Giving weird results, trying to fix. Is someone else able to run this on their computer and see what they get. |

@alamb Was this the sort of implementation you were looking for? (will add tests) |
Yes, exactly this -- thank you.
I will run it on a GCP VM and report back. Given most of those queries don't group on date/time/timestamp columns this seems somewhat suspicious |
And My conclusion is that the variability for the very fast queries (10s - 100s of ms) is significant. |
