Detailed Description
Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that the description is illustrative only and is not intended to limit the scope of the present disclosure. In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present disclosure.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The terms "comprises," "comprising," and the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.
All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It is noted that the terms used herein should be interpreted as having a meaning that is consistent with the context of this specification and should not be interpreted in an idealized or overly formal sense.
Where a convention analogous to "at least one of A, B and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B and C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.). Where a convention analogous to "A, B or at least one of C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B or C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.).
With the development of the internet, artificial intelligence is becoming a key component in the enterprise transformation process, and a machine learning platform is developed in response to the reduction of the threshold of machine learning. In the development process of the machine learning platform, a large number of efficient machine learning algorithm components are accumulated, and based on the components, modeling personnel can quickly establish a model to realize a business process and solve specific problems. Among them, the modeling method of the drag-type task flow becomes one of the mainstream in the industry.
Aiming at the same service requirement, multi-person collaborative modeling is often needed, and the situation that multiple persons edit the same directed acyclic graph simultaneously and online inevitably occurs when the multi-person collaborative co-modeling is carried out. Sometimes, problems of repeated task execution, model coverage and the like can be caused due to untimely communication, so that the modeling time of modeling personnel is wasted, the running resources of the platform are consumed, and poor interaction experience is brought to users.
At present, although a check-in check-out mechanism can be adopted, namely the directed acyclic graph is locked during editing and is only edited by a current user, other users enter the current directed acyclic graph into a read-only mode, an HTTP request and a window event are sent through JavaScript to complete interaction with a server, and the locking state of the directed acyclic graph is set. If the problems of browser non-response, network abnormity and the like are encountered, the browser cannot send an unlocking request to the server in time, and the situations that the directed acyclic graph is locked, the model cannot be stored in time and the like are caused. To a certain extent, although the check-in and check-out mechanism can solve the problems of repeated execution of tasks and covered models, the problems of locking of the directed acyclic graph, incapability of storing the models in time, difficulty in timely acquiring the check-out information of the directed acyclic graph by a read-only user and the like still exist.
Fig. 1 schematically shows the working principle of the HTTP protocol.
As shown in fig. 1, the HTTP protocol is a stateless, connectionless, unidirectional application layer protocol, and adopts a request/response model, where a communication request can only be initiated by a client and a server responds to the request. In the related art, only the HTTP protocol is adopted, and the server cannot actively initiate a message to the client. The read-only user is difficult to achieve synchronization with the editing user, the editing user adjusts and modifies the model, the read-only user cannot sense the model and only can read the model state when entering the directed acyclic graph or quit modeling and re-enter the directed acyclic graph to re-acquire the latest model state. And if the client side adopts a mechanism of regularly refreshing the directed acyclic graph, the long polling is realized through frequent asynchronous JavaScript and XML (AJAX) requests. Under the conditions of small operator number and uncomplicated connection, the read-only user can be synchronized with the editing user; however, under the conditions of large number of operators and complex connection, a timing refreshing mechanism is not a little burden for both the client and the server. The timing refresh mechanism is not only inefficient, but also very resource-wasting.
In view of the above problems, the embodiments of the present disclosure add a heartbeat mechanism on the basis of a check-in check-out mechanism, and implement interaction between a server and a client by using a duplex full-duplex communication protocol, so as to obtain a collaborative modeling method based on collaborative modeling of a directed acyclic graph. After a user locks the directed acyclic graph and enters an editing mode, other users enter the directed acyclic graph into a read-only mode, and when the user is edited to store a model, run an operator and stop the operator, the directed acyclic graph of the read-only user is updated to be in a latest state in real time, so that the model synchronization of the editing mode and the read-only mode is achieved; the user exits the editing mode, the directed acyclic graph is set to be in an unlocked state, and the read-only user of the current directed acyclic graph is informed; the user loses connection with the current locking directed acyclic graph due to page jumping, browser closing or network abnormity, the directed acyclic graph can be normally and automatically unlocked, data is automatically stored in the database, and the read-only user of the current directed acyclic graph is informed.
Specifically, embodiments of the present disclosure provide a collaborative modeling method, a collaborative modeling apparatus, an electronic device, a computer-readable storage medium, and a computer program product. The collaborative modeling method comprises the following steps: acquiring the state of a directed acyclic graph; under the condition that the state of the directed acyclic graph is a locked state, responding to a model editing instruction of a first user in an editing mode, and updating the model in the database; pushing model update information to a second user in a read-only mode based on the communication connection, wherein the model update information includes a state of the updated model; and responding to an unlocking instruction of the first user, setting the state of the directed acyclic graph as an unlocked state, and ending the modeling process of the first user.
FIG. 2 schematically illustrates an exemplary system architecture 200 to which the collaborative modeling approach may be applied, according to an embodiment of the present disclosure. It should be noted that fig. 2 is only an example of a system architecture to which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, and does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.

Network 204 may include various connection types, such as wired and/or wireless communication connections, and so forth. A user may interact with a server 205 over a network 204 using terminal devices 201, 202, 203 based on a communication protocol to receive or send messages or the like.

FIG. 3 schematically shows a flow chart of a collaborative modeling method according to an embodiment of the present disclosure.
As shown in fig. 3, the method includes operations S310 to S340.
In operation S310, a state of a directed acyclic graph is acquired.
According to the embodiment of the disclosure, the states of the directed acyclic graph include a locked state and an unlocked state, and the states of the directed acyclic graph can be switched after receiving a corresponding instruction.
In operation S320, in the case where the state of the directed acyclic graph is the locked state, the model in the database is updated in response to the model edit instruction of the first user in the edit mode.
According to the embodiment of the disclosure, in the case that the directed acyclic graph is in the locked state, the server responds to only the relevant instruction of the first user in the editing mode. After receiving a model editing instruction of the first user, the server may store the model in the current directed acyclic graph into the database, so as to update the model in the database.
In operation S330, model update information is pushed to a second user in a read-only mode based on the communication connection.
According to an embodiment of the present disclosure, the model update information may include a state of the updated model and may further include user information of the first user.
According to embodiments of the present disclosure, the communication connection may include a first communication connection between the first user and the server, and a second communication connection between the second user and the server. Through the first communication connection, the server may obtain user information of the first user, such as identification information of the first user, an address of the first user, and the like. After receiving the instruction of the first user, the server can push the user information of the first user and the updated model to the second user through the second communication connection, so that the second user can know the latest state of the model.
In operation S340, in response to the unlocking instruction of the first user, the state of the directed acyclic graph is set to the unlocked state, and the modeling process of the first user is ended.
According to the embodiment of the disclosure, under the condition that the directed acyclic graph is in a locked state, the change of the model by the first user in the editing mode is pushed to the second user in the read-only mode in real time through communication connection, so that the real-time synchronization of the model is realized, the problems of repeated execution of task tasks and untimely synchronization of the model in the collaborative modeling process are avoided, and the user experience of the modeling process is improved.
The method shown in fig. 3 is further described with reference to fig. 4-6 in conjunction with specific embodiments.
FIG. 4 schematically shows a schematic diagram of a collaborative modeling flow according to another embodiment of the present disclosure.
As shown in fig. 4, first, when receiving a request for accessing the directed acyclic graph from a modeler, the server performs a method as operation S401 to determine a state of the directed acyclic graph, so as to determine an operating mode of the modeler.
According to an embodiment of the present disclosure, the condition of obtaining the directed acyclic graph may be a state of obtaining the directed acyclic graph based on the dictionary table. The dictionary table may be a data dictionary table created when creating the directed acyclic graph or during using the directed acyclic graph, and the data dictionary table may be as shown in table 1, and includes identification information of the directed acyclic graph, a state of the directed acyclic graph, identification information of the first user, and an address of the first user.
TABLE 1
According to embodiments of the present disclosure, the states of a directed acyclic graph may include a locked state and an unlocked state. Determining a modeling user as a first user under the condition that the state of the directed acyclic graph is an unlocked state; and determining the modeling user as a second user in the case that the state of the directed acyclic graph is the locking state.
According to the embodiment of the disclosure, when the modeling user is the first user, the identification information of the first user and the address of the first user may be stored in the dictionary table shown in table 1, and a lock instruction is waited for.
According to the embodiment of the disclosure, the locking instruction may be initiated by the first user actively, or may be automatically executed by the server after a preset time after the first user appears. For example, when the first user accesses the directed acyclic graph in the unlocked state, the first user directly starts editing the model without sending a lock instruction, and the server may directly lock the directed acyclic graph after 30 seconds after detecting the access of the first user.
In operation S402, the directed acyclic graph is set to a locked state, and an edit mode is entered.
According to the embodiment of the disclosure, when the first user is in the editing mode, before the server responds to and executes the model editing instruction of the first user, the server may further verify the user information as in operation S403, and compare the user information of the instruction initiating user with the user information of the first user recorded in the dictionary table. If so, executing the method of operation S404, responding and executing the model editing instruction; if not, the method of operation S405 is executed, and a read-only mode is entered, and the directed acyclic graph is waited to be unlocked.
According to embodiments of the present disclosure, the model edit instruction may include a save model instruction, a run operator instruction, and a stop operator instruction.
According to the embodiment of the disclosure, after the first user enters the editing mode, the server may further establish a communication connection with the first user based on a duplex communication protocol, and through the communication connection, the server may actively acquire the model being edited by the first user.
According to the embodiment of the disclosure, in the case of receiving any one of the saving model instruction, the running operator instruction and the stopping operator instruction of the first user, the model in the edition of the first user can be used for replacing the model in the database.
When the modeling user is the second user, the method may also enter the read-only mode, for example, in operation S405, and wait for unlocking the directed acyclic graph.
According to an embodiment of the present disclosure, the server may establish a communication connection with the second user based on a duplex communication protocol while the second user is in the read-only mode. When a model editing instruction of a first user is received, the server can actively send the updated model in the database and the user information of the first user to a second user through the communication connection, so that the real-time synchronization of the model is realized.
According to the embodiment of the disclosure, when the second user is in the read-only mode, the related information of the directed acyclic graph can be checked, but the server does not respond to the locking instruction, the model editing instruction and the unlocking instruction of the second user.
In operation S406, an unlock instruction is responded to and executed.
According to the embodiment of the disclosure, after the server executes the unlocking instruction, the first user and the second user can quit the editing mode and the read-only mode respectively, the communication connection between the first user and the second user is disconnected, the directed acyclic graph is set to be in an unlocked state, and the modeling process of the first user is finished. After the directed acyclic graph is unlocked, the second user may initiate a request for accessing the directed acyclic graph again to start the modeling process. In particular, when the number of the second users in the read-only mode is one, the users can directly enter the editing mode.
According to the embodiment of the disclosure, the accessed modeling users are classified based on the state of the directed acyclic graph, so that the situation that modeling operation is carried out by multiple persons at the same time can be effectively avoided, the waste of resources is reduced, and the model is prevented from being covered.
Fig. 5 schematically shows a timing diagram of first user and second user status updates according to another embodiment of the present disclosure.
As shown in fig. 5, after the directed acyclic graph is locked by the first user and enters the editing mode, the second user enters the directed acyclic graph as the read-only mode, and when the first user saves the model, runs the operator, and stops the operator, the directed acyclic graph of the second user is updated to the latest state in real time, so that the model synchronization between the editing mode and the read-only mode is achieved; the first user exits the editing mode, the directed acyclic graph is set to be in an unlocked state, and a second user of the current directed acyclic graph is informed; the first user loses connection with the current locking directed acyclic graph due to page jumping, browser closing or network abnormity, the directed acyclic graph can be normally and automatically unlocked, data is automatically stored in the database, and the second user of the current directed acyclic graph is informed.
Fig. 6 schematically shows a schematic diagram of the operation principle of the WebSocket protocol.
As shown in fig. 6, the WebSocket protocol is implemented based on the TCP protocol, and is a protocol for performing full duplex communication on a single TCP connection, and the client and the server only need to complete one handshake, and a persistent connection can be established between the client and the server, so that data exchange becomes simpler, and the server is allowed to actively push data to the client.
In the collaborative modeling process according to another embodiment of the present disclosure, the duplex full duplex communication protocol may be a WebSocket protocol. Based on the protocol, after the server establishes the first HTTP connection with the first user or the server establishes the first HTTP connection with the second user, subsequent data exchange does not need to resend the HTTP request. Compared with the HTTP protocol, the protocol does not need to set a polling mechanism in the server and does not need to repeatedly establish HTTP connection, so that bandwidth resources are saved.
According to embodiments of the present disclosure, a hash table (convurrenthashmap) may be created for storing user information of a modeling user. For example, an edit hash table (writeMap) may be created for storing user information of a first user and a read-only hash table (readMap) may be created for storing user information of a second user. The primary key (key) of the hash table is identification information (UUID) of the directed acyclic graph, and the specific value is a list for storing the identification information of the directed acyclic graph, the identification information of the first user or the second user, the address of the first user or the second user, and session information for storing the first user or the second user.
In another embodiment of the present disclosure, after establishing the WebSocket connection with the first user, the method further includes storing the identification information of the first user, the address of the first user, and the session information with the first user in an edit hash table; after establishing the WebSocket connection with the second user, the method also comprises the step of storing the identification information of the second user, the address of the second user and the session information of the second user into the read-only hash table.
According to the embodiment of the disclosure, after the WebSocket connection is established with the first user, the server can also verify the information in the hash table. For example, it may be determined whether the identification information of the directed acyclic graph exists in the edit hash table; if the hash table does not exist, adding and editing the identification information of the directed acyclic graph into the hash table; and if so, adding the identification information of the directed acyclic graph into the read-only hash table. Therefore, when the model information in the database changes, the server can push the relevant information to the modeling user in the read-only mode.
According to the embodiment of the disclosure, after the WebSocket connection between the first user and the second user is completed, the server can realize the synchronization of the models and the information push function. For example, when the first user saves, runs, and stops the directed acyclic graph, the server may obtain the operation information, and send the latest state of the model to the second user corresponding to the directed acyclic graph in the read-only hash table.
According to the embodiment of the disclosure, when it is detected that the WebSocket connection is disconnected, the server can also determine the user corresponding to the disconnected WebSocket connection based on the session information, and set the state of the directed acyclic graph to be the unlocked state when the user corresponding to the disconnected WebSocket connection is the first user. For example, it may be determined whether the session information of the server is consistent with the session information of the directed acyclic graph in the edit hash table; if the two states are consistent, it can be considered that the first user has behaviors such as disconnection, shutdown and the like, which causes the abnormal disconnection of the WebSocket connection, at this time, information that the first user exits the editing mode can be pushed to the second user of the directed acyclic graph in the read-only hash table, model data is synchronized, all WebSocket connections of the directed acyclic graph are closed, and the directed acyclic graph is set to be in an unlocked state; on the other hand, if the user corresponding to the disconnected WebSocket connection is detected to be the second user, the WebSocket connection with the second user is closed.
According to the embodiment of the disclosure, by establishing the heartbeat mechanism by adopting the WebSocket protocol, the problems that the directed acyclic graph is locked and cannot be edited subsequently due to the fact that the modeling is quitted due to abnormal conditions such as network abnormality and browser unresponsiveness after a user locks the directed acyclic graph are solved, and meanwhile, the user in a read-only mode can be helped to update the state of the synchronous model in real time.
According to the embodiment of the disclosure, through the check-in and check-out mechanism and the heartbeat mechanism, the user can model in an immersive mode without paying attention to the influence of other factors, meanwhile, the resource waste of repeated modeling is avoided, and a better modeling environment and interaction experience are provided for the user.
