Embodiment 1

[0069] In embodiment one, if Figure 5As shown, when there are many end nodes of Dag1, such as Dag1 nodes Dag1-B1, Dag1-B2 and Dag1-B3 are end nodes and parallel nodes, Dag1 is a multi-task DAG, and the first nodes of Dag2 Dag2-A1, Dag2-A2 and Dag2-A3 respectively need to perform traversal detection execution results on the end nodes Dag1-B1, Dag1-B2 and Dag1-B3.... of Dag1. In this embodiment, in order to facilitate the detection of whether all the nodes of the previous DAG have been executed, after detecting that the last step of a Dag is multi-task parallelism, after the parallelism ends, an end identifier is added at the end of the end node, such as an end placeholder or virtual nodes. Among them, the end placeholder (virtual node) does not process anything in the process node for the convenience of connecting the following Dag. If it is found to be an end placeholder (virtual node), the process automatically skips executing the node in the next Dag. Specifically, the t...

Abstract

The invention discloses a node combination scheduling method and device, equipment and a storage medium. The method comprises the following steps: obtaining a DAG dependency relationship correspondingto each directed acyclic graph DAG and a node dependency relationship corresponding to each node in the DAG, and combining to generate a corresponding serial DAG according to the DAG dependency relationship and the node dependency relationship; when a target DAG in the serial DAG is executed, judging whether all nodes of a previous DAG corresponding to the target DAG are scheduled and executed ornot according to the DAG dependency relationship and the node dependency relationship; and if all the nodes of the previous DAG corresponding to the target DAG are scheduled and executed, schedulingand executing the target DAG to schedule and execute the nodes of all the DAGs in the serial DAG. Based on the DAG dependency relationship and the node dependency relationship, multiple DAGs are combined into one serial DAG, layer-by-layer nesting of the DAGs is avoided, the scheduling code logic is simplified, the development efficiency of the scheduling code is improved, and the convenience andefficiency of subsequent business process scheduling are improved.

Description

technical field [0001] The present invention relates to the technical field of financial technology (Fintech), and in particular to a method, device, equipment and computer-readable storage medium for merging and scheduling nodes. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field. The traditional financial industry is gradually transforming into financial technology (Fintech), and the process engine scheduling technology is no exception. However, due to the security and real-time nature of the financial industry Requirements, but also higher requirements for process engine scheduling technology. Existing business processes are generally scheduled through the process engine, and each link of the business process is abstracted into a process node. When the process engine schedules, the order and sequence of all Dags (Directed Acyclic Graph, Directed Acyclic Graph) All dependencies need to b...
