Research direction

The issue discusses generating unique primary keys for transaction group ID (string) and transaction log ID (long). Review the codebase for existing ID generation, likely in transaction management classes. Check comments for any proposed solutions. Identify where GroupId and transaction log IDs are created, and propose a globally unique generation strategy, possibly using UUIDs or snowflake like algorithms.
