Parallel SQL Script Execution via Comment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Running SQL scripts in a sequential manner is time-consuming, especially for large databases, and breaking them into multiple scripts for parallel execution is a complex and error-prone process due to dependencies within the script commands.
Innovation Solution
A method and mechanism that allow for the automatic parallel execution of SQL scripts by embedding control statements as comments, which direct a parallel script executor to break the script into sections that can run concurrently, using multiple execution threads and error handling control statements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a SQL script is executed in a sequential manner, then the execution is simple and reliable, but the execution time is long especially for large databases
Solution Approach 1:
The patent divides the SQL script into multiple independent sections using comment markers (e.g., --SECTION 1, --SECTION 2). Each section can be executed independently in parallel, reducing overall execution time while maintaining simple syntax. The script is segmented into manageable portions that can run concurrently without interfering with each other.
Solution Approach 2:
The patent introduces comment markers as intermediary elements that carry control information. These comments act as mediators between the script executor and the script content, providing instructions for parallel execution without requiring complex programming constructs. The comments serve as a simple interface for defining execution parallelism.
2Loss of time
If a SQL script is broken into multiple shorter scripts for parallel execution, then the execution time is reduced, but the organization and administration becomes complex and error-prone
Solution Approach 1:
The patent merges multiple script execution logic into a single unified script file by using comment markers to define sections. Instead of creating separate script files, the entire script remains in one location with clear delimiters indicating which portions can execute in parallel. This maintains ease of organization while enabling parallel execution.
Solution Approach 2:
The comment markers serve multiple functions: they define section boundaries for parallel execution, provide error handling instructions, and maintain script readability. This multi-functionality reduces the need for separate control mechanisms, simplifying administration while enabling complex execution patterns.
3Loss of time
If multiple scripts are created for parallel execution, then the execution time is reduced, but dependencies between script commands cannot be properly managed
Solution Approach 1:
The patent performs preliminary analysis of the script to identify dependencies between commands. Based on this analysis, it automatically assigns commands to different sections that can execute in parallel, ensuring that dependent commands are properly ordered. This preliminary organization ensures reliability is maintained while enabling parallel execution.
Solution Approach 2:
The patent incorporates error handling control statements that provide feedback mechanisms. When errors occur in parallel-executing sections, the system can detect and respond appropriately, maintaining reliability. The feedback loop ensures that dependency issues are caught and handled, allowing parallel execution without sacrificing reliability.
Data Source
AI summary
According to some embodiments, a script written in a scripting programming language may be received (e.g., by a script executer). It may be determined that a first line in the script comprises a first comment, and the first comment may be interpreted as an embedded parallel part control statement. Parallel execution of a portion of the script may then be automatically arranged in accordance with the parallel part control statement.
