I use DuckDB daily.

In short — It doesn’t crash often at all.

What you may be remembering were reports of exceptional cases where it didn’t handle out of memory errors well. I was one of the people affected. I was running complex analytic queries on 400 GB parquets and I only had 128GB memory. It used jemalloc which didn’t gracefully degrade. They fixed a lot of the OOM issues so it’s more robust now. I haven’t had a crash for a long time.

On normal sized datasets it never crashes.
