Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
FIG. 1 is a flow chart of a preferred embodiment of the timer-based task execution method of the present invention. The order of the steps in the flowchart may be changed and some steps may be omitted according to various needs.
The timer-based task execution method is applied to one or more computer devices, wherein the computer device is a device capable of automatically performing numerical calculation and/or information processing according to preset or stored instructions, and the hardware comprises, but is not limited to, a microprocessor, an application specific integrated circuit (Application Specific Integrated Circuit, ASIC), a programmable gate array (Field-Programmable Gate Array, FPGA), a digital processor (Digital Signal Processor, DSP), an embedded device and the like.

The artificial intelligence software technology mainly comprises a computer vision technology, a robot technology, a biological recognition technology, a voice processing technology, a natural language processing technology, machine learning/deep learning and other directions.

S10, the message sending end synchronously sends the message to each receiving node in the distributed master and slave high-availability message receiving end cluster.
The high availability cluster of the primary and the standby refers to that the number of messages sent or received by all instance nodes in the cluster is completely consistent with the sequence of the messages.
In this embodiment, the message sending end may be a primary and standby high-availability message sending end cluster or a single-instance message sending end cluster.
For example: the message sending end can be a quotation sending end or a transaction message sending end and the like.
Accordingly, each receiving node in the distributed active and standby high-availability message receiving end cluster can be a quotation receiving end or a transaction message receiving end and the like.
In this embodiment, each receiving node in the distributed active-standby high-availability message receiving end cluster needs to ensure that the receiving nodes have the same input, and can simultaneously ensure that the receiving nodes have the same output data, that is, the task processing states of the receiving nodes need to be kept consistent, and the global message sequences received by all the receiving nodes are completely consistent, so that when the active receiving node is abnormal, any other standby receiving node can directly replace the abnormal active receiving node to execute the task.
S11, in the process of sending the message by the message sending end, the clock driving source cluster continuously and synchronously sends the time slice message to each receiving node according to a preset sending interval.
The preset sending interval can be configured according to actual task requirements.
S12, each receiving node constructs a logic clock based on the preset sending interval and the time slice message.
In this embodiment, the constructing, by each receiving node, a logic clock based on the preset transmission interval and the time slice message includes:
each receiving node determines the issuing sequence of each time slice message and takes the issuing sequence as the message sequence number of each time slice message;
each receiving node determines the number of the preset sending intervals between any two time slice messages according to the message sequence number of each time slice message;
each receiving node constructs the logic clock according to the product of the number of the preset sending intervals and the preset sending intervals between any two time slice messages.
For example: assume that the message received by each receiving node in the distributed primary and standby high availability message receiving end cluster is as follows:
wherein: snm represents a message issued by the message sending end, namely, a service message received by each receiving node, wherein n represents a sequence number identifier (namely, one message sending end or a plurality of message sending ends can be provided) of the message sending end, and m represents an mth message sent by the corresponding message sending end; tm represents each time slice message, where m represents an mth time slice message sent by the clock driving source cluster, i.e. a message sequence number of each time slice message. If the preset transmission interval is i, the time slice message t1 and the time slice message tm are separated by m i, and the logic clock running time may be set to i×m.
As long as the logic clocks are consistent, the timer triggering rules are also completely consistent, so that the system consistency requirement of the active and standby high-availability clusters is ensured.
S13, each receiving node executes corresponding tasks according to the logic clock and the message sent by the message sending end.
In this embodiment, the executing, by each receiving node, a corresponding task according to the logic clock and the message sent by the message sending end includes:
when the corresponding task is a timeout task, each receiving node determines the logic clock as a timer timeout calculation reference;
and each receiving node executes the overtime task according to the overtime calculation reference of the timer and the message sent by the message sending end.
It can be appreciated that some distributed active-standby high availability clusters require a timeout mechanism of a timer under certain scenarios to ensure that services run at regular time, but system clocks and processing speeds of multiple instances in the cluster cannot be guaranteed to be completely aligned, and even if deployed on the same machine, processing speeds between different processes are also different due to scheduling and competing resources. However, the master-slave high-availability clusters need to ensure that the same input is required to generate the same output, the system time is taken as a timeout judgment basis, and the timeout judgment among a plurality of examples cannot be guaranteed to be completely coincident, so that uncertainty influence is generated on the system output, different message output sequences can be generated when the same message input sequences are received among different example nodes of the distributed master-slave high-availability message receiving end clusters, and the design requirement of the consistency of the master-slave high-availability clusters cannot be met.
In view of the above problems, the present embodiment introduces the clock driving source cluster, although the processing speed of each receiving node is not completely consistent, since the sequence of messages received by each receiving node is completely the same, it can be inferred that the logic clock calculated by each receiving node is also completely the same, so tasks such as timeout processing of a timer can be implemented according to the logic clock, so as to ensure that the number of service messages processed by each receiving node is completely the same at a timeout point. In this way, for each receiving node in the distributed active-standby high-availability message receiving end cluster, under the condition that message input is completely the same, the number of received messages and the sequence of the messages can be ensured to be completely the same, namely, the consistency of timer clock execution among the distributed active-standby high-availability cluster nodes is ensured.
The embodiment can effectively ensure the system consistency under the scene of relying on a timer clock to realize the function and ensuring the consistency of the distributed active-standby high-availability clusters.
In the above embodiment, the problem of inconsistent message processing results of the distributed main and standby high-availability message receiving end clusters can be solved only by introducing the clock driving source clusters, the coupling of the whole system is smaller, and the original system can be integrated and applied quickly by slightly modifying.
In this embodiment, the method further includes:
in the process of transmitting the message by the message transmitting end, each receiving node receives the counting message transmitted by the counter cluster;
and each receiving node executes a counting task according to the counting message and the message issued by the message transmitting end.
With the above-described embodiments, in addition to the coincidence clock, coincidence counting is introduced to perform the relevant counting task.
According to the technical scheme, in the process that the message sending end synchronously sends the messages to each receiving node in the distributed main and standby high-availability message receiving end cluster, the clock driving source cluster continuously synchronously sends the time slice messages to each receiving node according to the preset sending interval, each receiving node builds a logic clock based on the preset sending interval and the time slice messages, and executes corresponding tasks according to the logic clock and the messages sent by the message sending end, and the clock driving source cluster is introduced as a timer, so that the distributed main and standby high-availability clusters can keep consistency when executing the tasks.
