Real-Time Compressed Log Viewing via In-Memory Decompression Index
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional log file systems store redundant information, consuming storage resources and complicating data analysis, and existing compression methods are inefficient for real-time decompression and storage optimization.
Innovation Solution
The method involves decompressing compressed log data in memory using a decompression index that maps message signatures to message templates, allowing for real-time viewing and navigation of log files without extracting the entire file, reducing storage needs and improving analysis efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the entire compressed log file is decompressed for viewing, then complete log data is available for analysis, but storage requirements and processing time increase significantly
Solution Approach 1:
The patent divides the compressed log file into multiple blocks, where each block contains a portion of the compressed log messages. The system loads only the necessary blocks into memory for viewing, rather than decompressing the entire file. This segmentation allows selective access to log data, reducing storage requirements while maintaining data accessibility for analysis.
2Loss of information
If the entire compressed log file is decompressed for viewing, then complete log data is available for analysis, but processing time and system resources increase
Solution Approach 1:
The patent pre-computes and stores a decompression index during the compression phase. This index contains mappings from compressed log messages to their original formats. When viewing log data, the system uses this pre-computed index to rapidly decompress and display only the necessary portions, avoiding the need to decompress the entire file and significantly reducing processing time.
3Loss of information
If traditional log file systems store all log data, then complete log information is preserved, but storage resources are consumed and data analysis becomes complicated
Solution Approach 1:
The patent introduces a decompression index as an intermediary structure that bridges the compressed log storage and the original log format. This index enables efficient translation between the compressed representation and the human-readable format, allowing complete log information to be preserved in compressed form while simplifying data analysis through rapid, on-demand decompression of only the necessary data portions.

AI summary
Techniques are provided for decompression of compressed log data, such as for a real-time viewing of compressed log data. An exemplary method comprises: obtaining a compressed log file comprised of a plurality of compressed log messages, wherein a given compressed log message is comprised of one or more message variables and a message signature corresponding to a message template of the given compressed log message; and presenting a first subset of the compressed log file by translating, in memory, the message signatures of the compressed log messages within the first subset to corresponding message templates using a decompression index that maps a plurality of the message signatures to corresponding message templates. The first subset of the compressed log file may comprise a predefined number of lines surrounding a requested line of the compressed log file. In further variations, at least one additional subset of the compressed log file is precomputed using the disclosed decompression techniques.
