Method and system for dynamically adjusting number of threads based on distributed coordination system

Abstract

The invention discloses a thread number dynamic adjustment method and system based on a distributed coordination system, and belongs to the technical field of data processing, and the method comprises the steps: S1, receiving a whiteboard message of a room, and writing the whiteboard message into a cache corresponding to the room; S2, when it is judged that there is no thread for processing the whiteboard message of the same room at present, writing a flag bit into a first node instance of the distributed coordination system to send a trigger signal to a whiteboard message processor; S3, after the whiteboard message processor receives the trigger signal, creating a second node instance for sending the trigger signal to the long connection server, and starting a new thread to process the whiteboard message of the room. The technical scheme has the beneficial effects that the processing thread of the whiteboard message can be automatically created and destroyed based on the distributed coordination system, so fewer threads are reserved in the off-peak time period, the dynamic allocation and release of resources are realized, and the system resources are fully and reasonably utilized.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and system for dynamically adjusting the number of threads based on a distributed coordination system. Background technique [0002] The existing network teaching system usually includes teaching information providing terminal (teacher user terminal), teaching information receiving terminal (student user terminal), server (local server or background remote server), teaching equipment (electronic whiteboard, projection, etc.) and other equipment. Whiteboard messages in a single room are sent by terminals (including teacher user terminals and student user terminals). As the core business of teaching, whiteboard messages are particularly important for data consistency, and message loss and disorder are absolutely not allowed. [0003] In the online teaching scenario that maintains teachers and students, especially when meeting the needs of extra-curricular tutoring,...

Problems solved by technology

[0004] In the prior art, in order to improve the throughput of the system, the whiteboard message is usually processed by multi-thread / thread multiplexing. If the whiteboard message is processed by different threads, the whiteboard message sent first may be post-processed, and then in the There are inconsistencies in the restoration scene of the whiteboard message, causing abnormal classroom functions; at the same time, due to the randomness of sending out the whiteboard message in the room, the whiteboard message may not be sent for a long time, or the user may enter or leave the room at any time. Starting and maintaining this thread for a long time will cause a waste of system resources and cannot make full use of system resources. Due to memory constraints, the stack of a single thread occupies at least 512KB, which limits the total number of threads on a single machine. When a large number of concurrent access requests At this time, the system cannot flexibly expand the system, and the scheduling ability is insufficient. Therefore, in view of the above problems, it is urgent to design a method and system for dynamically adjusting the number of threads based on a distributed coordination system to meet the needs of actual use.
