Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or server that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In order to make the objects, technical solutions and advantages disclosed in the embodiments of the present invention more clearly apparent, the embodiments of the present invention are described in further detail below with reference to the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of the invention and are not intended to limit the embodiments of the invention.
In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present embodiment, "a plurality" means two or more unless otherwise specified.
In order to clearly explain the technical solutions described in the embodiments of the present invention, the embodiments of the present invention first explain related terms, technical background, and technical environment:
stream processing: stream processing is an important big data processing means, and the main characteristic is that the processed data comes continuously and in real time. Distributed stream processing is a fine-grained processing mode oriented to dynamic data, and continuously generated dynamic data are processed based on a distributed memory. The method plays an increasingly important role in large data processing due to the characteristics of high speed, high efficiency, low delay and the like of the data processing.
And (3) message transmission guarantee: there are generally three types of message transmission guarantees: at most once, At least once and exact once. The message transmission mechanism of the At most once is that each message is transmitted for zero time or once, namely the message may be lost; at least one success means that the message transmission may be repeated but not lost; the message transport mechanism of exact once is one and only one per message, i.e., the message transport is neither lost nor repeated.
Fault tolerance: failures in the flow processing framework can occur at various levels, such as network segments, disk crashes or node crashes. The stream processing framework should have the ability to recover from all such failures and re-consume from the last successful state (no dirty data).
Performance: latency (Latency), Throughput (Throughput), and Scalability (Scalability) are important metrics in stream processing applications.
Redis: the system is an open source log-type and Key-Value database which is written by using ANSI C language, supports network, can be based on memory and can also be persistent, and provides an application program structure of multiple languages. It supports relatively more Value types to be stored, including string, list, set, zset, and hash. These data types all support push/pop, add/remove, and intersect union and difference, and richer operations, and these operations are all atomic. On this basis, Redis supports various different ways of ordering. In order to ensure efficiency, data is cached in a memory, updated data is periodically written into a disk or modification operation is written into an additional recording file, and master-slave synchronization is realized on the basis.
A DAG: in graph theory, if a Directed graph cannot go from a vertex back to the point through several edges, the graph is a Directed Acyclic Graph (DAG). A directed acyclic graph may not be convertible to a tree because a directed graph does not necessarily form a ring from one point to another point through two routes, but any directed tree is a directed acyclic graph.
In order to describe the technical problems, technical solutions and technical effects actually solved by the embodiments of the present invention in more detail, a summary analysis is performed on the existing technical solution of distributed content stream processing in the embodiments of the present invention, and the existing technical solution of distributed content stream processing mainly includes three architectures, which are respectively:
(1) synchronization architecture
Each processing unit participating in stream processing in the content stream processing system processes the content set in sequence, and the execution of the processing unit downstream is triggered after the execution of the processing unit upstream is finished.
(2) Architecture based on message queue schema
The architecture based on the message queue mode is similar to the synchronous architecture, except that the execution of each processing unit in the content stream processing system is triggered by the message queue, and if a certain processing unit fails to execute, the content in the message queue is cyclically consumed by a downstream module for retry, although the architecture does not need to design the reprocessing logic in the service logic any more, the blocking of the message queue is easy to occur when the content which cannot be processed is encountered.
(3) Scanning framework
All contents related to the stream processing contents are uniformly stored in a preset storage space, each processing unit scans the storage space at regular time, executes the contents meeting the execution conditions, and writes the execution results into the storage space for a downstream processing unit to use.
The scanning architecture is actually a batch processing structure, and each processing unit scans the content meeting its own processing condition from the storage space at regular time, but this results in that each processing unit waits for the scanning process for most of the time in the whole content processing process, which increases the load of the storage space and increases the processing delay of the content stream processing system.
The actions of the processing units in the content stream processing systems with the three architectures have strong correlation with the service logic, and if the service logic changes, the processing units in the stream processing system may need to be modified, so that the content stream processing system can only be used in cooperation with a single service logic to provide content stream processing service for the single service logic, but cannot simultaneously provide content stream processing service for multiple service logics in parallel.
Further, due to the strong correlation between the content stream processing system and the service logic, the expansion of the service logic may result in a large modification of the content stream processing system, and as the complexity of the service logic gradually increases, it is likely that the maintenance cost of each processing unit in the content stream processing system is too high, and even the content stream processing system is difficult to adapt to the service logic and loses the use value.
In view of the above, embodiments of the present invention provide a content stream processing method, so as to provide a stream processing scheme decoupled from specific service logic, which is different from the existing content stream processing framework. First, the basic embodiment of the present invention provides one possible implementation environment of a content stream processing method.
Referring to fig. 1, the implementation environment includes: client 01, content console 03 and service server 05.
The content to be processed generated by one or more services in the client 01 is transmitted to the content console 03.
In the embodiment of the invention, a middlebox concept is used for constructing an implementation environment for content stream processing, and the middlebox aims to flexibly realize the support of various uncertain business rules and processing modes by designing a scientific technical framework so as to improve the cooperation efficiency of related business links.
The content center 03 processes various contents from the client 01 in a streaming manner, and sends the processing result to one or more service servers 05. The content center 03 encapsulates each processing unit participating in stream processing into a micro service, generates a micro service calling topology according to the requirements of each service server, and calls the micro service to process the content to be processed based on the micro service calling topology, so that the micro service is decoupled from the specific service through the micro service calling topology, and the purpose of providing the content stream processing service for a plurality of services in parallel is achieved.
The Client 01 is communicatively connected to the content center 03, and the Client 01 may communicate with the content center 03 based on a Browser/Server mode (Browser/Server, B/S) or a Client/Server mode (Client/Server, C/S). The client 01 may include: the physical devices may also include software running in the physical devices, such as applications, and the like. For example, the client 01 may run instant messaging software, micro video software, social software, image processing software, news software, and the like.
The content center 03 and the service server 05 may comprise a server operating independently, or a distributed server, or a server cluster composed of a plurality of servers.
Referring to fig. 2, a flow chart of a content stream processing method is shown, which may be implemented in the implementation environment of fig. 1, and the method may include:
s101, obtaining original content to be processed, generating a corresponding content object for the original content, and storing the content object in a preset storage space.
In a possible embodiment, the original content may come from multiple services, for example, the original content may come from various small video programs, small news programs, etc. in the client, and the actual source of the content to be processed is not limited in the embodiment of the present invention. Further, the specific form of the content to be processed is not limited, and the content to be processed may be one or more of pictures, texts, videos, animations and voices.
In one possible embodiment, to ensure that the entire original content is obtained, the generation logic of the content object may be triggered based on a signal trigger. When the content center station 03 acquires the warehousing signal, representing to start acquiring the original content; if the original content includes a plurality of sub-contents, the content center station 03 acquires a content processable signal when each sub-content is completely acquired, and the content center station 03 acquires a content object generation signal when all sub-contents in the original content are completely acquired. Different links of the original content are obtained to correspond to different signals, so that the obtaining process is clearer, and the probability of errors is reduced.
The content center station 03 may acquire a plurality of to-be-processed contents in parallel, generate a content object for each to-be-processed content, and store the content object.
In particular, the content object may include an object identification, original content, and a current processing state. The object identifier in the content object is the unique identifier of the content object, the current processing state represents the processing state of the content object, and if the content object is not processed by the content console 03, the current processing state of the content object is unprocessed; if the content object is being processed by the content broker 03, the current processing state of the content object is in process.
In a possible embodiment, the storage of the content object and the processing of the content object are concurrent, and in order to facilitate selection of the processing order of the content object in the content center station 03, in the embodiment of the present invention, the following design is performed on a content object generation logic, where the generating of the content object corresponding to the original content includes, as shown in fig. 3:
s1011, obtaining the grading correlation attribute of the original content.
Specifically, the score association attribute is one or a group of attributes that can characterize the importance or urgency of the original content. For example, the scored association attributes may include the source of the original content or the popularity of keywords in the original content. In other embodiments, the score association attribute may also include the acquisition time of the original content.
For example, if the original content is sourced from official media or a premium publisher account, it is determined that the original content has a higher value and, correspondingly, has a higher score. If the keyword popularity of the original content is higher, the original content is judged to have higher popularity and belong to hotspot information, and correspondingly, the original content also has higher score. Due to the design, the original content with different grading association attributes corresponds to different priorities, such as some news hot spot burst content or some authoritative content, and can be processed as soon as possible, so that the content can be rapidly distributed to a corresponding service server, and a target user can be reached more quickly.
And S1013, scoring the original content according to the scoring correlation attributes and a preset scoring algorithm.
And S1015, generating a content object according to the original content and the score.
S1017, generating an object identifier and a current processing state for the content object.
And S103, acquiring the target content object in the storage space.
Specifically, step S103 may be triggered to execute in response to a preset control instruction, or may be triggered to execute by a timer, which may be executed multiple times, and the embodiment of the present invention does not limit a specific trigger execution manner thereof.
In one possible implementation, the obtaining the target content object in the storage space, as shown in fig. 4, includes:
and S1031, traversing the storage space to obtain a content object set to be processed, wherein the current processing state of each content object in the content object set to be processed is unprocessed.
S1033, traversing the content object set to be processed to obtain a target content object set, wherein the score of the content object in the target content object set is larger than a preset score threshold value.
And S1035, determining each content object in the target content object set as a target content object.
In another possible implementation, the obtaining the target content object in the storage space, as shown in fig. 5, includes:
s1032, traversing the storage space to obtain a content object set to be processed, wherein the current processing state of each content object in the content object set to be processed is unprocessed.
S1034, arranging the content objects in the content object set to be processed according to the corresponding scores in a descending order to obtain a target content sequence.
And S1036, sequentially determining each content object in the target content sequence as a target content object.
The two embodiments can be used alone or in combination, which can ensure that the station always processes the more important content preferentially, and to achieve this technical effect, the score of the corresponding content object should dynamically reflect the current importance or urgency of the content object. The embodiment of the invention supports concurrent processing of the target content objects, and the processing flow of a single target object is taken as an example for explanation in the subsequent embodiment.
And S105, acquiring at least one service associated with the target content object, and acquiring the corresponding micro-service call topology according to the service to obtain a micro-service call topology set corresponding to the target content object.
In the embodiment of the invention, different target content objects may be associated with different services, and each service has a micro-service call topology corresponding to the service. Therefore, before obtaining the micro-service invocation topology corresponding to the service according to the service, the method further includes a step of constructing the micro-service invocation topology corresponding to each service, where the constructing the micro-service invocation topology corresponding to each service is performed for each service, as shown in fig. 6, and includes:
s1, packaging each processing link of content stream processing to obtain a micro-service set, wherein each micro-service in the micro-service set is independently called to realize an atomic processing function.
Different from a framework in which a service is coupled with each processing link in content stream processing in the prior art, in order to achieve the purpose of decoupling, in the embodiment of the present invention, each processing action in the content stream processing process is encapsulated to obtain a single function execution body capable of independently performing an atomic content processing function.
And S3, responding to the service subscription request, and acquiring the content stream processing logic corresponding to the service.
And S5, obtaining the micro-service call topology corresponding to the service according to the content flow processing logic corresponding to the service and the micro-service set.
Specifically, the micro-service invocation topology points to a micro-service subset required for implementing the content stream processing logic corresponding to the service, and an invocation dependency relationship between micro-services in the micro-service subset is recorded. In one possible implementation, the microservice invocation topology may be represented by a directed acyclic graph.
Referring to FIG. 7, a schematic diagram of the execution logic of a micro service invocation topology in a set of micro service invocation topologies is shown. The micro-service calling topology set comprises two micro-service calling topologies, namely a micro-service calling topology A and a micro-service calling topology B, and each micro-service in the micro-service calling topology A and the micro-service calling topology B is sequentially scheduled according to the arrow indication.
The micro service invocation topology a and the micro service invocation topology B may each include three types of micro services, as detailed below:
(1) micro-services that are scheduled by different scheduling services to obtain different invocation results.
For example, the service calling topology a and the micro-service calling topology B both include a watermark micro-service and a cover micro-service, and the watermark micro-service and the cover micro-service can be respectively called by the scheduling service of the micro-service calling topology a and the scheduling service of the micro-service calling topology B, so that two groups of watermarks and two groups of covers are obtained.
(2) The microservice of the call results may be shared.
For example, the service invocation topology a and the micro-service invocation topology B both include a tag micro-service, which can be invoked only once by the scheduling service of the micro-service invocation topology a or the scheduling service of the micro-service invocation topology B to obtain a tag, and the tag can be shared by other scheduling services to save the scheduling overhead.
(3) A microservice scheduled by a single scheduling service.
Such as svr2, svr4, and svr7 in service invocation topology a and svr3, svr6, and svr8 in service invocation topology B.
