Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In view of the foregoing, a first aspect of the embodiments of the present invention provides an embodiment of an active push method for a distributed system. Fig. 1 is a schematic diagram illustrating an embodiment of a method for active push of a distributed system provided by the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:
s1, acquiring monitoring data to judge whether a message event exists;
s2, responding to the existence message event, notifying the client and receiving the request of the client;
s3, establishing corresponding threads according to the number of the requests of the client, and taking out a corresponding client message queue from the global service queue by each thread;
s4, resolving a corresponding message event from the client message queue according to the request of the client, and sending an event response request to the cluster; and
and S5, responding to the response returned by the cluster, and sending the message event to the client.
When the client and the server interact for the first time, authentication (TOKEN authentication or user management system) needs to be carried out on the client, authentication verification is carried out after the identity authentication information of the client is received, and if the authentication is successful, the request data receiving and sending thread is waited for further processing; the request data receiving and sending thread polls all client requests which are authenticated by the request processing thread, packs the received client requests into a message structure (such as a common Json object) and then sends the message data to a client message queue (ismClientQueue) corresponding to the client, and then adds the message queue to the tail of a global service queue (globalserviceQueue) and waits for further processing; if the message data is received, the message data is directly decoded and then forwarded to the client. The connection request mode and the identity authentication mode can be adapted to the current mainstream mode, and the invention does not make specific requirements.
Specifically, the following process may be adopted:
and judging whether the connection of the client is received or not, if so, going to the next step, and if not, continuing to wait for receiving the message connection request from the client. A client request processing thread is newly built and started and marked as A; and newly building and starting a request data transceiving thread, and marking as B. The temporary process data tmpArrA of a is initialized. The thread A monitors the client request, and the thread B polls the processing result array tmpArr of the thread A. The client requests the processing thread to authenticate and request the identity of the client, and if the authentication is successful, the client is put into tmpArr. The thread B acquires tmpArr data, if len (tmpArr) is larger than 0, the tmpArr data is packed into a message structure body, and then the tmp data is sent to an ismClientQueue queue; if tmpArr is empty, polling continues. And the thread B acquires the returned response data and sends the data to the corresponding client according to the client identifier.
The cluster includes two nested layers of message queues: a global service queue (globalServiceQueue) and a client message queue (ismClientQueue) to which the client has established a connection. The global service queue is a common global message circular queue (which can be implemented by using a common array), and is mainly responsible for maintaining and scheduling the client message queue (that is, different client message queues exist in the global service queue); the client message queue maintains different requests of the client, collects and monitors data in the storage cluster, and encapsulates data events into an ismDataItem form and puts the data events into the client message queue (namely, the client message queue has different requested ismDataItem message events) if the cluster data change is monitored and the changes need to be informed to the client (such as hardware equipment part failure in the cluster, storage pool/logical volume data update and other important operations and other monitorable items). The global service queue manages the client request queues as if there are multiple concurrent producers and concurrent consumers, so that locking is required for access operations such as message enqueuing or dequeuing. The global service queue directly allocates a default queue space (for example, 1000) to the queue during initialization, and automatically expands the capacity of the queue when the queue is full, generally expanding the capacity of the allocated space by twice.
Each element in the global service queue is a reference of a client message queue, a space is allocated by default and a plurality of empty client service queues are mounted during initialization, and when different clients send different requests, corresponding request message events are filled into the ismClientQueue. When the module is started, a plurality of working threads (6 working threads are configured by default, the number of the threads can be modified, and generally is not more than 128), when the working threads start working, a global service queue is locked, then a client message queue is continuously taken out from the global service queue, then a message event (ismDataItem) is taken out from the client message queue, and a corresponding cluster service is called (generally, a callback operation is performed, for example, a disk state alarm or a storage pool creation operation event is obtained from an alarm service of a cluster); after the message event is acquired, the message is decoded and packaged into message data with a corresponding format, the message data is directly sent to the client request monitoring module, and the request data is processed by a request data receiving and sending thread in the client request monitoring module and returned to the client. Namely: the request data response operation does not pass through a message queue, and the data result is directly forwarded to the client request monitoring module for processing.
Monitoring data is acquired to determine whether a message event exists. Data changes or device state changes belong to message events, so if there are data changes or device state changes in the cluster, it can be regarded as a message event.
In response to the presence message event, a request is sent to the client to notify the client and receive the client's request. If the cluster has the message event, the server side sends a request to the client side to inform the client side that the request can be sent, and at the moment, the client side sends a corresponding request according to the requirement.
In some embodiments, establishing the corresponding threads according to the number of requests of the client, wherein each thread fetching the corresponding client message queue from the global service queue further comprises: and locking a corresponding client message queue, and performing format conversion on the message event to write the message event into the client message queue.
In some embodiments, the method further comprises: and responding to a new message event written in the client message queue, and writing the client message queue into the tail of the global service queue.
And establishing corresponding threads according to the number of the requests of the client, and taking out a corresponding client message queue from the global service queue by each thread. After receiving the requests sent by the client, the server establishes a corresponding number of threads according to the number of the requests sent by the client, for example, one thread is established by one request, or two threads are established by one request, or one thread is established by two requests. After the thread starts, the global service queue is locked. Each thread determines a corresponding client according to the source of the request, determines a client message queue based on the client, and then takes the client message queue out of the global service queue.
And analyzing a corresponding message event from the client message queue according to the request of the client, and sending an event response request to the cluster. The thread analyzes the request of the client, then determines the message event needed by the request, and then analyzes the corresponding message event from the message queue of the client, if the message event needed by the client exists in the message queue of the client, the thread calls the request service of the corresponding ismDataItem, and sends an event response request to the cluster.
And sending the message event to the client in response to receiving the response returned by the cluster. In some embodiments, said sending said message event to said client comprises: decoding the message event and format converting the decoded message event for sending to the client. And releases the global service queue.
The invention provides an active pushing method in a distributed storage system.A storage cluster actively pushes request data to a client in a client queue by collecting monitoring data of the storage cluster when data updating exists in a data queue. The invention can not only reduce the development task amount of the client, but also reduce the pressure on the server caused by polling the cluster data of the server by the client, and improve the real-time performance and the accuracy of cluster monitoring; meanwhile, for the development framework, the request and the service are flattened, and the cluster monitoring logic sinks to the service end, so that the integrity and the usability of the whole development framework are facilitated.
