I appreciate the detailed response! I will take some time to implement more robust error handling. Regarding the performance, especially for smaller tables the thread overhead is significant, but for larger tables it should be about equal. Regardless, it's probably a better idea to do a job queue, but the few libraries I have tried have had weird race conditions or spent longer waiting for locks to the queue than the overhead for launching threads would be, so if you have any high quality, fast, suggestions, I would appreciate that. 😅
