A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Referring to FIG. 1, it illustrates the flow chart of one embodiment of method for preventing caching from penetrating of the application, the present embodiment
Prevent the method that penetrates of caching to can be adapted for the equipment for having caching, such as there is the server of caching.
As shown in Figure 1, in a step 101, receiving caching query request, judge whether the caching query request is legal；
In a step 102, it if caching query request is legal, inquires and judges whether caching hits caching query request institute
Corresponding data；
In step 103, it if caching is not hit, obtains third party's lock and caching query request is locked；
At step 104, judge whether caching query request successfully obtains third party's lock, wherein third party's lock has
Default release time；
In step 105, if successfully obtaining third party's lock, the corresponding data of caching query request are submitted on access backstage
To caching, and the semaphore that data are arranged is to have cached.
In the present embodiment, for step 101, the device for preventing caching from penetrating receives the caching query request of user, and
Judge whether the request is legal.Later, for step 102, if the caching query request it is legal, inquire and judge caching in be
No there are above-mentioned caching queries to request requested data, that is, inquires and judge whether caching hits.Later, for step 103,
If caching obtains third party's lock and locks to caching query request, the quantity of lock is limited without hitting corresponding data
, the request for only obtaining third party's lock is able to access that backstage continues to inquire, and the request that third party's lock has not been obtained cannot visit
Backstage is asked, so that guaranteeing is not in that caching penetrates in the case where distributed system or high concurrent.
Then, for step 104, judge whether caching query request successfully fights for third party's lock, third party's lock has
Default release time, wherein the release of third party's lock is uniformly processed by third party, such as the can be discharged by way of time-out
Tripartite's lock, there is no limit herein by the application.It, can be with for successfully getting the request of third party's lock finally, for step 105
Accessing backstage and the data of request are submitted in caching the semaphore for caching, and the data being arranged is to have cached.
The method of the present embodiment is by first carrying out legal judgement to request, so that some illegal requests are filtered out, it
It inquires whether legal request is buffered hit afterwards, is not buffered life if not hitting and limiting in such a way that third party locks again
In request access to backstage, so as to avoid well caching penetrate the case where.
With further reference to Fig. 2, it illustrates the another kinds that one embodiment of the application provides to prevent from caching the method penetrated
Flow chart.The step that the method for the present embodiment is further limited primarily directed to the additional step after the step 104 in flow chart 1
Rapid flow chart.
As shown in Fig. 2, in step 201, if caching query request is failed to obtain third party's lock, inquiring the signal of data
Whether amount is to have cached；
In step 202, if semaphore is to have cached, query caching.
In the present embodiment, the request is inquired for not getting the request of third party's lock successfully for step 201
Whether the semaphore of corresponding data is to have cached.It later, is that the data cached can direct query caching for semaphore
Obtain corresponding data.
Whether the method for the present embodiment is to have cached by inquiry semaphore, can find quickly and semaphore was arranged as
The data of caching reduce query time so as to faster hiting data.
In some alternative embodiments, the above method further include: cached if not checked in default time-out time
Semaphore when, then direct query caching.The method of the present embodiment is spinned by being arranged while checking semaphore, is more than certainly
If also not detecting semaphore after the default time-out time of rotation, it will direct query caching, to prevent from not delaying at all
It deposits and wastes the excessive time in the data of semaphore.
In further alternative embodiment, semaphore has preset expiration time, method further include: if the letter cached
Number amount is more than the preset expiration time there are the time, then erasure signal amount and corresponding data cached.Thus will not be same in system
When there are many semaphores, reduce the query time of semaphore.
With further reference to Fig. 3, another provided it illustrates one embodiment of the application prevents from caching the method penetrated
Flow chart.Flow chart of the flow chart of the present embodiment primarily directed to the refinement step of step 101 in flow chart 1.
As shown in figure 3, in step 301, the default effective range requested in conjunction with Bloom filter limitation caching query；
In step 302, caching query request is judged whether in default effective range, if in default effective range
It is inside then legal, it is illegal if being not in effective range.
In the present embodiment, for step 301, Bloom filter, and benefit be may include in the device for preventing caching from penetrating
It is located in default effective range with Bloom filter limitation caching query request.For step 302, judge that caching query request is
It is no, if being in, to judge that the request for legitimate request, is preset in effective range if being not at this in default effective range,
Then judge the request for illegal request.
Further, after above-mentioned steps 101 judge whether caching query request is legal, the above method further include: if
Caching query request is illegal, then returns to mistake and abandon caching query request.
The present embodiment limits the effective range of request by introducing Bloom filter, judges whether the parameter of request closes
Method, and the request of discord hair is filtered out in advance, so as to prevent malicious requests well, reduce the processing of subsequent module
Amount, is effectively prevented caching and penetrates.
In some alternative embodiments, before receiving caching query request, method further include: hot spot data is carried out
Data preheating.To can first be preheated to hot spot data before project is online, to prevent online in a flash because slow
Deposit data directly results in caching for sky and penetrates.
In other optional embodiments, is inquiring and judging whether caching hits the corresponding number of caching query request
According to later, method further include: if cache hit, the corresponding data of return cache inquiry request.For the data of cache hit,
Data corresponding to return cache inquiry request, entire scheme form the scheme for completely preventing caching from penetrating and responding.
It should be noted that above method step be not limited to each step execute sequence, in fact, certain steps
It may be performed simultaneously or to execute with the opposite sequence that step limits, there is no limit herein by the application.
Below to some problems encountered in the implementation of the present invention by description inventor and to finally determination
One specific embodiment of scheme is illustrated, so that those skilled in the art more fully understand the scheme of the application.
Inventor has found that defect existing in the prior art is mainly led by following reason during realizing the application
It causes:
1) malicious traffic stream can not be prevented: although the problem of caching and L2 cache can be with effective solution cache hits,
It is that caching caused by can not handling high concurrent or malicious traffic stream well penetrates.
2) technology complexity itself is high: plus the processing of lock, it appears that the peak value of flow when can scabble high concurrent.But it locks
Processing itself be exactly troublesome thing.
3) under the distributed scene of multi-load, the presence of third party's lock also results in the decline of performance.It deletes for when
Except lock and a stubborn problem.
4) assisted with the technology of other field, can not fundamentally prevent caching from penetrating: token bucket algorithm is originally for solving
Certainly the problem of current limliting, the caching caused by reply high concurrent there is penetrated with certain effect.But artificially the degree of control flow is not
Be affectedly bashful well, and token bucket algorithm is only reduction of number of concurrent amount, that is to say, that can still exist it is a certain number of request penetrate it is slow
It deposits.
Wherein, token bucket algorithm (Leaky Bucket) is traffic shaping in network world (Traffic Shaping) or speed
A kind of algorithm being commonly used when rate limitation (Rate Limiting), its main purpose are that control data are injected into network
Rate, the burst flow on smooth network.Token bucket algorithm provides a kind of mechanism, by it, burst flow can be shaped with
Just a stable flow is provided for network.Leaky bucket can be regarded as the single server queue for having constant service time,
If leaky bucket (packet caching) is overflowed, data packet can be dropped.
In a network, token bucket algorithm can control the flow output speed of port, and the burst flow on smooth network is realized
Traffic shaping, to provide a stable flow for network.Token bucket algorithm forces the output speed of a constant but regardless of defeated
Enter the sudden of data flow.When inputting idle, which does not execute any movement；Host is infused in each timeslice to network
Enter a data packet, therefore produces consistent data flow, the flow of smooth burst；When data packet has identical size
It waits (such as ATM cell), the working mechanism that each timeslice transmits a data packet does not have any problems.But for variant pack
Long, there may be some problems for this working mechanism, at this point, the byte of preferably each timeslice transmission fixed number.Such as: such as
The each timeslice of fruit transmits 1024 bytes, then a timeslice allows to transmit the packet of 1024 bytes, two 512 bytes
The packet of packet or four 256 bytes.
Inventor also found that, in order to solve drawbacks described above existing in the prior art, the portioned product of the prior art may
It is solved by following method:
Above several technologies are often combined in industry, to achieve the effect that prevent caching from penetrating, for example, being applied in combination slow
Deposit preheating, locking, bloom filter etc..
It in computer field, speaks of and resource is fought for, generally all only will recognize that simple locking or controlled using queue
The mode of flow, so being less susceptible to expect the scheme of the application.
The scheme of the application, which is mainly started with from the following aspects, to be designed and optimizes:
Firstly, the case where causing caching to penetrate is varied, penetrated to perfectly solve the caching under all scenes, really
Need to be applied in combination various technologies in fact.However, it is desirable to guarantee as far as possible simple, effective.
It prevents malicious traffic stream: using parameter verification+bloom filter, but passing through verification, malicious traffic stream is uniformly referred to
To fixed caching.
It reduces implementation complexity: the complexity that there is height in itself is locked, because you need to consider various exceptions
Influence of the situation to lock.Problem is discharged by shelving lock the most complicated, reduces the implementation complexity of entire scheme.
Improve performance: that reduces lock fights for number.
Prevent it is some can not basic solution to problem be carried out: without using the scheme alleviating caching and penetrating, for example, limit
The thinking (token bucket algorithm) of stream.
Referring to FIG. 4, it illustrates the specific flow charts of one scheme of the application.
As shown in figure 4, the scheme of the application mainly comprises the steps that
1) before project is online, need first to preheat hot spot data, this be in order to prevent it is online in a flash because
For it is data cached be that sky causes to penetrate.
2) any requested next, first determine whether its parameter is legal, in conjunction with the effective of bloom filter limitation request
Illegal request is filtered out in advance, prevents malicious requests by range.
3) query caching, if hit directly returns the result；If do not hit, need to guarantee by third party's lock
It caches and penetrates in the case where distributed system or high concurrent.
4) release locked is uniformly processed by third party (here by time-out release).
5) request of lock is fought for, it will access backstage, and caching is submitted the data to, setting signal amount is to have delayed
It deposits.
6) in the request for not getting lock, the mode of semaphore is checked using spin & to reduce fighting for for lock, raising property
Energy.
7) spin setting time-out time, when semaphore being also not detected at the appointed time, it will direct query caching.
Wherein, it should be noted that:
1, spin lock is present in single association's journey, and acquisition opportunity is not rob to account for third party and lock it in association's journey confirmation
Afterwards, by assisting Cheng Benshen to spin and checking semaphore, number is fought for for what third party locked to reduce；
2, the effect of semaphore be notice institute either with or without seize third party lock association's journey, informing data be stored in it is slow
It deposits.Difference with semaphore concept in concurrency programming is that semaphore here is mainly an informing mechanism, and there is no strive
It robs；
3, all there is expired time in third party's lock, spin lock and semaphore, third party's lock, spin lock expired time be for
Preventing lock from not discharging causes to assist journey seemingly-dead；The expired time of semaphore is determined according to business, when duration≤service buffer fails
Between；
This programme makes caching a possibility that penetrating almost 0, and direct effect is that the hit rate of caching is got higher, while greatly
Limit ensure that original performance.Deep layer effect is that the handling capacity of project directly rises.
