Can it do joins? I may have missed it in the doc.

estebarb Oct 9, 2023 View on HN

The joins should be done inside the DB, not in an external server. Any SQL DB should be able to do that.

Are you implying you're not supposed to use joins in SQL?

cryptonector Jul 29, 2025 View on HN

What do you mean? It takes SQL queries. You use the `JOIN` keyword in the SQL to do joins.

Did you consider Clickhouse? join's are slow, but if your data is in a single table, it works really well.

giantDinosaur Oct 21, 2020 View on HN

wait, what? doesn't support joins? Things like this make me doubt my fundamentals. 'Are joins really necessary?' is the question now running through my mind ;-)

Errm, we're talking about performance of joins

joshu Nov 23, 2011 View on HN

That sounds like a join by another name :)

Did you look at the queries? There is not a single join in any of them.
