In a recent Office Hours post, David Reabow suggested letting ChatGPT answer a few of the questions y’all posted at http://pollgab.com/room/brento/. Brilliant! Let’s see how it does. I purposely cherry-picked the questions that I thought ChatGPT would have the easiest time answering. Rollback is single threaded asks: Hi Brent! An update statement has blocked all…

Some of the questions y’all post at https://pollgab.com/room/brento are pretty straightforward. Let’s get ‘er done. LetTheDbaHandleIt: My friend needs to track who has accessed what data.

So here are the questions in text form instead: Q: 22DBA: what performance recommendation you see people give all the time but it actually doesn’t…
