I’m a big fan of tmducken. We use it heavily in our prod systems. That said, we’ve recently started exploring ducktape [1] in our new projects and have been really impressed with the performance. It also support more complex types on insertions and queries which has been helpful for us. Not affiliated with the project, but just wanted to show it some love since it’s a bit newer. It was created by an active contributor to tmducken.
It really is - we use duckdb as our main workhorse in our entire stack.
As a side note, thank you for all the work you have done in the Clojure ecosystem! Techascent’s data science packages was a major tipping point in my company’s decision to build our data science ecosystem in Clojure and has been wonderful to work with.
