Description

Distributed system, method and electronic equipment for distributing configuration information in real time
Technical Field
The present application relates to the field of computer network technology, and more particularly, to a distributed system, method and electronic device for distributing configuration information in real time.
Background
The distributed system generally comprises a client, a control node and a service node, wherein the client obtains service node information through the control node and is connected with the service node to obtain service. In a distributed system, a certain configuration information needs to be shared between a client and a service node to enable the service node to normally serve the client. Therefore, once the configuration of the client is changed (or it is understood that the configuration information is changed), the service node needs to acquire new configuration information to ensure that the changed configuration is quickly effective, so that the client is correctly served.
At present, there are two methods for a service node in a distributed system to obtain new configuration information. The first method is to query configuration information from a service node to a control node at regular time, and the timeliness of the method is determined by the polling period, the timeliness is poor if the polling period is long, and the timeliness is good if the polling period is short, but the too short polling period can cause the system communication load to be obviously increased and can bring unnecessary system burden when no configuration update is carried out. The second method is that a configuration center node is added in the distributed system, and the configuration center node is relied to distribute configuration information to the service node, in this way, two hops are needed from the initiation of configuration change to the completion of configuration change, and two hops are also needed for a client to access the configuration information, so that the response time of the distributed system to configuration update is prolonged, and the unreliability of the distributed system is increased. And a communication channel from the configuration center node to the service node needs to be established, and because the communication channels simultaneously established in the distributed system are limited, the establishment of the communication channel between the configuration center node and the service node alone will limit the scale of the distributed system.
Therefore, a distributed system for distributing configuration information in real time is required to overcome the above technical problems.

Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
FIG. 1 is a schematic diagram of a distributed system according to one embodiment of the present application. The application scenario shown in fig. 1 includes a client, a control node and a service node, where the control node includes a control management module and a configuration management module, the configuration management module includes a notification module, and the control management module and the configuration management module share a communication channel between the control node and the service node. The client obtains the information of the service node through the control node and is connected with the service node to obtain service. Typically, the client and the service node share certain configuration information so that the service node serves the client normally. Therefore, when the configuration of the client is changed, the awareness of the client, the service node and the control node in the distributed system that needs to be changed is consistent, or the client and the service node need to acquire new configuration information, so as to ensure that the changed configuration is quickly effective.
Optionally, in some embodiments, a control management module in the distributed system in fig. 1 receives a configuration change request message sent by a client, where the configuration change request message carries a configuration change requirement of a user; the control management module determines a target service node corresponding to the configuration changed by the user in the service nodes based on the configuration change requirement, and generates target configuration information corresponding to the configuration changed by the user; the control management module calls the configuration management module, and sends a configuration change notification message to the target service node through a notification module in the configuration management module, wherein the configuration change notification message comprises target configuration information; the control management module calls the configuration management module, and sends a configuration change request response message to the client through a notification module in the configuration management module, wherein the configuration change request response message comprises target configuration information.
For example, when a user needs to change the size of the cloud disk, for example, the size of the cloud disk is changed from 1T to 2T. The user sends a configuration change request message to the control node through the client, wherein the configuration change request message carries the configuration change requirement of the user (the size of the cloud disk is changed from 1T to 2T). Also taking the example that the user requests to update the cloud disk size as an example, the target configuration information may include information such as the cloud disk size, the block size (BlockSize), whether compression is supported, and the address of the service node corresponding to each Segment (Segment).
Further, taking the above example that the configuration change requirement is that the size of the cloud disk is changed from 1T to 2T, the control node determines that the corresponding target service nodes are the service node a and the service node B when the size of the cloud disk is 2T, and then the control node actively issues the target configuration information to the service node a and the service node B. Therefore, the distributed system of the embodiment of the application can actively send the target configuration information to the target service node corresponding to the configuration changed by the user after the target configuration information is generated according to the configuration changed by the user, and can avoid the service node from missing monitoring the configuration updated by the user.
Optionally, in some embodiments, the control management module in fig. 1 is further configured to persist the configuration change requirement as persistent data. Persisting the configuration change requirements may be understood as saving the configuration change requirements to a permanently savable storage device (e.g., disk). Therefore, even if the control node is broken down, the configuration change requirement of the user can be recovered from the storage device.
Optionally, as an embodiment, as shown in fig. 2, the configuration management module shown in fig. 1 further includes a retry management module: if the retry management module determines that the target service node fails to execute the processing operation related to the target configuration information, the retry management module sends the target configuration information to the target service node at a first preset time interval until the target service node successfully executes the processing operation related to the target configuration information or determines that the control management module receives a configuration change abandon request message sent by the client and used for requesting to abandon the configuration change.
That is, after receiving the target configuration information, the target service node needs to perform a processing operation related to the target configuration information, where the processing operation related to the target configuration information includes updating some memory states of itself. And then the target service node feeds back the processing result to the control node. If the retry management module in the configuration management module in the control node determines that the feedback processing of the service node fails, the retry management module will delay a period of time and then send the target configuration information to the target service node again. If the target service node fails to feed back the target configuration information again after sending the target configuration information to the target service node again, the retry management module will send the target configuration information to the target service node again. Or it may be understood that, if the target service node fails to perform the feedback processing after the notification module in the control node first sends the target configuration information to the target service node, the retry management module in the control node sends the target configuration information to the target service node according to the first preset time interval until the target service node succeeds in the feedback processing or the client abandons the update configuration actively. Therefore, the target service node can be ensured to successfully receive the target configuration information and successfully execute the processing operation related to the target configuration information, and further, the service is successfully provided for the client.
As an example, the reason for the failure of the target serving node processing is a network timeout or a down of the target serving node. The client actively abandoning the update configuration may be, for example, a cloud disk in the distributed system being deleted.
Further, in some embodiments, in order to ensure the consistency of the behavior perceived by the client and the service node for the configuration, the configuration change notification message further includes a target configuration sequence number corresponding to the target configuration information, and the configuration change response message further includes a target configuration sequence number, where the target configuration sequence number is used to characterize the version of the target configuration information. Or it can be understood that the configuration management module in the control node maintains a configuration serial number, the configuration serial number is only increased but not decreased, and each time the user requests configuration change, the configuration serial number is increased by 1. Therefore, the client can obtain the configuration serial number through the access control node, and the service node also obtains the configuration serial number when receiving the configuration change notification message.
Optionally, after the client obtains the configuration sequence number, when the client initiates access to the target service node, the client sends an access request message to the target service node, where the access request message is used to request data on the target service node, and the access request message includes the acquired configuration sequence number, and receives an access request response message sent by the target service node. Specifically, when the configuration serial number acquired by the client is greater than or equal to the target configuration serial number (the configuration serial number acquired by the target service node), the access request response message includes data requesting access, and when the configuration serial number acquired by the client is smaller than the target configuration serial number, the access response message includes access error information.
Specifically, in some embodiments, if the access request response message received by the client includes the access error information, it is indicated that the configuration sequence number acquired by the client is smaller than the configuration sequence number maintained by the target service node, that is, the configuration of the user is updated at the service node, but the client is not yet aware of the configuration, the client may initiate a query to the control node as needed, acquire the configuration information and the configuration sequence number corresponding to the updated configuration, and access the target service node again and obtain a service based on the configuration information and the configuration sequence number corresponding to the updated configuration. Therefore, the control management module in fig. 1 or fig. 2 is further configured to receive a configuration information query request message sent by the client, where the configuration information query request message is used to request to query the target configuration information; and sending a configuration information query request response message to the client, wherein the configuration information query request effect message comprises target configuration information and a target configuration sequence number.
Further, in order to increase the disaster tolerance and fault tolerance capability of the distributed system, as shown in fig. 3, the configuration management module shown in fig. 1 further includes a configuration checking module; the configuration checking module sends a configuration sequence number query request message to the target service node, wherein the configuration sequence number query request message is used for requesting the target service node to feed back the configuration sequence number acquired by the target service node; the configuration checking module receives a configuration serial number obtained by the target service node and fed back by the target service node; if the configuration management checking module judges that the target configuration serial number is larger than the configuration serial number acquired by the target service node, the notification module sends target configuration information to the target service node again; and if the configuration checking module judges that the target configuration serial number is equal to the configuration serial number acquired by the target service node, determining that the notification module successfully sends the target configuration information to the target service node.
In other words, the control node actively initiates a configuration sequence number query request to the target service node, checks the configuration sequence number acquired by the target service node, compares the configuration sequence number acquired by the target service node with the configuration sequence number of the control node, and executes corresponding processing based on the comparison result. For example, if the configuration sequence number of the control node itself is greater than the configuration sequence number acquired by the target service node, the control node starts a configuration issuing mechanism and issues the target configuration information to the target service node. And if the configuration serial number of the control node is consistent with the configuration serial number acquired by the target service node, determining that the target configuration information is successfully sent to the target service node, namely the control node does not process the target configuration information. Moreover, it can be understood that, because the persistence of the control node itself depends on the distributed consistency protocol to perform the persistent backup to 3 or more than 3 machines, and the configuration is issued after the persistence, the situation that the configuration sequence number of the control node itself is smaller than the configuration sequence number acquired by the target service node does not occur.
Specifically, in some embodiments, the configuration checking module in the control node may send the configuration sequence number query request message to the service node at a second preset time interval.
The distributed system according to the embodiment of the present application is described in detail above with reference to fig. 1 to 3, and a method for distributing configuration information in real time according to an embodiment of the present application will be described below with reference to fig. 4.

Fig. 5 illustrates a method of distributing configuration information in real-time according to another embodiment of the present application, the method illustrated in fig. 5 being performed by a client. It should be noted that the interaction process between the client and the control node and the service node described from the client side is the same as that described from the control node side, and is not described herein again to avoid repetition.

Fig. 6 illustrates a method for distributing configuration information in real time according to still another embodiment of the present application, where the method illustrated in fig. 6 is performed by a service node. It should be noted that the interaction process between the service node and the control node and the client described in the slave service node side is the same as that described in the slave control node side, and is not described herein again to avoid repetition.
As shown in fig. 6, at S602, a configuration change notification message sent by a control node is received, where the configuration change notification message includes target configuration information, and the target configuration information is generated by the control node based on a configuration change requirement of a user carried in a configuration change request message sent by a client.
Optionally, in some embodiments, when the service node receives the configuration change notification message, based on the target configuration information in the configuration change notification message, a processing operation related to the target configuration information is performed, for example, the service node updates some memory states of itself, and then feeds back a processing result to the control node, so that the control node sends the target configuration information to the service node at a first preset time interval when determining that the service node fails to perform the processing operation related to the target configuration information, until the service node successfully performs the processing operation related to the target configuration information or receives a configuration update abort request message sent by the client for requesting to abort the configuration change. Therefore, the service node can be ensured to successfully receive the target configuration information and successfully execute the processing operation related to the target configuration information, and further, the service is successfully provided for the client.
At S604, the client is served based on the configuration change notification message.
Optionally, as an embodiment, the configuration change notification message further includes a target configuration sequence number corresponding to the target configuration information, where the configuration sequence number is used to characterize a version of the target configuration information.

That is, if the configuration sequence number acquired by the client is equal to the configuration sequence number maintained by the service node, the service node may provide normal service for the client. If the configuration serial number acquired by the client is greater than the configuration serial number maintained by the service node, it indicates that the client initiates a request with the changed configuration, and the configuration information of the service node is not matched with the changed configuration. It can be understood that the situation that the configuration sequence number acquired by the client is greater than the configuration sequence number maintained by the service node rarely occurs, and only the configuration information retransmission interval may occur in the process of configuration delivery or due to some reason, and the waiting time of the client is also very short. If the configuration serial number acquired by the client is smaller than the configuration serial number maintained by the service node, it is indicated that the configuration of the user is updated at the service node, but the client is not yet aware of the configuration, in this case, the client may initiate query to the control node as required, acquire the configuration information and the configuration serial number corresponding to the updated configuration, and access the service node again and obtain service based on the configuration information and the configuration serial number corresponding to the updated configuration.
Optionally, as an embodiment, the method shown in fig. 6 further includes: receiving a configuration sequence number query request message sent by a control node, wherein the configuration sequence number query request message is used for requesting a service node to feed back a configuration sequence number acquired by the service node; and feeding back the acquired configuration serial number to the control node.
Optionally, as an embodiment, the receiving of the configuration sequence number query request message sent by the control node may specifically be: and receiving a configuration sequence number query request message sent by the control node at a second time interval.
