The above technical solutions of the embodiments of the present invention are described in detail below with reference to specific application examples, and reference may be made to the foregoing related descriptions for technical details that are not described in the implementation process.
In the prior art, as shown in fig. 3, a live broadcast list and details of a commodity are all stored in an e-commerce department, and a live broadcast department (a background) is responsible for direct interactive operation with a main broadcast and a user, high performance and high availability are required to be ensured, otherwise, experience influence of the main broadcast and the user on revenue is reduced, and as basic data are all provided by the e-commerce department and an interface of the basic data cannot bear large-flow impact (the highest guarantee is 100 qps), the e-commerce live broadcast platform needs a guarantee design with high performance, high availability and data consistency. The summary is as follows:
1) The live E-commerce system comprises a central control system, a marketing system and a live inventory, wherein commodity data in the live inventory of the E-commerce system are stored in the E-commerce system.
2) Live E-commerce is responsible for capacity and commodity data consistency.
3) E-commerce live broadcast commodity data consistency relies on E-commerce notifications.
Compared with the prior art, the method is designed for the high performance of the E-commerce live broadcast shopping cart, and a local cache and second-level cache (distributed cache) automatic refreshing mechanism and department asynchronous notification (asynchronous message queue) of shopping cart service are accessed according to the characteristics of the current E-commerce live broadcast technical architecture and cross-department interaction, so that the data consistency and the usability in the shopping cart are guaranteed.
The whole architecture of the invention is shown in fig. 4, the whole flow is shown in fig. 5, and live e-commerce live broadcast specifically comprises live broadcast related parts and live broadcast commodity shopping cart service. All request flow related to live telecast of the E-commerce comes to the gateway first, after passing through the gateway, a part of the request flow is sent to live telecast shopping cart service (user requests of shopping cart service related to live broadcast products are directly pushed to shopping cart service), and the other part of the request flow is sent to live telecast related parts (user requests of watching live broadcast rooms are directly pushed to live broadcast rooms). Wherein the live related parts include: live core services, integrated services, and interactivity aspects; live core services include, for example: switching on and off live broadcasting, and watching live broadcasting service; the integrated service includes activity aspects, such as leaderboards; the invention is characterized in that live E-commerce service, namely service related to commodities in a shopping cart. Wherein the services related to the items in the shopping cart include:
1. live basic service: broadcasting, closing and broadcasting information in a live room;
2. e-business-small store: the method refers to a main source party of direct-broadcast commodities, and integrates commodities of all (on-line) suppliers;
3. the user center: information containing users, such as user nicknames and the like;
im (instant messaging system): for example, sending commodity to set up and explaining message, and the mobile phone client can do corresponding operation instantly after receiving the message.
The core design for a goods related service in a shopping cart (i.e., a shopping cart service) is:
1) Capacity expansion, capacity read by a user side (user), and capacity written by a main broadcasting side (main broadcasting core service and integrated service);
2) For live product downstream capacity protection, downstream e-commerce (live product supplier) modules may not resist volume;
3) The consistency and timeliness of the updated data are guaranteed.
1. Capacity expansion design
As shown in fig. 6 and 7, according to a user request of a shopping cart service related to live broadcast products, relevant live broadcast product data is obtained from a local cache of the shopping cart service; and the local cache of the shopping cart service acquires the product updating data from a preset second-level cache and updates the product updating data instantly, and the time effectiveness of the local cache of the shopping cart service is smaller than that of the second-level cache. That is, the reading capacity of the user side is guaranteed by a local cache and a second-level cache (redis distributed cache) of the shopping cart, and downstream e-commerce department services cannot be directly punctured in the e-commerce live broadcast process. The second-level cache is a redis distributed cache, monitors the data concurrency amount of the shopping cart service in real time, and expands the second-level cache when the data concurrency amount exceeds the preset processing capacity.
The write capacity of the anchor end depends on the maximum qps (request per second) that the e-commerce live broadcast room can bear, specifically: and a local cache and an expandable redis distributed cache are arranged in the live broadcast room, and the data generated during live broadcast are jointly stored through the local cache and the expandable redis distributed cache in the live broadcast room.
2. Design of data consistency & timeliness, as shown in FIG. 8, FIG. 9, FIG. 10
The data consistency is ensured by combining [ notification update ] + [ cache invalidation ]; namely: the shopping cart service periodically inquires and acquires product updating data from a preset interface provided by a live broadcast product supplier, and updates the acquired product updating data to a second-level cache; and after the local cache fails, the product updating data is obtained from the second-level cache to update the live broadcast product data, and/or the local cache periodically obtains the product updating data from the second-level cache to update the live broadcast product data.
1) The E-business (live broadcast product supplier) sends a message to a distributed publishing and subscribing message system kafka when the data is updated, the E-business live broadcast realizes the data updating through consuming the message, the data updating is processed asynchronously, and the updating timeliness is 3s for example; the shopping cart service acquires a message carrying product updating data from the asynchronous message queue, and stores the product updating data in the message into a second-level cache of the shopping cart service respectively; the asynchronous message queue is a distributed publish-subscribe message system kafka, and the live broadcast product supplier packages the product update data into a message and sends the message to the asynchronous message queue, wherein the message carrying the product update data is the message carried by the live broadcast product supplier.
2) And (4) cache invalidation, namely updating when a local cache is invalidated, wherein the second-level cache is used as a bottom-storing mechanism, and the timeliness of the bottom-storing mechanism is 30s. I.e., the local cache of the shopping cart service has a smaller age than the second level cache.
3. Technical support objective
1) Mainly reading the reactance amount of a Redis distributed cache;
2) The simple writing service is guaranteed through two aspects, namely, the Mysql database is optimized; secondly, the quality requirement of the shopping cart service is determined and monitored; three complex write services, handled through asynchronous message queues;
3) In a system performance monitoring scene, when the concurrency exceeds the preset processing capacity, the service RT TP99 monitors that the redis distributed cache is expanded, so that the potential performance hazard can be found and solved in time. The application program interface API TP99<200ms.
The beneficial effects obtained by the invention are as follows:
the local cache and the distributed secondary cache are adopted to jointly meet the data updating support of the shopping cart service, the problem that a data source (live broadcast product supplier) is broken down and the data updating is inconsistent is avoided, the real-time performance of the data source and the data updating is guaranteed, and the secondary cache has the transverse capacity expansion and reduction capacity.
Compared with the E-business framework in the internet at present, the system has a high availability and high stability framework, shopping cart service actively accesses a data source (periodically inquires and obtains product updating data from a preset interface provided by a live broadcast product supplier) in a short time, refreshes a local memory and a distributed cache (second-level cache), and actively informs a modification and automatic invalidation bottom-holding mechanism in combination with the data source supplier, so that the large-flow live broadcast is ensured not to break down the data source, the data consistency is ensured, and the transverse expansion and contraction capacity can be supported.
