Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
The embodiment of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can also basis
The accompanying drawing of offer obtains other accompanying drawings.
Fig. 1 is group system caching query method flow diagram provided in an embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
The present invention provides a kind of group system caching query method, as shown in figure 1, comprising the following steps：
S101, the average response time for determining each interface in timed task；
If S102, the average response time that interface be present are more than setting time threshold value, in timed task first time poll
During to interface, the current request state of saving interface；
S103, when timed task is polled to interface for the second time, if interface does not receive the returned data of bottom order, take
Disappear this requesting query.
In above-mentioned group system caching query method provided in an embodiment of the present invention, it is first determined each in timed task
The average response time of interface；If the average response time that interface be present is more than setting time threshold value, in timed task first
It is secondary when being polled to interface, the current request state of saving interface；When timed task is polled to interface for the second time, if interface is not received
To the returned data of bottom order, then cancel this requesting query.Using above-mentioned caching query method, use can be further reduced
The family stand-by period, Consumer's Experience is lifted, can fundamentally avoid interface time-out in traditional buffering scheme, cause bottom order
The problem of ceaselessly waiting is blocked, improves the stability and reliability of distributed cluster system, improves the competitiveness of storage product.
Further, in the specific implementation, in above-mentioned group system caching query method provided in an embodiment of the present invention,
The average response time of each interface in timed task is determined using following manner：
First, the response time of total interface in timed task is counted；
Then it is sampled, extrapolates the average response time of each interface automatically.
Further, in the specific implementation, in above-mentioned group system caching query method provided in an embodiment of the present invention,
If the average response time that step S102 has interface is more than setting time threshold value, interface is polled to for the first time in timed task
When, the current request state of saving interface, specifically it may comprise steps of：
First, it is easy overtime interface by interface flag if the average response time that interface be present is more than setting time threshold value；
Then, in timed task first time poll easily overtime interface, the execution state of automatic record easily overtime interface；
If first time end of polling(EOP), easy overtime interface does not receive the returned data of bottom order yet, will preserve easy time-out and connects
Mouth is to be carrying out state.
So by the keeping records interface polls state that time-consuming, these interfaces that time-consuming are polled to every time (i.e. easily
Overtime interface), judge that last time inquires about state, if there is no returning result also, just terminate this poll, avoid in bottom order
Can not be in the case of returned data, service end still sends inquiry request, accelerates the problem of order line process enters stuck state,
Improve the stability of product.
In the specific implementation, in above-mentioned group system caching query method provided in an embodiment of the present invention, it is determined that fixed
When task in each interface average response time while, can also comprise the following steps：
According to average response time, the timing request frequency of each interface of automated setting；
According to timing request frequency, each interface is polled.
So by calculating the average response time of interface automatically, intelligence formulates each interface timing request frequency, greatly
Improve Consumer's Experience.
Based on same inventive concept, the embodiment of the present invention additionally provides a kind of group system caching query equipment, due to this
The principle that equipment solves problem is similar to a kind of foregoing group system caching query method, therefore the implementation of the equipment may refer to
The implementation of group system caching query method, repeat part and repeat no more.
In the specific implementation, group system caching query equipment provided in an embodiment of the present invention, is specifically included：
Response time determining module, for determining the average response time of each interface in timed task；
Solicited status preserving module, if being more than setting time threshold value for the average response time of interface be present, fixed
When task for the first time when being polled to interface, the current request state of saving interface；
Requesting query cancels module, for when timed task is polled to interface for the second time, if interface does not receive bottom life
The returned data of order, then cancel this requesting query.
In above-mentioned group system caching query equipment provided in an embodiment of the present invention, it can be connect by what is extrapolated automatically
Average time of mouthful response, and by the keeping records interface polls state that time-consuming, it is polled to these every time time-consuming
Interface, judge that last time inquires about state, if there is no returning result also, just terminate this poll, it is slow fundamentally to avoid tradition
Interface time-out in scheme is deposited, causes bottom order to block the problem of ceaselessly waiting, improves the stability of distributed cluster system
And reliability, improve the competitiveness for storing product.
