Embodiment
Fig. 1 shows a kind of exemplary system architecture diagram, and the system includes：User equipment (User Equipment,
UE application server, database and the application server caching (hereinafter referred to as " caching ")), interacted with user equipment, application
The presence of server buffer is to alleviate the pressure of database.Wherein, application server caching can be the sheet of application server
Ground caches (i.e. the internal memory of application server).The principle for accessing database is as follows：Looked into when user equipment is sent to application server
After the request for asking target data, if the request is that (" first " can be the in a collection of concurrent request to access request first
One) because the target data of inquiry needed for not stored in caching when accessing first, application server needs to hold
Row inquires about the operation of target data from database, and caching is write target data into after target data is inquired first
In.After subsequently received other are used to inquire about the request of above-mentioned target data, then target data can be obtained from caching simultaneously
Return to user equipment.As can be seen that as long as the data in caching are effective, then can be moved without carrying out the access to database
Make, the access action to database only needs performing first once, greatly reduces the access pressure to database.When
So, data cached in order to flexibly update, the data in caching are typically arranged with the out-of-service time (such as：1 day).
UE can be fixed or move.UE is also referred to as another term, such as mobile station (MS), user terminal
(UT), subscriber station (SS), mobile terminal (MT) or wireless device.UE can be such as：Computer, mobile phone, personal digital assistant
(PDA), wrist-watch etc..
In the related art, in the scene of some high concurrents request, it is possible that the data failure in caching shows
As.Such as：When Database Systems just start, the data in caching are sky；Or certain machine (some node in server cluster)
Flow enter for a long time by carrying-off and without request, then caching is by whole failures.After data failure in caching, if
Mass data inquiry request is received in short time, then can skip the action of query caching and directly perform and number is inquired about from database
According to operation, this causes huge pressure to database, or even causes the collapse of database.To solve the above problems, propose
Following technical scheme.
Fig. 2 shows a kind of flow chart for data query method that an exemplary embodiment provides.As shown in Fig. 2 one
In embodiment, this method can be applied to server, and this method comprises the steps：
Step 101：Receive the request for inquiring about target data.The request may come from UE.
Step 103：In response to the request, data query thread corresponding with the target data is inquired about in the buffer
Thread object.If the thread object is inquired, into step 109；If not inquiring the thread object, enter step
Rapid 105.
Wherein, the noun being related to is defined as follows：
Data query thread：For performing a thread of the operation that the target data is inquired about from database.
Thread object：The data related to thread, these data may include but be not limited to：Looked into needed for thread identification, thread
The target data ID of inquiry, all kinds of parameters of thread, readjustment result of thread etc..
Usually, a collection of in the high concurrent inquiry request of same target data, for the request of first entrance,
A new data query thread can be created and deposit in the thread object of the thread in caching.So, please for first
Other requests after asking, then can inquire from caching and be asked at first into fashionable created thread object.Namely
Say, if step 103 does not inquire thread object, it is first request to show the request, if step 103 inquires thread
Object, then it is not first request to show the request.
In one embodiment, the data query thread can be asynchronous thread, so as to be shared by multiple requests, i.e.,
It is multiple to ask into fashionable, can utilize the thread go to obtain needed for inquiry data.But target data is inquired about from database
Operation be only successfully executed once and (i.e. after being successfully executed once, be just no longer performed).When the operation is by success
After execution, data query thread can write the target data inquired in caching.
Step 105：Create data query thread corresponding with the target data.
Step 106：By thread object write-in caching corresponding to the thread of establishment.
Step 107：Start the data query thread.
Step 109：Judge whether the data query thread is successfully started up.If being successfully started up, into step
111；If not successfully started up, return to step 107.
The reason for setting the step 109 is：If other after first inquiry request ask into fashionable, not start number
It is investigated that ask thread and directly obtain the readjustment result of data query thread, and if now data query thread it is not actuated into
Work(, this results in the readjustment result that other requests wait thread always.Finally, follow-up inquiry request is caused to wait down always
Go, business can not continue.
In view of the foregoing, enter in each request inquired about for same data fashionable, be required to attempt to start institute
State data query thread.In order to ensure only to make a successful access to database, it is necessary to rely on the idempotence of thread startup interface.
That is, data query thread, once being successfully started up, follow-up trial start-up operation will not all restart the data query
Thread, only when thread is not successfully started up, it can just restart thread.The idempotence that thread starts interface may rely on
The state of thread, such as：State when thread is created can be original state (INIT), once thread is activated success, then will
Its state is set in execution (RUNNING).After thread is activated successfully, if subsequently again attempting to start same thread,
Because thread finds that oneself state in performing (RUNNING), will no longer carry out start-up operation.
Step 111：Target data is obtained using the data query thread and is returned.
On the step 111, the following two kinds situation can be divided into：
1., for the first request in a collection of concurrent request, after creating thread and starting the thread successfully, can perform
Once to the inquiry operation of database.After target data is inquired from database, the mesh can be returned to user equipment
Data are marked, also, can be write the target data as thread parameter in thread object.
2., other requests for being equally used for inquiring about the target data for entering after first request because first
The request successful execution inquiry operation of database, and the target data found is written to thread object (cached
In) in, then without performing the inquiry operation of database again, but the target data is directly read from caching and is returned to
User equipment, until the out-of-service time arrival of thread.
Certainly, if it is first request start thread failure or access database with search the operation of target data not into
Work(, then enter fashionable in subsequent request, may proceed to start the thread or continues executing with the operation for accessing database, until thread starts
Success or operation are successfully executed.In a word, in the term of validity of thread, only meeting successful execution once grasp by the access to database
Make.
As set forth above, it is possible to a term of validity is set for each thread being created, in favor of data cached renewal.
In one embodiment, after the step 106, methods described can also include：
Step 113：In the out-of-service time (can be a time point or a time slice) of the data query thread
After arrival, the thread object corresponding with the data query thread stored in the caching is deleted.
In other embodiments, the step 113 can be removed.For example, artificial triggering acts to data cached removing.
Fig. 3 shows a kind of processing procedure for tackling high concurrent inquiry request.From figure 3, it can be seen that for one not by
Be stored in caching in target data, when occurring a large amount of requesting queries target data in the short time, first arrival please
Data query thread can be created and thread is put into caching by asking, can be in the short period because creating thread and being put into the operation of caching
Interior completion, therefore during follow-up other request arrival, thread will be no longer created, but inquire reached in first request in the buffer
When the thread that has created.So, no matter for above-mentioned target data concurrent request quantity how many, all will be based at first
The thread that is created obtains data when request reaches.In other words, multiple inquiry requests for same target data, it is final to receive
Hold back the single data query operation in same thread.
It can be seen that by above technical scheme after being activated due to data query thread, it is corresponding with the thread to look into
The operation for asking the target data is only successfully executed once, can be write the target data after running succeeded described slow
In depositing.After subsequently received other are used to inquire about the request of the target data, the target can be directly read from caching
Data, and data base querying target data is avoided, so as to alleviate in the scene of high concurrent request because of the data in caching
Fail and give pressure caused by database.
Fig. 4 shows the flow chart for another data query method that an exemplary embodiment provides.As shown in figure 4,
In one embodiment, this method can be applied to application server, and this method comprises the steps：
Step 201：Receive the request for inquiring about target data.The request may come from UE.
Step 203：In response to the request, data query thread corresponding with the target data is inquired about in the buffer
Thread object.If the thread object is inquired, into step 211；If not inquiring the thread object, enter step
Rapid 205.
Step 205：Create data query thread.
Step 206：By in the thread object write-in caching of the data query thread.
Step 207：Start thread and the operation of the target data is inquired about from database in execution after successfully starting up.
Step 209：The target data inquired is returned to user equipment, and the target data is write and cached.
Wherein, step 207 and step 209 can be after first request reaches, the quilts before second request is not reaching to
Perform.
Step 211：Target data is read from caching and is returned.
Before step 211, the complete step 207 of usual executed and step 209, therefore required target data has been present
In caching, therefore avoid and inquiry operation is performed in database.
Step 213：In the out-of-service time (can be a time point or a time slice) of the data query thread
After arrival, the thread object corresponding with the data query thread stored in the caching is deleted.In other embodiments, should
Step 213 can be removed.
So far, after being activated due to data query thread, the operation of the inquiry target data corresponding with the thread
Only it is successfully executed once, the target data can be being write after running succeeded in the caching.It is subsequently received its
He is used for after inquiring about the request of the target data, and the target data can be directly read from caching, and avoids database
Target data is inquired about, so as to alleviate in the scene of high concurrent request caused by the data failure in caching and to database
Pressure.
In a feasible embodiment, when it is first for target data request reach and create a new thread it
Afterwards, the thread can not be started at once.For example, target is directed to n-th (2≤n, n value can be random, can also specify) is individual
When the request of data reaches, start the thread and go to the operation of data base querying data.Certainly, no matter in which request
Reach and start above-mentioned thread, the operation of target data is finally inquired about in database can only be successfully executed once, and the line
The readjustment result (i.e. target data) of journey can be shared by all requests.
