That was fast. I was looking into recent HN datasets, and they are impossible find.

Complete and continuously updated: https://play.clickhouse.com/play?user=play#U0VMRUNUIG1heCh0a...

If the last story on HN was at December 26, that is.

Continuously updated != instantly updated

Continuously would suggest to me that the data is never far out of date, and a few days might be considered far in this case.

Perhaps “regularly updated” would be less contentious wordage?

It's available on BigQuery and is updated frequently enough(daily I think).
