  • mySQL: How many rows in a table before performance is affected?

    - by Industrial
    Hi everybody, Is there a "known limit" for columns & rows in a mySQL table that when passed, it can be safe to say that performance is severely affected? I've think that I had heard that there is a "golden number" that you really dont want to exceed in either columns or rows in a table. - Or is it all about the size of the index and available RAM + CPU on the server? Thanks!
