Thousands? In many scenarios I have worked with the number is millions or billions, but I do "data engineering". Want to tag all traffic on your website? 1 billion visits = ~375 visits a second. Some of the accounting systems I have worked with were raking in datasets ~300GB at a time that were almost purely compressed transactions. Some of the companies I have worked for in retail have thousands of stores and a pretty constant volume, getting to that rowcount for some of their customer tracking stuff would easily blow that out.
