value of the number of compiler algorithm compiling is smaller.
What needs to be explained here is that the ordering instruction of ZSet data structure can only be with the field value of member from big to small
Permanent order is ranked up.
The corresponding number size of user depends on operation system, the number for the high-priority users that may determine in practice
The number of low first grade user can be less than, will lead in this way when the ordering instruction based on ZSet data structure is ranked up, it is low excellent
The ranking of first grade user is located at before the ranking of high priority.To avoid this problem from occurring, it is set larger to can be used one
Value subtracts field value of the corresponding number of user as user in member.
For example it is 1 that operation system, which is the number value that high-priority users configure, the number value of low priority user configuration is
2, then predetermined value can take 10, and field value of the high-priority users in member is 10-1=9, and low priority user exists
Field value in member is 10-2=8.Exist since field value of the high priority in member is greater than low priority user
Field value (9 > 8) in member, therefore in the identical situation of the two seniority among brothers and sisters attribute value, high-priority users can come low
Before priority users.
In specific implementation, the embodiment of the present application can construct the configuration process of the field value of seniority among brothers and sisters object, the configuration
Journey is used to subtract the corresponding number of seniority among brothers and sisters object using predetermined value, and configures calculated result as the field value of seniority among brothers and sisters object
Into the member of memory type database；Wherein, it is to rank the number of the number of object configuration that predetermined value, which should be greater than operation system,
It is worth the upper limit, to avoid there is the case where negative value.
After obtaining configuration process, it can be based on above-mentioned configuration process, the field value of arbitrary target seniority among brothers and sisters object is configured
Into the member of memory type database.
Accordingly, target is read from memory type database and rank object, then need to rank target object in member
Middle field value reverts back corresponding number, to correctly identify that target ranks object based on number.That is, the embodiment of the present application
Householder method further include:
The reading process of the field value of building seniority among brothers and sisters object, the reading process are used to subtract seniority among brothers and sisters pair using upper predetermined value
As the field value in the member of memory type database, the corresponding number of seniority among brothers and sisters object is obtained；Wherein, seniority among brothers and sisters object is corresponding
Number the reading result of the field value as seniority among brothers and sisters object.
For example, target seniority among brothers and sisters object is encoded to 10, set value 100 is based on above-mentioned configuration process, and target ranks object
Field value in the member of memory type database is 100-10=90.
It, can through above-mentioned reading process when reading the field value marked and rank object in the member of memory type database
To use set value 100 to subtract field value 90 of the target seniority among brothers and sisters object in member, accurate reproduction returns target seniority among brothers and sisters object
Coding.
It should be understood that the scheme of the embodiment of the present application can be according to operation system to the configuration feature of user identifier, decision is
No building seniority among brothers and sisters object is directed to the configuration process and reading process of member.
According to ZSet data structure, synchronous data are needed to be synchronized to memory for seniority among brothers and sisters scene memory type database
After in type database, it can be ranked up by the sequentialize commands of ZSet data structure to data cached, to obtain ranking data.
Specifically, after obtaining seniority among brothers and sisters inquiry request, the field value in current seniority among brothers and sisters period is first determined, and by currently ranking
The field value in period corresponds to the data cached of current seniority among brothers and sisters period to judge that memory database whether there is.
If the key of memory type database has the field value in current seniority among brothers and sisters period, construct currently to rank the word in period
Segment value is constraint condition, the sequentialize commands being ranked up to member according to the size of score；
If there is no the field values in current seniority among brothers and sisters period by the key of memory type database, the above seniority among brothers and sisters period is constructed
Field value is constraint condition, the sequentialize commands being ranked up to member according to the size of score.
In practical applications, the embodiment of the present application can construct ZRank order or ZRevarange order, to data cached
Realize sequence.
By taking ZRank order as an example, the application can instruct the field value according to seniority among brothers and sisters object based on ZRank, and inquiry corresponds to
Ranking.Skiplist skip list inside ZSet is (average O (logN) the worst O (N)) skip list with time complexity
Node carries out span data, and inquiry obtains ranking data.
By taking ZRevarange order as an example, range query, such as 1-100 directly can be realized using ZrevRange order
Name is ranked up seniority among brothers and sisters object according to the sequence of seniority among brothers and sisters attribute value from big to small, obtains first 100 seniority among brothers and sisters to seniority among brothers and sisters object
Data.
It should be understood that the embodiment of the present application can be using key as constraint condition, according to score pairs based on ZSet data structure
The characteristics of member is ranked up, will rank scene in the seniority among brothers and sisters period, seniority among brothers and sisters object and seniority among brothers and sisters attribute value as key,
Member and score, to realize within a certain seniority among brothers and sisters period, the function being ranked up according to seniority among brothers and sisters attribute value to seniority among brothers and sisters object
Energy.Mapping relations are simple between key, member and score, i.e., also can be realized when box lunch data volume grade is huge efficiently quickly
Sequence, it is that the data structure of other key-value can not reach that performance is brilliant.
Below with reference to practical application, the process of the householder method of application embodiment is introduced.
Illustratively, the operation system in this practical application is metal system, is configured with Mysql database and Redis number
According to library.Wherein, Mysql database is as service database；Redis database is as memory type database, for seniority among brothers and sisters scene,
Using ZSet data structure.
Assuming that seniority among brothers and sisters scene is ranked for the remaining sum of user, the seniority among brothers and sisters period is week, as ZSet data structure
key；Seniority among brothers and sisters object is user, the member as ZSet data structure；Seniority among brothers and sisters attribute value is remaining sum value, as ZSet data knot
The score of structure.
This practical application can be updated Redis database using two ways.
A kind of mode is obtained from Mysql database and is needed for seniority among brothers and sisters scene using the asynchronous thread being periodically executed
Synchronous data, which is as shown in Fig. 2, main flow includes:
When meeting the trigger condition being periodically executed, the pipelined data of full dose is obtained from Mysql database.
Determine the key value (field value) in current seniority among brothers and sisters period, i.e. this week corresponding Key value.
Based on the key value in preceding seniority among brothers and sisters period, it is synchronous that data are carried out to Redis database by the pipelined data of full dose.
Empty in Redis database it is upper one seniority among brothers and sisters the period it is data cached.
Since in the method, the synchrodata of Redis database derives from service database, therefore can be from business datum
The pipelined data that library obtains full dose carries out balance updates to users all in Redis database can also be right after the completion of update
A upper seniority among brothers and sisters the data cached of period is deleted.
Another way is, as soon as there is the remaining sum of user to change in operation system, carries out to Redis database same
Step, which is as shown in figure 3, main flow includes:
When the remaining sum of target user in operation system changes, target user's remaining sum is obtained from operation system
Variate-value.
Determine the key value (i.e. this week corresponding key value) in current seniority among brothers and sisters period.
Judge whether redis database deposits target with the presence or absence of the key value and redis database in current seniority among brothers and sisters period
The member value of user.
If there is no the key values in current seniority among brothers and sisters period for redis database, call Zadd instruction in redis database
The key value in current seniority among brothers and sisters period is configured in key.
If the member value of target user is not present in redis database, the Zadd of ZSet data structure is called to instruct
The member value of target user, and the variate-value of the remaining sum based on target user are configured in the member of redis database, are matched
Set field value of the target user in the score of current period.
If redis database has the key value in current seniority among brothers and sisters period and the member value of target user, call
The incrementScorem order of ZSet data structure, according to the variate-value of the user balance, to the user in current period pair
The score value answered is adjusted.
After being updated by Fig. 2 and method shown in Fig. 3 to Redis database, it can be obtained based on sequentialize commands
The ranking data of Redis database, corresponding process are as shown in Figure 4, comprising:
Obtain the seniority among brothers and sisters inquiry request ranked with remaining sum size to user.
Determine the key value (i.e. this week corresponding key value) in current seniority among brothers and sisters period.
Judge redis database with the presence or absence of the key value in current seniority among brothers and sisters period.
It is right based on the key value in current seniority among brothers and sisters period if redis database has the key value in current seniority among brothers and sisters period
The Page sorting of the data cached execution ZSet data structure of redis database instructs, and obtains the ranking data of Pagination Display；And
The ranking data of Pagination Display is subjected to unserializing processing, and parsing, assembling, to show in operation system.
If redis database be there is no the key value in current seniority among brothers and sisters period (until current time, the ranking data of this week
Do not change with upper week list data), it is determined that the kye value in a upper seniority among brothers and sisters period, and judge whether redis database is deposited
In the key value in a upper seniority among brothers and sisters period；
If there are the key values in a upper seniority among brothers and sisters period for redis database, right based on the key value in a upper seniority among brothers and sisters period
The Page sorting of the data cached execution ZSet data structure of redis database instructs, to the ranking data of Pagination Display；And it will
The ranking data of Pagination Display carries out unserializing processing, and parsing, assembling, to show in operation system.If redis number
According to library, there is no the key values in a upper seniority among brothers and sisters period, then execute abnormality processing (such as alarm, recording exceptional log).
Based on above-mentioned design, data page sort method provided by the embodiments of the present application is right by step shown in Fig. 2
Redis database carries out regularly full dose and updates, and is based on step shown in Fig. 3, carries out real-time increment to Redis database
It updates, so that the ranking data for guaranteeing that Redis database provides is consistent with practical scene, is mentioned outward with the smallest performance consumption
For ranking query service.Only need the key for increasing Redis database that more multi-functional extension can be realized simultaneously, such as simultaneously

Mark seniority among brothers and sisters object is in the score that currently the seniority among brothers and sisters period corresponds to the memory type database.
It should be understood that the memory type database in the embodiment of the present application can save the ranking data in multiple seniority among brothers and sisters periods, i.e.,
Field value containing multiple seniority among brothers and sisters periods in the Key of memory type database.
Alternatively, the memory type database in the embodiment of the present application can also refer to the seniority among brothers and sisters number for retaining a nearest seniority among brothers and sisters period
According to.That is, synchronization module 52 ranks object after currently ranking in the score that the period corresponds to memory type database in write-in target,
It also further deletes target seniority among brothers and sisters object and corresponded to field value in key, member, score in a upper seniority among brothers and sisters period.
Certainly, if the member of memory type database does not have the field value of target seniority among brothers and sisters object, the embodiment of the present application
Synchronization module 52 can also further configure the field value of target seniority among brothers and sisters object into the member of memory type database.
It should be noted that the ordering instruction of ZSet data structure is first according to the field value size of score to member
It is ranked up, when score field value size is identical, according further to member field value with permanent order from big to small
Member is ranked up.
Therefore, the synchronization module 52 of the embodiment of the present application for memory type database member configuration seniority among brothers and sisters object when,
It can be by the size of the field value of setting seniority among brothers and sisters object, to realize more specifically sequence effect.
For example, the seniority among brothers and sisters object that the application ranks in scene is divided into high priority seniority among brothers and sisters object and low priority seniority among brothers and sisters pair
As.
When seniority among brothers and sisters attribute value is identical, the ranking that high priority ranks object should be located at the ranking of low priority seniority among brothers and sisters object
Before.
Accordingly, the number that numerical value expression can be used in the embodiment of the present application represents seniority among brothers and sisters object, the seniority among brothers and sisters of high priority
The number numerical value of object is greater than the number numerical value of the seniority among brothers and sisters object of low priority.
Synchronization module 52 can will rank the number of object in the member configuration seniority among brothers and sisters object for memory type database
Field value as seniority among brothers and sisters object is written into member.
Priority body using the user in operation system as seniority among brothers and sisters object as example, in actual scene, between user
Present operation system side, operation system can generally give number of its user configuration as user identifier, different preferential to distinguish
Grade.
Synchronization module 52 can be using multiplexing service system as the number of user configuration, as user in memory type database
Field value in member.
Certainly, if operation system to the user identifier of its user configuration is not the number indicated with numerical value, synchronization module
52 can also be based further on preset compiler algorithm, and the number indicated with numerical value will be compiled into the user identifier that family configures.
What needs to be explained here is that the ordering instruction of ZSet data structure can only be with the field value of member from big to small
Permanent order is ranked up.
The corresponding number size of user depends on operation system, it is thus possible to the high priority determined from business system side
The number of user can be less than the number of low first grade user, will lead to arranged in the ordering instruction based on ZSet data structure in this way
When sequence, the ranking of low priority user is located at before the ranking of high priority.To avoid this problem from occurring, synchronization module 52 can
To use a set the larger value to subtract field value of the corresponding number of user as user in member.
For example it is 1 that operation system, which is the number value that high-priority users configure, the number value of low priority user configuration is
2, then predetermined value can take 10, and field value of the high-priority users in member is 10-1=9, and low priority user exists
Field value in member is 10-2=8.Exist since field value of the high priority in member is greater than low priority user
Field value (9 > 8) in member, therefore in the identical situation of the two seniority among brothers and sisters attribute value, high-priority users can come low
Before priority users.
In specific implementation, synchronization module 52 can construct the configuration process of the field value of seniority among brothers and sisters object, the configuration process
It is configured for using a predetermined value to subtract the corresponding number of seniority among brothers and sisters object, and using calculated result as the field value of seniority among brothers and sisters object
Into the member of memory type database；Wherein, it is to rank the numerical value of the number of object configuration that predetermined value, which is greater than operation system,
The upper limit.
After obtaining configuration process, synchronization module 52 is based on the configuration process, and arbitrary target can be ranked to the word of object
Segment value is configured into the member of memory type database.
Accordingly, target seniority among brothers and sisters object is read from memory type database then needs to rank target object in member
Field value reverts back corresponding number, to correctly identify that target ranks object.That is the synchronization module 52 of the embodiment of the present application
Also particularly useful for:
The reading process of the field value of building seniority among brothers and sisters object, the reading process are used to subtract row using the predetermined value
Field value of the row object in the member of the memory type database obtains the corresponding number of seniority among brothers and sisters object；Wherein seniority among brothers and sisters pair
Reading result as corresponding number as the field value of seniority among brothers and sisters object.
For example, target seniority among brothers and sisters object is encoded to 10, set value 100 is based on above-mentioned configuration process, and target ranks object
Field value in the member of memory type database is 100-10=90.Mark seniority among brothers and sisters object is being read by above-mentioned reading process
When field value in the member of memory type database, set value 100 can be used and subtract target seniority among brothers and sisters object in member
In field value 90, accurate reproduction return target seniority among brothers and sisters object coding.
In practical applications, whether synchronization module 52 can be determined according to operation system to the configuration feature of user identifier
Building seniority among brothers and sisters object is directed to the configuration process and reading process of member.
According to ZSet data structure, synchronous data are needed to be synchronized to memory for seniority among brothers and sisters scene memory type database
After in type database, building module 34 can construct the sequentialize commands of ZSet data structure.
As exemplary introduction, constructs module 34 and is specifically used for:
After obtaining seniority among brothers and sisters inquiry request, the field value in current seniority among brothers and sisters period is first determined, and pass through the currently seniority among brothers and sisters period
Field value judges the memory database with the presence or absence of corresponding data cached.
