Message Queue Pre-Reading for FIFO Processing Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional message management systems in cloud computing face performance limitations due to sequential consumption requirements and random disk writes, which hinder processing speed and disrupt the first-in first-out (FIFO) characteristic of message queues, especially when concurrent consumption is not supported.
Innovation Solution
A message management method and apparatus that record and adjust a number range of consumable messages in a message queue, allowing for efficient pre-reading and management based on message status changes, ensuring the FIFO characteristic while improving processing speed by pre-reading messages with smaller numberings first and expanding the range for failed consumption attempts.

Engineering Contradiction Analysis
1Stability of the object's composition
If messages are consumed sequentially to maintain FIFO characteristic, then message order is preserved, but processing speed is limited
Solution Approach 1:
The system performs preliminary actions by pre-reading message bodies from disk to cache memory in advance of actual consumption. This allows the message queue metadata to maintain sequential FIFO ordering while the actual message data is loaded into cache for faster subsequent access, thus preserving order while improving processing speed.
Solution Approach 2:
The system segments message management into two independent parts: metadata management (which maintains sequential FIFO order for reliability) and message body storage (which can be pre-loaded into cache for speed). This segmentation allows the metadata to enforce strict ordering while the cached message bodies enable parallel pre-reading operations.
2Reliability
If message attributes are modified to track consumption status, then message tracking is improved, but random disk writes increase affecting system performance
Solution Approach 1:
The system extracts the message body data from the metadata structure and stores it separately in cache memory. Only essential metadata (message IDs, offsets, consumption status) remains in the queue structure, while full message contents are loaded into cache. This reduces the amount of data that needs to be written to disk and allows faster access to message contents.
Solution Approach 2:
The system introduces a cache memory as an intermediary layer between disk storage and consumption processing. The cache acts as a buffer that holds pre-read message data, reducing the frequency and impact of disk writes. This intermediary allows the system to maintain reliability through proper metadata tracking while improving performance by minimizing random disk access.
3Productivity
If messages are pre-read from disk to cache, then processing speed is improved, but disk I/O operations increase
Solution Approach 1:
The system performs preliminary pre-reading of message bodies from disk to cache before actual consumption occurs. By loading messages into cache in advance based on predicted consumption patterns, the system reduces the critical path I/O operations during actual message processing, thus improving processing speed while managing disk I/O through batch operations.
