- Research direction
- Examine the existing Hmily codebase to understand how SQL statements are currently managed in transaction logs. The comment on the issue may contain additional context; review it for any implementation hints. Study Apache Calcite's documentation to learn how to parse SQL into an AST and map it to a custom Statement class. Look at how other distributed transaction frameworks implement SQL parsing for rollback to identify best practices.
