[0002] In the current big data era, distributed systems are widely used in fields such as the Internet, cloud computing, the Internet of Things, and artificial intelligence.

[0003] In distributed systems, unique number generation in a high-concurrency environment is a key issue. At present, common unique number generation schemes include generation strategies based on UUID (Universally Unique Identifier). However, this method has certain shortcomings: UUID usually includes 36 bytes, which is a huge burden for storage and transmission, especially in systems that need to generate numbers frequently. UUID is randomly generated and has no fixed order, which is disadvantageous for some scenarios that need to be processed in the order of numbers. At the same time, although it is relatively fast, in high-concurrency scenarios, if each request needs to generate a UUID, it will still affect performance. Therefore, there is an urgent need for a new unique number generation method in high-concurrency scenarios. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0056] Embodiment 1

[0057] Figure 1 A flowchart of a unique number generation method is provided for an embodiment of the present invention. This embodiment is applicable to the generation of unique numbers in multiple concurrent scenarios. The method can be executed by a unique number generation device. The unique number generation device can be implemented in the form of hardware and / or software. The unique number generation device can be configured in an electronic device.

[0058] like Figure 1 As shown, the unique number generation method includes:

[0059] S101: After the number generation device is started, access a pre-deployed distributed coordination service cluster, and obtain an initial machine identifier corresponding to the number generation device from the distributed coordination service cluster.

[0060] In an embodiment of the present invention, a number generation device may be a node in a distributed business system in which a number generation algorithm is deployed, and the number generation algorithm may be, for example, a snowflake algorithm or other self-incrementing unique identifier generation algorithm. Exemplarily, the number generation algorithm adopts a snowflake algorithm, and then a number generation device may be regarded as a snowflake node. A pre-deployed distributed coordination service distributed coordination service cluster includes a master node and multiple standby nodes, which are distributed on different physical machines or virtual machines, wherein the master node provides services to the outside, and the standby node is used to synchronize data from the master node. A namespace is specially created for the number generation algorithm in the host point of the distributed coordination service cluster. Thus, in the initial configuration phase, an initial machine identifier (for example, composed of a data center ID and a machine ID) is assigned to each number generation device, and the mapping relationship between each number generation device and the initial machine identifier is saved in the preset namespace of the distributed coordination service cluster. It can be understood that by creating a special namespace, data and nodes related to the number generation algorithm can be isolated from data of other services or functions to avoid data confusion and mutual interference between different services.

[0061] In an embodiment of the present invention, when the number generation device is started, it can establish a connection with a pre-deployed distributed coordination service cluster and access the distributed coordination service cluster to obtain an initial machine identifier corresponding to the number generation device from the namespace of the distributed coordination service cluster, so that a unique number can be subsequently constructed based on the initial machine identifier.

[0062] S102: In response to receiving a number generation request in a high-concurrency environment, determine a timestamp and a sequence number corresponding to each number generation request.

[0063] In the embodiment of the present invention, a high concurrency environment refers to a situation where a large number of requests arrive at the system for processing at the same time. For example, during the promotion of an e-commerce platform, a large number of users place orders and pay for goods at the same time. At this time, it is necessary to send a number generation request to the number generation device to request the number generation device to generate a unique number (such as a payment serial number) for a large number of payment orders generated at the same time. In order to generate a corresponding unique number for each number generation request, the number generation device determines the timestamp and serial number corresponding to each number generation request after receiving the number generation request (the number is multiple) in a high concurrency environment; specifically, for any number generation request in a high concurrency environment, the current time information is obtained, and the current time information is converted into the timestamp corresponding to the number generation request. The serial numbers corresponding to the number generation requests are determined by the self-increment of the serial number. It can be understood that in a high concurrency environment, a number generation device may receive multiple number generation requests in the same millisecond. By the self-increment of the serial number, the serial number corresponding to each number generation request is determined, which can ensure that the serial number of each number generation request is different. In this way, even if the timestamps corresponding to two or more number generation requests are the same, they can be distinguished by the different corresponding serial numbers.

[0064] S103. Based on the snowflake algorithm, a corresponding unique number is generated for each number generation request according to the initial machine identifier, the timestamp and the serial number corresponding to each number generation request.

[0065] In the embodiment of the present invention, the unique number generated by the snowflake algorithm is usually a 64-bit long integer. To generate a corresponding unique number for a number generation request, it is first necessary to determine the target positions of the initial machine identifier, timestamp and serial number corresponding to the number generation request in the 64-bit number; and then, according to the target positions, assemble the initial machine identifier, timestamp and serial number corresponding to the number generation request into the unique number corresponding to the number generation request.

[0066] In an embodiment of the present invention, the snowflake algorithm and the distributed coordination service cluster are combined to generate a unique number. Compared with the UUID-based generation strategy, the generated unique number is shorter and occupies less transmission and storage resources; and the unique number corresponding to each number generation request can be sorted by serial number, which is more suitable for a high concurrency environment.

[0067] Embodiment 2

[0068] Figure 2 A flowchart of a method for generating a unique number is provided for an embodiment of the present invention. Figure 2 , the method comprises the following steps:

[0069] S201. After the number generation device is started, a distributed lock provided by the distributed coordination service cluster is obtained; and after the distributed lock is successfully obtained, an initial machine identifier corresponding to the number generation device is read from a node storing machine identifiers in the distributed coordination service cluster.

[0070] In an embodiment of the present invention, after starting, the number generation device will establish a connection with the distributed coordination service cluster. Since there are multiple number generation devices, if multiple number generation devices simultaneously access the node storing the machine identification in the distributed coordination service cluster to read the initial machine identification corresponding to the number generation device, an identification conflict will occur. For example, after two number generation devices read the same initial machine identification, the numbers generated based on this initial machine identification may be repeated, destroying the uniqueness of the number. In order to avoid this problem, the present invention introduces a distributed lock mechanism. Specifically, when multiple number generation devices simultaneously request to read the initial machine identification corresponding to the number generation device, a distributed lock is first obtained. When a number generation device successfully obtains the lock, the machine identification is read, and then it can use this identification to generate numbers according to a predetermined rule. Other number generation devices need to wait for the lock to be released before they can obtain the initial machine identification. In this way, through the distributed lock, each number generation device can access the node storing the machine identification in the order of obtaining the lock, so that the orderliness of the operation between devices is realized, and there will be no confusion or inconsistency of identification caused by concurrent access.

[0071] S202: In response to receiving a number generation request in a high-concurrency environment, determine a timestamp and a sequence number corresponding to each number generation request.

[0072] Optionally, in response to receiving a number generation request in a high concurrency environment, current time information is obtained and converted into a timestamp corresponding to the number generation request; and serial numbers corresponding to each number generation request are determined by self-incrementing the serial numbers.

[0073] S203. Based on the snowflake algorithm, a corresponding unique number is generated for each number generation request according to the initial machine identifier, the timestamp and the serial number corresponding to each number generation request.

[0074] In the embodiment of the present invention, the unique number generated by the snowflake algorithm is usually a 64-bit long integer. To generate a corresponding unique number for a number generation request, it is first necessary to determine the target positions of the initial machine identifier, timestamp and serial number corresponding to the number generation request in the 64-bit number; and then, according to the target positions, assemble the initial machine identifier, timestamp and serial number corresponding to the number generation request into the unique number corresponding to the number generation request.

[0075] In an embodiment of the present invention, when the numbering device obtains the corresponding initial machine identifier from the distributed coordination service cluster, a distributed lock mechanism is introduced. Through the distributed lock, each numbering device can access the node storing the machine identifier in the order of acquiring the lock, thereby achieving orderliness of operations between devices.

[0076] Embodiment 3

[0077] Figure 3 The present invention provides a flowchart of a unique number generation method. Figure 3 , the method comprises the following steps:

[0078] S301: After the number generation device is started, access a pre-deployed distributed coordination service cluster, and obtain an initial machine identifier corresponding to the number generation device from the distributed coordination service cluster.

[0079] Optionally, after the number generation device is started, a distributed lock provided by the distributed coordination service cluster is obtained; and after successfully obtaining the distributed lock, an initial machine identifier corresponding to the number generation device is read from a node storing machine identifiers in the distributed coordination service cluster.

[0080] In an embodiment of the present invention, the distributed coordination service cluster monitors the status of the number generation device in real time through a monitoring mechanism, and releases the initial machine identifier corresponding to the number generation device after determining that the number generation device is offline (for example, the number generation device is offline due to a fault), so that during the period when the number generation device is offline, if a new number generation device requests the initial machine identifier, the released initial machine identifier can be assigned to the new number generation device; wherein, the new number generation device can be newly expanded to cope with high concurrency scenarios. In this way, it can be avoided that a machine identifier is occupied invalidly for a long time, resulting in a waste of the machine identifier. After the offline number generation device is back online, the distributed coordination service cluster is re-accessed to obtain the latest machine identifier, for example, the currently idle machine identifier is read from the distributed coordination service cluster, that is, the distributed coordination service cluster assigns the currently idle machine identifier to the number generation device that is back online.

[0081] S302: In response to receiving a number generation request in a high-concurrency environment, determine a timestamp and a sequence number corresponding to each number generation request.

[0082] Optionally, in response to receiving a number generation request in a high concurrency environment, current time information is obtained and converted into a timestamp corresponding to the number generation request; and serial numbers corresponding to each number generation request are determined by self-incrementing the serial numbers.

[0083] S303. Based on the snowflake algorithm, a corresponding unique number is generated for each number generation request according to the initial machine identifier, the timestamp and the serial number corresponding to each number generation request.

[0084] S304. Monitor the operating status of the distributed coordination service cluster in real time through a monitoring mechanism.

[0085] S305: If it is determined according to the running status that the master node of the distributed coordination service cluster fails, the cluster fault tolerance mechanism is triggered to perform node recovery.

[0086] In an embodiment of the present invention, the distributed coordination service cluster has high availability and fault tolerance. On this basis, the operating status of the distributed coordination service cluster is monitored in real time through a monitoring mechanism. If the main node of the distributed coordination service cluster is determined to be faulty according to the operating status, the cluster fault tolerance mechanism is triggered to perform node recovery to ensure that the distributed coordination service cluster provides services to the outside normally. Exemplarily, if the main node in the distributed coordination service cluster fails, the cluster fault tolerance mechanism can be used to select one of the multiple backup nodes of the distributed coordination service cluster as the main node to continue to provide services to the outside. That is, when a node in the distributed coordination service cluster fails, it can be repaired through the fault tolerance mechanism to ensure the continuity of services provided by the distributed coordination service cluster.

[0087] In the embodiment of the present invention, it can be ensured that the cluster can still work normally when a node fails, thereby ensuring the continuity of service.
