AI Technical Summary
Technical Problem
Generating replay files from capture files in database systems is a time-consuming and resource-intensive process that can lead to out-of-memory conditions, and existing methods lack efficient preprocessing and global sorting, resulting in inaccurate performance evaluations.
Method used
Implementing in-memory merge sort and a capture file reader framework to preprocess capture files, joining and sorting data efficiently to generate replay files, which are grouped by session ID, reducing memory and processing time.
Benefits of technology
The proposed method significantly reduces processing time and memory consumption while ensuring accurate replay file generation, allowing for more efficient performance evaluation of database systems.
