The following describes a method for processing the data request in conjunction with several specific application scenarios.
With application scenario 1, for data request a of service type a, first, data request a is processed by service node a1, then, based on the processing result of service node a1, data request a is processed by service node a2, then, based on the processing result of service node a2, data request a is processed by service node A3, and then, based on the processing result of service node A3, data request a is processed by service node a 4.
Metadata A is configured for service type A, which may include service type A, execution order 1 for service node A1 (representing service node A1 first execution), execution order 2 for service node A2 (representing service node A2 second execution), execution order 3 for service node A3 (representing service node A3 third execution), and execution order 4 for service node A4 (representing service node A4 fourth execution). In summary, based on the execution sequence of each service node, it may be determined that the topology sequence executed last is: 1234.
further, in the service node set corresponding to service type a, service node a1, service node a2, service node A3, and service node a4 may be included, that is, service node a1, service node a2, service node A3, and service node a4 are all used to process data request a corresponding to service type a.
In the application scenario, the method for processing the data request in application scenario 1 may include:
step a1, obtaining a service node set corresponding to the service type a, where the service node set includes a service node a1, a service node a2, a service node A3, and a service node a4, and the service node a1, the service node a2, the service node A3, and the service node a4 are used to process a data request a corresponding to the service type a.
Step a2, obtaining metadata corresponding to the service node set according to the service type a, where the metadata a includes the service type a, and thus the metadata corresponding to the service node set may be the metadata a.
Step a3, obtaining the execution sequence of each service node in the service node set according to the metadata A.
For example, since metadata a includes execution order 1 of service node a1, execution order 2 of service node a2, execution order 3 of service node A3, and execution order 4 of service node a4, based on metadata a, it may be determined that the execution order of service node a1 in the service node set is 1, the execution order of service node a2 is 2, the execution order of service node A3 is 3, and the execution order of service node a4 is 4.
Step a4, determining the path information corresponding to the service node set according to the execution sequence of each service node.
For example, since the execution order of the service node a1 is 1, the execution order of the service node a2 is 2, the execution order of the service node A3 is 3, and the execution order of the service node a4 is 4, that is, the service node a1 is the first service node to compute a path, the service node a2 is the second service node to compute a path, the service node A3 is the third service node to compute a path, and the service node a4 is the fourth service node to compute a path, the path information corresponding to the service node set may be the service node a 1-the service node a 2-the service node A3-the service node a4, which is shown in fig. 3A and is an example of the path information.
Step a5, determining the data processing mode corresponding to each service node according to the path information.
For example, referring to the path information shown in fig. 3A, for the service node a1, since the service node a1 is the first service node for calculating the path, that is, the service node a1 does not have an adjacent service node in front of it and has an adjacent service node a2 behind it, the data processing manner for determining the service node a1 includes a receiving condition, and the receiving condition is used to instruct to send the processing result of the service node a1 to the service node a 2.
For the service node a2, since the service node a2 is the second service node of the computed path, that is, the service node a2 has an adjacent service node a1 in front of it and an adjacent service node A3 behind it, it is determined that the data processing manner of the service node a2 includes a trigger condition and a receiving condition, the trigger condition is used to indicate that after receiving the processing result of the service node a1, the data request is processed based on the processing result of the service node a1, and the receiving condition is used to indicate that the processing result of the service node a2 is sent to the service node A3.
For the service node A3, since the service node A3 is the third service node of the computation path, that is, the service node A3 has an adjacent service node a2 in front of it and an adjacent service node a4 behind it, it is determined that the data processing manner of the service node A3 includes a trigger condition and a receiving condition, the trigger condition is used to indicate that after receiving the processing result of the service node a2, the data request is processed based on the processing result of the service node a2, and the receiving condition is used to indicate that the processing result of the service node A3 is sent to the service node a 4.
For the service node a4, since the service node a4 is the last service node of the computation path, that is, the service node a4 has an adjacent service node A3 in front of it and an adjacent service node in the back of it, it is determined that the data processing manner of the service node A3 includes a trigger condition, and the trigger condition is used to indicate that, after receiving the processing result of the service node A3, the data request is processed based on the processing result of the service node A3.
Step a6, sending the data processing mode corresponding to each service node to the service node.
For example, the receive condition of service node A1 is sent to service node A1, the trigger condition and receive condition of service node A2 are sent to service node A2, the trigger condition and receive condition of service node A3 are sent to service node A3, and the trigger condition of service node A4 is sent to service node A4.
And step a7, each service node processes the data request by using a data processing mode.
For example, after receiving the data request a for service type a, the first service node corresponding to service type a, i.e., service node a1, is determined, and the data request a is sent to service node a 1.
After receiving the data request a, the service node a1 may process the data request a to obtain a processing result of the service node a 1. Based on the reception condition of the service node a1, the service node a1 may send the data request a and the processing result of the service node a1 to the service node a 2.
After the service node a2 receives the data request a and the processing result of the service node a1, based on the trigger condition of the service node a2, the service node a2 processes the data request a based on the processing result of the service node a1, and obtains the processing result of the service node a 2. Based on the reception condition of the service node a2, the service node a2 transmits the data request a and the processing result of the service node a2 to the service node A3.
After the service node A3 receives the data request a and the processing result of the service node a2, based on the trigger condition of the service node A3, the service node A3 processes the data request a based on the processing result of the service node a2, and obtains the processing result of the service node A3. Based on the reception condition of the service node A3, the service node A3 transmits the data request a and the processing result of the service node A3 to the service node a 4.
After the service node a4 receives the data request a and the processing result of the service node A3, based on the trigger condition of the service node a4, the service node a4 processes the data request a based on the processing result of the service node A3 to obtain the processing result of the service node a4, and thus, the processing procedure of the data request a is completed.
With application scenario 2, for data request B of service type B, first, data request B may be processed by serving node B1, then, based on the processing result of serving node B1, data request B may be processed in parallel by serving node B2 and serving node B3, and then, based on the processing result of serving node B2 and the processing result of serving node B3, data request B may be processed by serving node B4. Metadata B is configured for service type B, which includes service type B, execution order 1 of serving node B1, execution order 2 of serving node B2, execution order 2 of serving node B3, and execution order 3 of serving node B4. In summary, based on the execution sequence of each service node, it may be determined that the topology sequence executed last is: 1223.
in the application scenario, the method for processing the data request of the application scenario 2 may include:
step B1, obtaining a service node set corresponding to service type B, where the service node set includes service node B1, service node B2, service node B3, and service node B4, and service node B1, service node B2, service node B3, and service node B4 are used to process data request B corresponding to service type B.
Step B2, obtaining the metadata corresponding to the service node set according to the service type B, where the metadata B includes the service type B, and therefore the metadata corresponding to the service node set may be the metadata B.
And B3, acquiring the execution sequence of each service node in the service node set according to the metadata B.
For example, it is determined that the execution order of the serving node B1 in the set of serving nodes is 1, the execution order of the serving node B2 is 2, the execution order of the serving node B3 is 2, and the execution order of the serving node B4 is 3.
And b4, determining the path information corresponding to the service node set according to the execution sequence of each service node.
For example, since the execution order of the serving node B1 is 1, the execution order of the serving node B2 is 2, the execution order of the serving node B3 is 2, and the execution order of the serving node B4 is 3, the path information corresponding to the serving node set may be serving node B1-serving node B2 or serving node B3-serving node B4.
Referring to fig. 3B, an example of path information corresponding to a service node set is shown.
And b5, determining the data processing mode corresponding to each service node according to the path information.
For example, referring to the path information shown in fig. 3B, for serving node B1, since serving node B1 is the first serving node to calculate the path, that is, serving node B1 does not have an adjacent serving node in front of it, and has an adjacent serving node B2 and serving node B3 behind it, determining the data processing manner of serving node B1 may include a receiving condition, where the receiving condition is used to instruct to send the processing result of serving node B1 to serving node B2 and send the processing result of serving node B1 to serving node B3.
The serving node B2 has a neighboring serving node B1 in front of it and a neighboring serving node B4 behind it, so the data processing mode of the serving node B2 includes a trigger condition and a receiving condition, the trigger condition is used to indicate that after receiving the processing result of the serving node B1, the data request is processed based on the processing result of the serving node B1, and the receiving condition is used to indicate that the processing result of the serving node B2 is sent to the serving node B4.
The serving node B3 has a neighboring serving node B1 in front of it and a neighboring serving node B4 behind it, so the data processing mode of the serving node B3 includes a trigger condition and a receiving condition, the trigger condition is used to indicate that after receiving the processing result of the serving node B1, the data request is processed based on the processing result of the serving node B1, and the receiving condition is used to indicate that the processing result of the serving node B3 is sent to the serving node B4.
The serving node B4 has neighboring serving node B2 and serving node B3 in front of it and neighboring serving node B in back of it, and therefore, it is determined that the data processing manner of the serving node B3 includes a trigger condition, where the trigger condition is used to indicate that, after receiving the processing result of the serving node B2 and the processing result of the serving node B3, the data request is processed based on the processing result of the serving node B2 and the processing result of the serving node B3.
And b6, sending the data processing mode corresponding to each service node to the service node.
And b7, each service node processes the data request by using a data processing mode.
For example, the serving node B1, upon receiving the data request B, may process the data request B to obtain a processing result for the serving node B1. Based on the reception condition of the serving node B1, the serving node B1 transmits the data request B and the processing result of the serving node B1 to the serving node B2 and the serving node B3.
After serving node B2 receives the processing results of data request B and serving node B1, based on the trigger condition of serving node B2, serving node B2 processes data request B based on the processing result of serving node B1, and obtains the processing result of serving node B2. Based on the reception condition of the serving node B2, the serving node B2 transmits the data request B and the processing result of the serving node B2 to the serving node B4.
After serving node B3 receives the processing results of data request B and serving node B1, based on the trigger condition of serving node B3, serving node B3 processes data request B based on the processing result of serving node B1, and obtains the processing result of serving node B3. Based on the reception condition of the serving node B3, the serving node B3 transmits the data request B and the processing result of the serving node B3 to the serving node B4.
After the serving node B4 receives the data request B, the processing result of the serving node B2, and the processing result of the serving node B3, based on the trigger condition of the serving node B4, the serving node B4 processes the data request B based on the processing result of the serving node B2 and the processing result of the serving node B3 to obtain the processing result of the serving node B4, and thus, the processing procedure of the data request B is completed. It should be noted that the trigger condition is satisfied after the processing result of the serving node B2 and the processing result of the serving node B3 are received.
Application scenario 3, for data request C of service type C, first, data request C may be processed by serving node C1, and then, based on the processing result of serving node C1, data request C may be processed in parallel by serving node C2, serving node C3, and serving node C4. The metadata C is configured for the service type C, and may include the service type C, an execution order 1 of the service node C1, an execution order 2 of the service node C2, an execution order 2 of the service node C3, and an execution order 2 of the service node C4. In summary, based on the execution sequence of each service node, it may be determined that the topology sequence executed last is: 1222.
in the application scenario, the method for processing the data request of the application scenario 3 may include:
and d1, acquiring a service node set corresponding to the service type C, wherein the service node set comprises a service node C1, a service node C2, a service node C3 and a service node C4, and the service node C1, the service node C2, the service node C3 and the service node C4 are used for processing the data request C corresponding to the service type C.
Step d2, obtaining the metadata corresponding to the service node set according to the service type C, where the metadata C includes the service type C, and thus the metadata corresponding to the service node set may be the metadata C.
And d3, acquiring the execution sequence of each service node in the service node set according to the metadata C.
For example, it is determined that the execution order of the service node C1 in the service node set is 1, the execution order of the service node C2 is 2, the execution order of the service node C3 is 2, and the execution order of the service node C4 is 2.
And d4, determining the path information corresponding to the service node set according to the execution sequence of each service node.
For example, since the execution order of the service node C1 is 1, the execution order of the service node C2 is 2, the execution order of the service node C3 is 2, and the execution order of the service node C4 is 2, the path information corresponding to the service node set may be the service node C1 — the service node C2, the service node C3, or the service node C4.
Referring to fig. 3C, an example of path information corresponding to a service node set is shown.
And d5, determining the data processing mode corresponding to each service node according to the path information.
For example, referring to the path information shown in fig. 3C, since there is no neighboring service node in front of the service node C1 and there are neighboring service node C2, service node C3, and service node C4 behind the service node C1, determining the data processing manner of the service node C1 may include a reception condition indicating that the processing result of the service node C1 is sent to the service node C2, the service node C3, and the service node C4.
The service node C2 is preceded by a neighboring service node C1, and therefore, the data processing mode of the service node C2 includes a trigger condition, and the trigger condition is used for indicating that after the processing result of the service node C1 is received, the data request is processed based on the processing result of the service node C1. The service node C3 is preceded by a neighboring service node C1, and therefore, the data processing mode of the service node C3 includes a trigger condition, and the trigger condition is used for indicating that after the processing result of the service node C1 is received, the data request is processed based on the processing result of the service node C1. The service node C4 is preceded by a neighboring service node C1, and therefore, the data processing mode of the service node C4 includes a trigger condition, and the trigger condition is used for indicating that after the processing result of the service node C1 is received, the data request is processed based on the processing result of the service node C1.
And d6, sending the data processing mode corresponding to each service node to the service node.
And d7, each service node processes the data request by using a data processing mode.
After receiving the data request C, the service node C1 processes the data request C to obtain a processing result of the service node C1. Based on the reception condition of the serving node C1, the serving node C1 transmits the data request C and the processing result of the serving node C1 to the serving node C2, the serving node C3, and the serving node C4.
After the service node C2 receives the data request C and the processing result of the service node C1, based on the trigger condition of the service node C2, the service node C2 processes the data request C based on the processing result of the service node C1, and obtains the processing result of the service node C2. After the service node C3 receives the data request C and the processing result of the service node C1, based on the trigger condition of the service node C3, the service node C3 processes the data request C based on the processing result of the service node C1, and obtains the processing result of the service node C3. After the service node C4 receives the data request C and the processing result of the service node C1, based on the trigger condition of the service node C4, the service node C4 processes the data request C based on the processing result of the service node C1 to obtain the processing result of the service node C4, and thus, the processing procedure of the data request C is completed.
Of course, the application scenarios 1-3 are only examples of the present application, and are not limited thereto.
In one example, in a streaming computing scenario, a distributed task scheduling scenario, and an aggregation service processing scenario, computation paths similar to DAGs (directed acyclic graphs) are required, as shown in fig. 3A to 3C, and in order to obtain computation paths quickly in these scenarios, the computation paths can be obtained quickly by using the above method. In the above mode, the data processing mode does not need to be indicated in the code, but the path information is automatically generated, and the data processing mode corresponding to each service node is determined according to the path information, so that the problems of large development workload of the code, high development and learning cost, complex development difficulty and the like can be solved, the processing efficiency of each service node is improved, the development workload of a user is reduced, and the service experience is good.
In one example, the path information in this embodiment is specifically: a directional acyclic path based on a polymeric type (see fig. 3B); or, a non-convergent type directed acyclic path. Further, for a non-convergent based directed acyclic path, the method may include: a pipeline-based directed acyclic path (see FIG. 3A); or a directed acyclic path based on multiple parallel processes (see fig. 3C).
Wherein, the polymerization type-based directed acyclic path may refer to: starting from the starting vertex, all the pointed vertices converge to another vertex, starting from the one vertex, all the pointed vertices converge to another fixed point, and then looping, and finally all the vertices converge to the end point, as shown in fig. 3B and fig. 3D, a schematic diagram of a convergent type directed acyclic path is shown, and in this embodiment, fig. 3B is taken as an example for description.
In one example, when the data request requires a pipeline-like execution path, as shown in fig. 3A, an execution order may be marked for each service node, and then path information may be generated according to the execution order, where the path information may be a topology-like sequence 1234. After the service node a1 corresponding to the class topology sequence 1 executes the data request, the computing nodes of the whole pipeline are triggered, that is, the service node a1 corresponding to the class topology sequence 1, the service node a2 corresponding to the class topology sequence 2, the service node A3 corresponding to the class topology sequence 3, and the service node a4 corresponding to the class topology sequence 4 execute the data request respectively.
In an example, when the data request requires an aggregation-based execution path, as shown in fig. 3B, an execution order is marked for each service node, and then path information is generated according to the execution order, where the path information may be a topology-like sequence 1223. After the data request is executed by the serving node B1 corresponding to the class topology sequence 1, the aggregated execution path is triggered, that is, the data request is executed by the serving node B1 corresponding to the class topology sequence 1 first, then the data request is executed by the serving node B2 corresponding to the class topology sequence 2 and the data request is executed by the serving node B3 in parallel, and then the data request is executed by the serving node B4 corresponding to the class topology sequence 3.
In one example, when the data request is an execution path that needs to be processed based on multiple consumers in parallel, as shown in fig. 3C, each service node may be labeled with an execution order, and then path information is generated according to the execution order, where the path information may be a class topology sequence 1222. After the service node C1 corresponding to the class topology sequence 1 is triggered to execute the data request, the execution path of the parallel processing of the whole consumer can be triggered, that is, the service node C1 corresponding to the class topology sequence 1 executes the data request first, and then the service node C2, the service node C3 and the service node C4 corresponding to the class topology sequence 2 execute the data request in parallel.
