First below be directed to this specification relates to technical term simply introduced.
Database access request has the enterprise of data management demand to be stored in the data of itself as stated in the background art
In the equipment that database service enterprise provides, so when thering is the enterprise of data management demand to access the data of its own, first
The database server transmission data access request to database service enterprise is needed, the data of its own can just be accessed.
Data access request can be data read request, can be according to after database server receives data read request
Data read request, by the data-pushing corresponding to data read request to the terminal of transmission data read request so that terminal user
The corresponding data of data read request can be checked by terminal.For example, terminal A is sent to database server for data x's
Data read request, then database server can find data x, and data x is pushed to terminal A.
Data access request can also be data write request, can be by after database server receives data write request
According to data write request, corresponding data write operation, such as increase, deletion, the modification of data are executed.Illustratively, terminal B is to number
The data write request for deleting data y is sent according to library server, then database server can find data y, and by data y from
It is deleted in database.
QPS, Chinese are known as query rate per second, can be understood as in present specification：It is looked forward to for each database service
Each user of industry, the database server quantity per second for handling the corresponding database access request of the user.For example, for using
The quantity of the corresponding database access request of family X, database server processing user X per second is M, then the user couple within the second
The QPS answered is M.
The different user setting difference that database service enterprise is serviced for it is cannot be satisfied in order to solve the prior art
The problem of demand of QPS limitations, an embodiment of the present invention provides a kind of request processing method, device, electronic equipment and storages to be situated between
Matter.
A kind of request processing method is provided for the embodiments of the invention first below to describe in detail.
Firstly the need of explanation, a kind of request processing method that the embodiment of the present invention is provided can be applied to data
Library service equipment, i.e., above-mentioned database server.In the case of one kind, which is setting for storing data
It is standby.In another case, can be the control server in data base cluster system, or agency's clothes in the database server
Business device (proxy), database server itself does not store data, but it can be communicated with the database node of storage data
Letter；For example, above-mentioned database is redis databases, data base cluster system includes control server and multiple redis sections
Point, control server are communicated with each redis nodes, and control server can be used for receiving database access request, and can
Received data library access request is transmitted to corresponding redis nodes.
As shown in Figure 1, a kind of request processing method provided in an embodiment of the present invention, including：
S101：Receive target database access request.
It is understood that the sender of target database access request is database server corresponding end herein
End, it is clear that, which belongs to the aforementioned enterprise for having data management demand, also, each received by database server
A database access request can be so-called target database access request in the embodiment of the present invention.In addition, as previously mentioned,
Target database access request herein can be database read request, can also be database write request, be even other
The request of classification, the embodiment of the present invention do not limit the concrete type of target database access request herein.
S102：Judge whether the first count value is less than 1；Wherein, the first count value is to be asked for target database access
The count value set by corresponding target user, the first count value is asked to be arranged to the first present count at interval of the first preset duration
Value.
It should be noted that target user belongs to the object that database service enterprise is serviced, and in the case of a kind of, database
The object that service enterprise is serviced is individual, then the target user is the terminal use for sending the target database access request
Person；In another case, the object that database service enterprise is serviced is enterprise, mechanism etc., then the target user is enterprise's machine
Structure etc., target user is not equivalent to the terminal user for sending the target database access request in the case of this, for example, the mesh
Mark user is company A, and the employee a under company A is by terminal to database server transmission data library access request.
In the embodiment of the present invention, the first count value that target user is configured is a variable, the first count value at interval of
First preset duration will be arranged to the first default value, wherein first default value is the positive number more than 1, in addition, should
First preset duration and the first default value can be arranged according to actual conditions, and it is first pre- that the embodiment of the present invention does not limit this
If the concrete numerical value of duration and the first default value, for example, the first default value of setting is 50, the first preset duration is 1s
(second).
In practical applications, can according to corresponding to target user the grade of service and/or charge setting above-mentioned first it is pre-
If duration and the first default value, the grade of service and/or charge corresponding to target user are higher, and the first preset duration is arranged
Shorter and/or the first default value is bigger.It, then can be with for example, the grade of service corresponding to target user A is higher than target user B
It sets corresponding first default values of target user B to the 50, first preset duration and is set as 1s, target user A is corresponding
First default value is set as the 80, first preset duration and is set as 1s.
If the judging result of step S102 is no, step S103 is executed：Handle the target database access request.
In embodiments of the present invention, only in the case where the judging result of step S102 is no, database server is
It can go to handle the target database access request, and in the case where the judging result of step S102 is to be, database server
The target database access request will not be handled, for example, database server can refuse the target database access request.
It is appreciated that in the case where the judging result of step S102 is to be, if database server directly refuses mesh
Database access request is marked, that is, shows that the target database access request cannot respond, in the embodiment of the present invention, in order to enable
Each database access request can be handled by database server, i.e., each database access request can be rung
It answers, as a kind of optional realization method of the embodiment of the present invention, in the case where the judging result of step S102 is to be, above-mentioned side
Method can also include：
It is spaced the second preset duration, returns to execution is above-mentioned to judge the step of whether the first count value is less than 1 (S102).
The specific size of second preset duration can be based on actual demand and set, and the embodiment of the present invention does not limit second
The specific size of preset duration.
The judging result of step S102 is yes, shows that current first count value is less than 1, but the first count value is at interval of the
One preset duration can be arranged to the first default value, so the first count value after current time when the second preset duration differs
Surely it is less than 1, if first count value of moment is not less than 1, server can handle the target data in the time data library
Library access request.
Illustratively, it is assumed that at the first moment, the first count value is 0, then determines step S102's at the first moment
Judging result is yes；A length of 1s when preset second level, 1s was referred to as the second moment after the first moment, at the first moment to second
Certain moment between moment, the first count value are reset as 50.So database server executes step again at the second moment
Rapid S102, the result that judges to be likely to of step S102 is no at this time, then the target data access request can be by database service
Handled by device.
It, can be with although some database access requests cannot be by timely processing it is appreciated that in this realization method
Ensure that each database access request can be handled by database server.
As previously mentioned, in the case of one kind, which is equipment for storing data, in this case, data
The server process target database access request in library can be understood as：Database server is according to target database access request
Corresponding database manipulation is executed, for example, the target database access request is to be directed to the write request of data a, then database
Server executes the operation that data a is written to database.
In another case, can be the control server in data base cluster system, data in the database server
Library group system includes control server and multiple database nodes for storing data, in this case, database service
Device handles the target database access request and can be understood as：The target database access request that database server will be received
It is transmitted to corresponding database node.For example, control server communication is connected with 10 redis nodes, target database accesses
Request is checks that the data of data a check request, then database server processes target database access request is：It finds out
The redis nodes that data a is stored, and target database access request is transmitted to found redis nodes.
S104：Updating the first count value is：Current first count value with 1 difference.
In embodiments of the present invention, the first count value at interval of the first preset duration in addition to being arranged to the first default value
Outside, database server processes are crossed after the corresponding database access request of target user and can also update the first count value and be：
Current first count value with 1 difference.
For example, current first count value is 45, database server is after performing step S103, by the first count value
It is updated to 44.
It should be noted that in actual use, the first count value in the embodiment of the present invention can be default enables
Token quantity in board bucket.In the case, database service enterprise is respectively provided with a token for its each user serviced
Barrel, the token quantity in token bucket is above-mentioned first count value.
Correspondingly, above-mentioned first default value is to be directed in the default target spoke bucket of target user at most accommodate
Token quantity, also, step S104 at this time can be：
It updates and is for the token quantity in the default target spoke bucket of target user：Order in current goal token bucket
Board quantity with 1 difference.
It is appreciated that in embodiments of the present invention, the first count value is arranged to first in advance at interval of the first preset duration
If numerical value, i.e. database server periodically resets to first using the first preset duration as a cycle, by the first count value
Default value.Again since database server often handles the database access request corresponding to a target user, will update
First count value is：Current first count value with 1 difference, so for the database access request corresponding to target user,
Database server can at most handle the first default value within the said one period, to achieve the purpose that QPS is limited.
Can with understanding, in embodiments of the present invention, the QPS values corresponding to target user be above-mentioned first default value with
The ratio of first preset duration.And identical in the first preset duration, the first default value is bigger, and QPS values are higher；
Likewise, identical in the first default value, the first preset duration is smaller, and QPS values are higher.
Illustratively, for target user, the first default value is 40, and the first preset duration is 1s.Then in a cycle
Interior, data server can at most handle 40 corresponding database access requests of target user.
From the foregoing, it will be observed that compared with prior art, in scheme provided in this embodiment, database server is only in the first meter
In the case that numerical value is not less than 1, above-mentioned target database access request can be just handled, and since the first count value is at interval of first
Preset duration is arranged to the first default value, and often handles the database access request of a target user, can update first
Count value is：Current first count value and 1 difference, therefore the database access request of database server processes target user
Average speed is：The ratio of first default value and the first preset duration meets database service enterprise and is serviced for it
Different user setting different Q PS limitation demand.
In embodiments of the present invention, on the basis of embodiment of the method shown in Fig. 1, as shown in Fig. 2, sentencing in step S102
Disconnected result is in the case of being, the above method can also include：
S105：Before statistics current time in third preset duration, the total degree that the first count value is less than 1 is judged.
Likewise, the specific size of third preset duration may be set according to actual conditions, the embodiment of the present invention is simultaneously unlimited
Determine the specific size of third preset duration.
For step S105, illustratively, database server, can be with when determining the first count value less than 1 every time
Do primary record；Assuming that third preset duration is 1 hour, then when executing step S105, statistics is found database server
In first 1 hour of current time, the total degree of above-mentioned record is 100 times, i.e., judged in third preset duration before current time
Total degree of first count value less than 1 is 100 times.
S106：Judge whether the total degree reaches the first predetermined threshold value.
Likewise, the specific size of the first predetermined threshold value may be set according to actual conditions, the embodiment of the present invention is simultaneously unlimited
The specific size of fixed first predetermined threshold value.
If the judging result of step S106 is yes, step S107 is executed：Updating the first default value is：Current first is pre-
If numerical value and the second default value and value.
It is appreciated that in embodiments of the present invention, the first default value is also not fixed value, in the judgement of step S106
As a result it is in the case of being, can update the first default value is：Current first default value and the second default value and value.
Certainly, the specific size of the second default value may be set according to actual conditions, and it is default that the embodiment of the present invention does not limit second
The specific size of numerical value.
For step S106 and step S107, illustratively, it is assumed that the first predetermined threshold value is 40, and step S105 is counted
Total degree be 50 times, the first current default value is 50, and the second default value is 10.Obvious, the judgement of step S106
As a result be yes, need at this time execute step S107, i.e., by the first default value be updated to 50 and 10 and value 60.
In the case where the first preset duration is constant, the first default value increases, then increases the corresponding QPS of target user
Value, as previously mentioned, the corresponding QPS values of target user are corresponding with the grade of service of target user, tollbooth, so in reality
In application process, after executing the step S107, database server can also generate new charge for current QPS values and order
It is single, and according to new order charging.Certainly, the specific mode for generating charge order and charging is referred to the prior art, this
Inventive embodiments are not described in detail herein.
Compared with embodiment of the method shown in Fig. 1, in the embodiment of the present invention, target use can be increased automatically according to actual conditions
The QPS values at family, it is ensured that database access request corresponding to target user can by database server timely processing,
It is excessively high to ensure that the QPS values of target user will not be set to simultaneously.
As a kind of optional realization method of the embodiment of the present invention, the case where the judging result of above-mentioned steps S106 is to be
Under, for database server other than executing step S107, the above method can also include the following steps S1：
Step S1：Prompt messages are generated, and the prompt messages generated are fed back into above-mentioned target database
Terminal corresponding to access request.
The prompt messages are that the QPS to prompt target user current is too low, cannot be satisfied the reality of target user
The information of use demand, the embodiment of the present invention do not limit the form of the prompt messages.It is appreciated that prompt messages
After feeding back to the terminal corresponding to above-mentioned target database access request, which can be shown to itself by prompt messages
Display interface on or voice broadcast come out so that target user can grasp the too low problem of current QPS values in time.
For example, carry current QPS values in the prompt messages generated, i.e. the first default value and first it is default when
Long ratio, specifically such as：Current QPS values are 50, then the terminal corresponding to above-mentioned target database access request is receiving report
It, can the display reminding information " alarm on the display interface of itself after alert prompt message：Current QPS values are 50, QPS value mistakes
It is low ".
It should be noted that in practical applications, in the case where the judging result of above-mentioned steps S106 is to be, database
Server can only execute step S1, without executing step S107.In the case, target user is learning current QPS values mistake
When low problem, the request for changing current QPS can be sent to database server by terminal.For example, change QPS's asks
Asking to be：In the case where keeping first to preset constant, the first current default value is increased to current 2 times.
As previously mentioned, after the corresponding QPS values of target user are raised, the corresponding charge of target user also can accordingly rise
Height, in the embodiment of the present invention, in order to ensure that QPS values are improved automatically in the range that target user is subjected to, as this hair
A kind of optional realization method of bright embodiment is in the first default value of above-mentioned update：Current first default value and second is in advance
If numerical value and value (S107) the step of before, the above method can also include：
Judge current first default value and the second default value and value whether be less than the second predetermined threshold value；
If it is less than the second predetermined threshold value, executing the first default value of above-mentioned update is：Current first default value and
Two default values and value the step of.
I.e. in the present embodiment, on the basis of embodiment of the method shown in Fig. 2, as shown in figure 3, above-mentioned request processing method
Including：
S201：Receive target database access request.
S202：Judge whether the first count value is less than 1；Wherein, the first count value is to be asked for target database access
The count value set by corresponding target user, the first count value is asked to be arranged to the first present count at interval of the first preset duration
Value.
If the judging result of step S202 is no, step S203 is executed：Handle the target database access request.
S204：Updating the first count value is：Current first count value with 1 difference.
If the judging result of step S202 is yes, S205 is executed：Before statistics current time in third preset duration, judge
Go out the total degree that the first count value is less than 1.
S206：Judge whether the total degree reaches the first predetermined threshold value.
If the judging result of step S206 is yes, step S207 is executed：Judge current first default value and second in advance
If whether numerical value is less than the second predetermined threshold value with value.
Likewise, the specific size of the second predetermined threshold value may be set according to actual conditions, the embodiment of the present invention is simultaneously unlimited
The specific size of fixed second predetermined threshold value.In actual use, which can be preset by target user, example
Such as, it is 100 that target user first passes through terminal profile second predetermined threshold value in advance, and the second set predetermined threshold value is sent to
Database server.
If the judging result of step S207 is yes, step S208 is executed：Updating the first default value is：Current first is pre-
If numerical value and the second default value and value.
Certainly, in the case where the judging result of step S207 is no, step S208 is not carried out in database server.
It should be noted that the step S201~S206 and S208 in embodiment of the method shown in Fig. 3 are corresponded to and Fig. 2 institutes respectively
Show that the S101~S106 and S107 in embodiment of the method is identical, the explanation and specific implementation of step S201~S206 and S208
It is referred to embodiment of the method shown in Fig. 2, details are not described herein for the present embodiment.
For step S207 and S208, illustratively, the second predetermined threshold value is 80, and the second default value is 20, it is assumed that when
