Do you just want people to agree that 24+ hours is too long for an insert to take place? If so, I would agree that 24 hours is way too long to insert a *single* record. However, I've never tried inserting 77 million records so I'm not sure if 24 hours is unreasonable for that. Maybe others who have more experience with large databases can comment on that. Or are you asking a question? If so, what exactly *is* your question? Are you worried about why some records were missed or why the insert took so long or both? If you're trying to get some help with a problem, you'll have to give us more information. At the very least, we need to know something about your environment, like which version of MySQL you are using. We're likely to need to know more as we start to understand the question, such as your table definition(s), and we may need to see the code that is doing the inserts to see if we can help you optimize it. We may even need information about your hardware if this is a performance question to see whether the times you are getting are reasonable for your hardware.
