Signal interaction realization method, device and equipment, and computer readable storage medium

Abstract

The invention relates to the technical field of financial science and technology, and discloses a signal interaction implementation method, device and equipment and a computer readable storage medium.The method comprises the following steps: receiving a signal sent by an upstream workflow, performing primary packaging on the signal to obtain first signal data, and determining a target signal processing cluster corresponding to the first signal data; performing secondary packaging on the first signal data through the target signal processing cluster to obtain second signal data; determining atarget storage partition corresponding to the second signal data according to the data range of each pre-constructed partition in the target signal processing cluster; writing the second signal data into the target storage partition, and generating corresponding metadata information; and when a signal receiving request sent by a downstream workflow based on the signal is received, querying the metadata information to obtain a target storage position, and then obtaining the signal and returning the signal to the downstream workflow. According to the invention, the flexibility of workflow signalinteraction can be improved, and meanwhile, the performance of signal interaction in a high-concurrency scene is ensured.

Description

technical field [0001] The present invention relates to the technical field of financial technology (Fintech), in particular to a method, device, equipment and computer-readable storage medium for realizing signal interaction. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field, and the traditional financial industry is gradually transforming into Fintech. However, due to the security and real-time requirements of the financial industry, higher requirements are placed on technology. requirements. [0003] In the scheduling system, if two workflows need to interact with signals, a long socket (socket) connection needs to be established based on TCP (Transmission Control Protocol, Transmission Control Protocol TCP). Output streams send and receive signals. Specifically, if a process wants to send data to another process over the network, it can write to the output stream associated with the ...

AI Technical Summary

Problems solved by technology

Therefore, the existing workflow signal interaction scheme has the following defects: 1) The downstream workflow can only receive the signal when the downstream workflow starts first and the upstream sends the signal later, and the downstream workflow cannot flexibly define the scheduling time; 2 ) is not flexible enough, because the socket does not store data, if the downstream workflow needs to rerun, the upstream workflow must resend the signal; 3) There will be performance problems in high concurrency scenarios, once the downstream workflow receives Slower than upstream can send signal, may lose signal

Therefore, the signal interaction scheme in the prior art is less flexible and has performance problems
