1. Title:

   • The title of the pull request is clear and concise, indicating that the changes are related to refactoring logging for rawlog and statement_info in mo1.2.

2. Body:

   • The body of the pull request provides relevant information about the type of PR, the issue it fixes, and the changes made.
   • It references issue [Subtask]: update logging mechanism for statement_info  #13625 and refactor mo logging for rawlog and statement_info #15877, which is good for tracking purposes.
   • The explanation of the changes is brief but informative, mentioning the modifications made to session id, transaction id, statement id handling, and the addition of SessionLoggerInfo in Pipeline.pb.

3. Changes in pkg/vm/process/types.go:

   • Addition of go.uber.org/zap/zapcore import: This addition seems unnecessary as zapcore is not used in the provided diff. It should be removed to avoid unnecessary imports.
   • Addition of github.com/matrixorigin/matrixone/pkg/common/log import: This import is added but not used in the provided diff. It should be removed if not utilized in the subsequent changes.
   • Addition of LogLevel and SessionId in SessionInfo: These additions seem relevant for logging purposes but ensure that they are used consistently throughout the codebase.
   • Addition of logger *log.MOLogger in Process: The addition of a logger is good practice for logging, but ensure it is utilized effectively in the codebase.

Suggestions for Optimization and Security:

1. Unused Imports:

   • Remove unused imports like go.uber.org/zap/zapcore and github.com/matrixorigin/matrixone/pkg/common/log to keep the codebase clean and avoid unnecessary dependencies.

2. Error Handling:

   • Ensure proper error handling mechanisms are in place, especially when dealing with logging operations to prevent potential runtime errors.

3. Nil Check:

   • Add nil checks before accessing properties in functions like GetTxnId and GetStmtId to prevent potential panics if sp is nil.

4. Consistency:

   • Ensure consistency in the usage of LogLevel and SessionId throughout the codebase to maintain clarity and avoid confusion.

5. Logging Usage:

   • Verify that the logger *log.MOLogger added in Process is effectively utilized for logging purposes in relevant parts of the codebase.

By addressing these suggestions, the codebase can be optimized for better performance, maintainability, and security.

Pull Request Review:

Title and Body:

The title of the pull request is clear and indicates that the changes are related to refactoring logging for rawlog and statement_info in mo1.2. The body of the pull request provides some context about the changes made and references the related issue and pull request numbers, which is helpful for tracking purposes.

Changes Made:

1. Added SessionLoggerInfo in pipeline.proto:
   • A new message SessionLoggerInfo has been added to pipeline.proto to include session, statement, and transaction IDs along with a log level.
   • The SessionLoggerInfo message includes fields for session ID, statement ID, transaction ID, and log level.
   • The LogLevel enum within SessionLoggerInfo defines different log levels such as Debug, Info, Warn, Error, Panic, and Fatal.

Suggestions and Security Concerns:

1. Security Concern - Logging Sensitive Information:

   • Storing sensitive information like session IDs, transaction IDs, and statement IDs in logs can pose a security risk if not handled properly.
   • Ensure that sensitive data is properly sanitized or encrypted before logging to prevent exposure of sensitive information.

2. Code Optimization - Enum Usage:

   • Instead of using numeric values for log levels, consider using the enum values defined in SessionLoggerInfo for better readability and maintainability.
   • Use the enum values directly in the code where log levels are set to avoid potential errors related to incorrect numeric values.

3. Code Clarity - Comments and Documentation:

   • Add comments or documentation to explain the purpose of the new SessionLoggerInfo message and its fields for better understanding by other developers.
   • Document the usage of the log levels and when each level should be used to maintain consistency in logging practices.

4. Code Refactoring - Consistency:

   • Ensure that the naming conventions and structure of the new SessionLoggerInfo message align with existing conventions in the codebase for consistency.
   • Check if any existing logging mechanisms need to be updated to utilize the new SessionLoggerInfo message for logging session-related information.

5. Testing - Unit Tests:

   • Consider adding unit tests to cover the new logging functionality introduced by SessionLoggerInfo to ensure its correctness and prevent regressions in the future.

6. Issue Reference - Link Correction:

   • The issue reference in the body of the pull request seems to have a typo in the URL format. Ensure that the correct link to the related issue is provided for easy navigation and tracking.

By addressing the security concerns, optimizing the code changes, improving code clarity through comments/documentation, ensuring consistency in code refactoring, and adding relevant unit tests, the quality and maintainability of the codebase can be enhanced.
