Description

Technical Field

[0001] The present disclosure generally relates to the field of computer technology, and in particular to a single point failure processing method, apparatus, computer equipment and storage medium. Background Art

[0002] The securities trading system implements the FIX protocol through the Financial Information Exchange (FIX) service and uses the Transmission Control Protocol (TCP) to establish a long connection with the upstream channel provider. This long connection is called a FIX Session. Through this FIX Session, transaction information can be accurately exchanged.

[0003] Due to the special features of FIX Session, namely, FIX service can only be deployed on certain fixed machines, the same order must be changed and cancelled through the original FIX Session after it is placed, and if a FIX service is connected to a FIX Session, other FIX services cannot connect to the FIX Session until the existing connection is disconnected. These special features will make it impossible for FIX service to scale horizontally. In this case, once a FIX Session fails, it may cause the serious consequence of paralysis of securities trading of users in a certain category or partition.

[0004] At present, the relevant technologies establish a network dedicated line with master-slave switching capability between the FIX service and the upstream channel, automatically switch to the backup line when the main line fails, and automatically switch to the public network when both the main and backup lines fail; or configure a master and backup node for a single FIX service, the two nodes compete for the same distributed lock, when the master node goes down, the backup node automatically upgrades to the master node, and re-establishes the FIX Session. However, both methods are based on the fact that the FIX service of the remote upstream channel provider has not failed. Once the upstream fails, the FIX connection cannot be established normally, making the trading system unavailable. At the same time, the processing process is extensive, and it is difficult to achieve elegant recovery after the failure. Summary of the invention

[0045] In order to enable those skilled in the art to better understand the disclosed solution, the technical solution in the disclosed embodiment will be clearly and completely described below in conjunction with the drawings in the disclosed embodiment. Obviously, the described embodiment is only a part of the disclosed embodiment, not all of the embodiments. Based on the embodiments in the disclosed embodiment, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the disclosed embodiment.

[0046] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described can be implemented in sequences other than those illustrated or described herein.

[0047] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules not explicitly listed or inherent to these processes, methods, products, or apparatuses.

[0048] The technical terms involved in the embodiments of the present disclosure are as follows:

[0049] FIX Protocol: An open protocol provided by the International FIX Association to promote the process of electronic international trade and establish a real-time electronic communication protocol between various participants (including investment managers, brokers, buyers and sellers, etc.).

[0050] Service registration: registers the module information that provides a service (usually the IP and port of the service) to a common component (such as zookeeper or consul).

[0051] Service discovery: means that newly registered service modules can be discovered by other callers in a timely manner, and automatic discovery can be achieved regardless of whether a service is added or deleted.

[0052] Single Point of Failure: When a single point failure occurs in a computer system or network, it will affect the entire system or network, causing the entire system or network to be paralyzed.

[0053] For ease of understanding and explanation, the following Figures 1 to 12 The single point failure handling method, apparatus, computer equipment and storage medium provided by the embodiments of the present disclosure are described in detail.

[0054] Please refer to Figure 1 , which is a basic flow chart of a single point failure handling method provided by an embodiment of the present disclosure. The method comprises the following steps:

[0055] S101, in response to a received order request, determining the type of the order request.

[0056] For example, the types of order requests in the embodiments of the present disclosure may include, but are not limited to, new orders, order changes, and order cancellations. Among them, new orders refer to newly placed orders, that is, there is no historical record; order changes refer to modifying the original order, and order cancellations refer to canceling the original order. It can be understood that there are historical records for these two situations. The advantage of such a setting is that the securities trading system in the embodiments of the present disclosure can process different order requests, thereby meeting diverse usage requirements and expanding the scope of application.

[0057] S102, according to the dynamic routing table and the type of the order request, selecting a FIX service node in the dynamic routing table whose status bit is available for business processing, wherein the status bit of the faulty FIX service node is disabled.

[0058] Exemplarily, as shown in Table 1, the dynamic routing table in the embodiment of the present disclosure includes description information of the FIX service node. For example, the description information may include but is not limited to the FIX service node name (name), the FIX Session status (session_status), the access endpoint parameter (end_point), the access protocol parameter (access_protocol) and the weight value of the FIX Session (session_priority), etc.

[0059] Table 1 Dynamic routing table example

[0060]

[0061] It should be noted that when the FIX Session status is available, it is represented by the number 1, and conversely when the FIXSession status is disabled, it is represented by the number 0. Further, in the process of a single point failure, the disclosed embodiment can shut down the FIX service node through the management interface, and actually call the control service to set the session_status status bit of the dynamic routing table to 0 to indicate the shutdown state. At the same time, this state change will also be notified to each business service, so that it can immediately update the local cache.

[0062] To better understand the single point failure processing method provided by the embodiment of the present disclosure, Figure 2 The overall architecture shown in FIG. 1 is described in detail. The overall architecture may include but is not limited to management interface, control service, business service and stateful single point service.

[0063] It should be noted that the business service queries the dynamic routing table when routing orders, that is, lazy loading, and caches it locally. Figure 3As shown, after the business service receives the order request, it first determines whether the dynamic routing table cache is in the local cache. If it does not exist, it queries the control service and caches the queried dynamic routing table locally. Furthermore, after the business service obtains the dynamic routing table, it first filters out the routes with session_status 0, and then processes them accordingly according to the types of different order requests, thereby improving efficiency.

[0064] Optionally, in some embodiments of the present disclosure, if the type of order request is a new order, node selection is performed based on the weight values ​​of the available FIX service nodes, such as using the FIX service node with the largest weight value. If the type of order request is to change or cancel an order, the routing identification code (identification, ID) corresponding to the order request when placing the order is obtained, and based on the routing identification code, the available FIX service nodes are determined, thereby implementing a sticky routing method. For example, if the status bit of the node corresponding to the routing identification code is available, the node corresponding to the routing identification code is used as an available FIX service node. For another example, if the status bit of the node corresponding to the routing identification code is disabled, the order change or cancellation is suspended until the status bit of the node corresponding to the routing identification code is available.

[0065] Optionally, some embodiments of the present disclosure may also obtain the access protocol parameters (access_protocol) and access endpoint parameters (end_point) of the selected FIX service node after selecting the node according to the weight values ​​of the available FIX service nodes. Furthermore, when the access protocol parameter is HTTP, the service instance defined by the access endpoint parameter is searched in the registration center for calling, and when the access protocol parameter is KAFKA, the order request is encapsulated as a KAFKA message, and the KAFKA message is delivered to the title (topic) defined by the access endpoint parameter. Further, the FIX service node will monitor the corresponding KAFKA topic and consume the order request message therein.

[0066] Optionally, in some embodiments of the present disclosure, when the status bit of the faulty FIX service node is restored to available, the weight value of the faulty FIX service node may be gradually increased until a preset weight is reached. Figure 4As shown, after the faulty FIX service node is restored, the embodiment of the present disclosure can set the route corresponding to the faulty FIX service node to be turned on through the management interface. It should be noted that in the initial stage of fault recovery, although the session_status status will be set to 1 to indicate that it is turned on, the session_priority will be initialized to 0. When it is confirmed that the FIX Session has been fully restored, the weight of the faulty route can be re-added as needed from the management interface, so that some new orders are routed to the FIX Session, thereby further ensuring the normal operation of the system.

[0067] Optionally, in some embodiments of the present disclosure, when FIX Session recovery is required, a recovery strategy can also be configured. For example, the weight value is set to 1 after 1 minute, the weight value is set to 10 after 10 minutes, and the weight value is set to 100 after 60 minutes. The advantage of such a setting is that it can reduce manual monitoring of the disk and is safer and more reliable.

[0068] Optionally, in some embodiments of the present disclosure, the health status of the FIX service node can be checked regularly or irregularly, so that if the health status is abnormal for many consecutive times, the FIX service node is actively removed through the control service, and the health status of the FIX service node is continuously monitored. When the status of the FIX service node returns to normal, if it is automatically closed by the control service, it is automatically turned on, thereby realizing automated operation and maintenance. Alternatively, other embodiments of the present disclosure can also check the health status of the service node through a registration center (such as zookeeper or consul), and remove the service node if it is unhealthy. Once the service node can be restarted, it will re-register with the registration center, and other business services can be called through service discovery.

[0069] Optionally, in some embodiments of the present disclosure, the dynamic routing table may also be backed up regularly and / or updated. Figure 5 As shown in the figure, since the dynamic routing table is a key configuration, it needs to be backed up regularly every day through the control service. If the dynamic routing table is manually configured from the management interface, a backup will also be generated. The backup method is to package all current data into a file format and upload it to AWS S3 (Simple Storage Service) for storage. At the same time, the control service will record all backups, so that you can select a backup from the management interface for recovery.

[0070] The disclosed embodiment provides a single point failure handling method, which sets the status bits of a dynamic routing table and a FIX service node so that when an order request is received, the FIX service node whose status bit is available in the dynamic routing table can be called to perform business processing, so that the faulty FIX service node whose status bit is disabled can be removed and restored, thereby ensuring the overall availability and normal operation of the trading system.
