Specific implementation mode
The core of the application is to provide a kind of distributed storage cluster and its service response control method, device, equipment
And computer readable storage medium, to effectively improve the balancing performance between each memory node.
In order to which technical solutions in the embodiments of the present application is more clearly and completely described, below in conjunction with this Shen
Attached drawing that please be in embodiment, technical solutions in the embodiments of the present application are introduced.Obviously, described embodiment is only
Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art
The every other embodiment obtained without making creative work, shall fall in the protection scope of this application.
Referring to FIG. 1, Fig. 1 is a kind of stream of the service response control method of distributed storage cluster provided herein
Cheng Tu, the service response controller being applied in distributed storage cluster, mainly includes the following steps that：
Step 1：Receive the service request that client is sent.
Specifically, service response control method provided herein is specifically and applies on service response controller.
Service response controller provided herein is deployed in distributed storage cluster, and with it is each in distributed storage cluster
Being established between memory node has communication connection relationship, can be managed to activities such as communication, the O&Ms of each memory node, be client
Communication bridge between end and each memory node.
Step 2：It is determined as the performance best storage node at current time to provide answering for this service response to client
Answer node；Performance best storage node be distributed storage cluster each memory node in load minimum memory node.
Specifically, in service response control method provided herein, when service response controller is received from visitor
After the service request at family end, can determine performance best storage node to carry out response, rather than as in the prior art that
Sample all carries out response by preset primary storage node always.Response node selected every time is all distributed storage in the application
Minimum performance best storage node is loaded in each memory node of cluster, so as to be effectively prevented from distributed storage cluster
Load imbalance the case where, safeguards system stable operation.
It is easily understood that performance best storage node is joined with time correlation, different moments, corresponding performance was best
Memory node is likely to be different.So can just be reaffirmed after often receiving a service request current
The performance best storage node at moment, to obtain performance best storage node the most accurate.Certainly, so to a certain extent
The speed of service response is influenced whether, and hence it is also possible to periodically just update the performance best storage node at current time, example
Such as, it was just updated once at interval of 5 minutes, in this way, when receiving service request, the last update result can be directly invoked
Performance best storage node as current time.Those skilled in the art can voluntarily select according to actual conditions and reality is arranged
Existing, the application is not limited thereto.
Step 3：Service request is forwarded to response node, and establishes the session connection between response node and client,
To provide service response to client by being deployed in the management software on response node from response node.
Specifically, after response node is determined, the session connection between response node and client can be established, by
Response node carries out service response.Usually, it can be all deployed with dedicated management software on each memory node and in client,
After session connection is established, response node can be interacted with user, provide service response.
As it can be seen that in the service response control method of distributed storage cluster provided herein, by the way that distribution is deposited
Minimum memory node is loaded in accumulation as the response node for providing service response to client, can effectively avoid appearance
The heavier situation of other memory node load effectively increases load and performance between entire each memory node of distributed storage cluster
It is harmonious.
The service response control method of distributed storage cluster provided herein, on the basis of the above embodiments：
As a kind of preferred embodiment, the determination step of performance best storage node includes：
Obtain all kinds of running performance index of each memory node；
The integrated operation performance indicator of each memory node is calculated by weighting method；
The best memory node of integrated operation performance indicator is determined as performance best storage node.
Specifically, when updating performance best storage node every time, weighting method can be used, each storage to getting
All kinds of running performance index of node are calculated, and obtain integrated operation performance indicator, and last foundation integrated operation performance refers to
Mark determines performance best storage node.Can voluntarily it be arranged by those skilled in the art as the concrete numerical value of weighting weight and real
It is existing.
Wherein, as a kind of preferred embodiment, all kinds of running performance index include following arbitrary combination：It is CPU usage, interior
Deposit occupancy, I/O bandwidth.Certainly, those skilled in the art can also select other running performance index, the application to this not
It is defined.
Further include after service request is forwarded to response node as a kind of preferred embodiment：
If response node failure, the performance best storage node at current time is redefined, and will be updated current
The performance best storage node at moment is determined as providing the response node of this service response to client.
It specifically,, then can be again when the response node catastrophic failure that script determines in order to ensure the continuity of service
The performance best storage node that current time is redefined out from normally functioning memory node, as updated response section
It puts to continue to provide service response to client.
As a kind of preferred embodiment, the management software in each memory node is given tacit consent to standby.
Specifically, as described above, the former response node that other memory nodes can be ready to take over failure is taken
Business response, and in order to enable the process of taking over be completed with faster speed, the management software in each memory node can be enabled normal
In the case of all give tacit consent to standby, i.e., non-closed state.As a result, once needing to carry out the switching of response node, shape of awaiting orders
The management software of state will start running at once so that by the handoff procedure of former response node to updated response node in user
It is just quickly completed when not yet discovering, improves service response efficiency and user experience.
As a kind of preferred embodiment, each memory node shares the distributed type assemblies cache module of distributed storage cluster
Carry out data buffer storage.
Specifically, in order to ensure the data cached consistency of each memory node, mould is cached using distributed type assemblies
Block carries out data buffer storage to each memory node, that is, each memory node shares a data.Skill is cached for distributed type assemblies
Art passes through the means such as data check, other memory node institutes after a memory node is modified the data of caching
The data read are also the data after being modified.Compared to traditional each memory node, caching respectively counts alone respectively
According to scheme, using distributed type assemblies caching scheme can the data cached accuracy of each memory node of effective guarantee, work as progress
After the update of response node, updated response node can directly transfer data cached offer service, without as traditional scheme
In the data of updated response node are updated again like that.
The service response control device of distributed storage cluster provided herein is introduced below.
Referring to Fig. 2, Fig. 2 is a kind of knot of the service response control device of distributed storage cluster provided herein
